By Debbie Townsend
(continued on Page 2)
What currently looks like a giant, muddy hole in northeast Edina is part of an innovative project that will reduce the flood risk for many homes, restore natural areas and renew trails and fields at Weber Park.
The $12.5 million Morningside
Flood Infrastructure Project
will almost double the size of
Weber Pond and increase the
Lynn/Kipling area so they can
store significantly more floodwater
during and after storms.
“This is the top flood-risk neighborhood in the city,” said Engineering Services
Manager Ross Bintner. “That’s why we started this project there.”
The flood risk is no joke. Every year there is a 1 percent chance of 7.5 inches of
floodwater in a 24-hour period, what sometimes is called the “100-year flood,”
though that is proving to be a misleading description. Imagine 7.5 inches of
water in your basement or pouring in around your front door.Iskaan-garee koodhkan oo ku fiiri soomaali

Your Drinking Water
Is Certified Safe
Monitoring done on Edina’s and
Minneapolis’ drinking water last year
shows that it is safe. The City’s goal
is to provide residents with water
that surpasses both state and federal
requirements for safety and quality.
This year’s report shows Edina’s water
surpasses regulatory standards on all
counts. Morningside Neighborhood
residents who receive their water
from the City of Minneapolis will find
information detailing the quality of
Minneapolis’ water in the report, too.

EdinaMN.gov/WaterReports
Morningside Flood Infrastructure Project (Continued from cover)
The damage to the Morningside
Neighborhood for such a storm is
estimated at nearly $3 million, Water
Resources Manager Jessica Wilson said.
The project reduces potential flood
damages in this scenario by 40 percent,
which equates to more than $1 million.
It also removes the flood risk entirely for about two dozen homes and reduces it for more than 100 homes.
It isn’t just the risk of flooding that
gets reduced. Sewer systems are also
connected, so if the basement of one
house floods, the dry home next door
still might suffer a sewer backup, Bintner
said. That’s a mess that’s both gross and
expensive to fix. And many people don’t
have insurance that covers it.
Another important factor in this project:
It will not increase flood risk for any
structure in Edina or neighboring
communities. It’s not diverting
floodwaters into another neighborhood.
Instead, it greatly expands water storage
and includes a pump station that controls
downstream releases to maximize
storage. The station is connected to
National Weather Service data, so
it will draw down the water level of
Weber Pond and the Lynn/Kipling
area ahead of a storm to make room
to store floodwater.
“This is next-level flood management,” Wilson said. “It’s very inexpensive to operate it this way, and we get a lot more flood benefit.”
More cost savings are in the timing. The
required piping and related infrastructure
is being done at the same time as street
reconstruction in the neighborhood,
when the streets are already opened
up for such work.
“This is a generational opportunity to make investments in pipes and underground infrastructure,” Bintner said. “It’s not cheap if you do it off cycle.”
Nature Restoration
The area north of Weber Park, known as Weber Woods, has long been a haven for nature and nature lovers. It’s home to all sorts of wildlife and popular for dog walkers and people who like a stroll through the forest.
But it’s also been home to buckthorn and
other invasive species, diseased trees and
ash trees under attack from the emerald
ash borer. As part of the project, invasive,
diseased or disease-prone trees have
been removed.
“Now you can actually see some
lovely oak trees, not just buckthorn,”
Wilson said.
More than 1,000 climate-adaptive trees
will be planted to replace those trees and
the healthy ones that had to be cut down
for the expanded pond. The new trees
will include fruit and nut-bearing species
that will provide forage for animals.
Wetland plants that support waterfowl,
turtles and frogs will be planted along
the pond’s edge. Native shrubs, grasses
and wildflowers will be grown from seed
to both restore soil health and provide
wildlife habitat, including for pollinators.
A temporary cover crop will be put in this fall before most of the seeding and planting is done in spring 2023.
“We are going to put back a healthier
landscape,” Wilson said. It will be similar
to restoration projects at Braemar Golf
Course and Arden Park. Like those, it will
take a few years for nature to cover the
scars of construction and begin to fill in.
A maintenance program has already been
set to ensure routine inspections of the
replanted areas to keep the restoration
on track.
Park Uses
For neighbors, the biggest downside
to the project may be losing access to
some favorite Weber Park features
during construction.
The multiuse fields are unavailable
this summer, as they are being lowered
and moved a bit to make them capable
of emergency floodwater storage in
huge storms.
“It would only be in really, really big
events,” Wilson said. “It’s going to
be rare.”

‘Now you can actually see some
lovely oak trees, not just buckthorn.’
–Water Resources Manager Jessica Wilson
Good news is the new fields are expected
to open for softball, T-ball, soccer and
other sports in 2023 as soon as the grass
gets established.
The hockey rink will remain as is and will be open this winter. The playground is similarly unaffected.
Trails will be the last to open because of
all the seeding and planting. Park users
will need to stick to designated areas and
not breach fence lines or construction
areas. This is for more than just safety;
people might unknowingly trample
over delicate seeds and plants.
Once open, the new trail system will offer
improved pedestrian access to the park,
nature trails, bridge crossings and ADA-
compliant trails in Weber Park.
Many of the changes people will see –
and won’t see – are due to neighborhood
input. For example, more developed
features for Weber Park were proposed,
but nearby residents wanted to keep
the area to basic trails and the amenities
there now.
“This final plan had a lot of neighborhood input. We made many changes based on that, and overall people have been supportive,” Wilson said.
She and Bintner both expect this project
will win awards for its innovation
and solutions. It’s already attracted
a $250,000 Department of Natural
Resources grant. Other funding comes
from a stormwater fee on utility bills.
The project is not paid for out of street
reconstruction assessments.
The biggest reward, however, would be
in what doesn’t happen: flooding of
nearby homes.
This is the first such flood infrastructure project in Edina, but Bintner expects others to follow in neighborhoods that have high flood risk.
“Some of the techniques we are learning
from this project we can also take
citywide,” he said.

Summer brings many things to look forward
to, including cookouts, days on the lake and
longer evenings. But the warm summer air
can also bring unstable skies. That’s why it’s
important to not only know how to prepare
for severe weather, but also how to handle
cleanup after it has passed. The impacts
of storms, even if not overly damaging,
can still leave residents with questions
if they come across things like downed
branches, standing water in the street
or a traffic light outage.
“After any significant weather event, we
dispatch crew members across the city
to assess street, utility and other public
infrastructure conditions. Reporting an
issue in your neighborhood helps us to
more quickly identify areas of damage
or safety concerns and resolve them,”
said Public Works Director Brian Olson.
“Even though some things will be the
responsibility of the individual homeowner
and not the City, our staff can still advise
and talk through any questions a property
owner may have regarding storm cleanup
and point them in the right direction of
who to contact for further help.”
Olson and Fire Chief Andrew Slama offer residents several tips to the right for severe weather cleanup.
For more information on severe weather cleanup, contact Public Works, 952-826-0376. For more information on emergency preparedness, visit EdinaMN.gov/Emergency-Preparedness or contact the Fire Department, 952-826-0330.
City Offers Tips for Severe Weather Cleanup
• If there is a traffic light outage, call the Police Department’s non-emergency 24-hour dispatch, 952-826-1600, or report it through Edina 311. If there is a traffic light outage with a related accident, call 911.
Traffic Light Outage
• Power lines in Edina are owned and operated by Xcel Energy. For a power outage in your home or business, contact Xcel Energy to report it. You can report an outage by calling 800-895-1999, texting OUT to 98936, via the Xcel Energy app or online at xcelenergy.com.
• If there is a downed power line, keep a safe distance of at least 25 feet. Call 911 to report it and then make a second call to Xcel Energy.
Power Outage/Downed Power Lines
• If there are downed branches or trees lying on or within public property (streets, sidewalks, trails or parks), call the Police Department’s non-emergency 24-hour dispatch, 952-826-1600, or report it through Edina 311. When branches or trees from an individual’s private property fall within the roadway or sidewalk and are removed by the City, they are not hauled away. Instead, they will be placed in the adjacent property owner’s yard.
• In extreme cases of widespread tree damage, the emergency management command staff, Mayor and City Manager may choose to identify organized drop-off locations and times for coordinated tree and branch removal.
Downed Branches or Trees
• If you encounter flooding or standing water on a street, call Public Works, 952-826-0376, or the Police Department’s non-emergency 24-hour dispatch, 952-826-1600. The on-call Public Works Supervisor will visit the site and evaluate the situation. If the flooding is deemed detrimental to travel, the road will be closed. If the standing water is minor, you can report it through Edina 311.
• Public Works monitors the water levels of Minnehaha Creek and Nine Mile Creek, often many times per day in the spring and prior to rainstorms. By monitoring the discharge from Lake Minnetonka, it can often be predicted when water levels will spill outside the banks of the creeks. In preparation for this, Public Works will make sandbags to distribute to residents.

You can submit any non-emergency
problems encountered within the City
through Edina 311. Slama says that a
non-emergency problem can be thought
of as one that “does not cause harm or
risk if not addressed immediately.”
There are currently over 20 different
reporting categories available. For
example, categories related to weather

In the case of a tornado or a tornado-like event, go to the lowest floor and shelter in a small center room like a bathroom or
closet, under a stairwell or interior hallway with no windows. If possible, cover yourself with thick padding (mattress, blankets,
etc.) to protect yourself from falling debris.
After a tornado, the City will initiate its emergency response protocols and communicate further instructions by any way possible.
“Ahead of a storm, City staff monitor communication from the weather services and coordinate with other City departments to
ensure staff is prepared to respond to an increase in calls. We monitor the storm throughout the duration and then perform a
damage assessment after the weather system has moved through the city,” said Slama.
“After a storm, residents should stay calm, perform a damage assessment, notify 911 of any emergency, take photos if there is
damage and contact your insurance company if needed,” Slama said. “Be wary of damage and downed power lines the storm
might have caused. You should always call 911 if you feel like you are in a situation where your safety or the safety of others is
at risk or that extensive property damage may occur.”

More than a dozen streets in Edina will
get a fresh new look this year, as the
Public Works Department continues its
annual mill and overlay program in 2022.
The 13 projects due for a refresh
include major thoroughfares along with
neighborhood avenues and drives. Work
begins each year in June, with the goal
of completion before the first snow falls
in late autumn. The Streets Division is
projected to complete seven roadway
miles in 2022.
In a mill and overlay project, the top few
inches of the roadway are ground down
before a new, smooth layer of asphalt is
laid down. Such projects are an integral
component of the City’s pavement
management program. Along with street
reconstruction, positive changes have
been seen in the Pavement Condition
Index, which Public Works Director
Brian Olson explains is a metric used to
determine a street’s estimated lifespan.
Olson said the City’s network average PCI
jumped to 76 in 2021, up from 51 in 2012.
Below are the streets slated for mill and
overlay this year:
• Brookside Avenue (north city border to Interlachen Boulevard)
• Kelsey Court and Kelsey Terrace (south from Interlachen to new pavement)
• West Frontage Road (Richmond Drive to Benton Avenue)
• Colonial Way (Olinger Boulevard to Tracy Avenue)
• View Lane (Schaefer Road to Vernon Avenue South)
• Dovre Drive (Lincoln Drive to Biscayne Boulevard)
• Lincoln Drive (Londonderry Road, Vernon to Gleason Road)
• Gleason Road (McCauley Trail West to Valley View Road)
• Indian Hills Road, Pawnee Road, Apache Road (Gleason Road to McCauley Trail South)
• 64th Street West (West Shore Drive to 66th Street)
• Xerxes Avenue South (66th Street South to Richfield)
• Grandview Square (around park and entrance and exit to Sherwood Road and Eden Road)
• Valley View Road (east frontage road to Washington Avenue)
While there aren’t specific dates for each
project, once residents see utility and
concrete workers from the City starting
to repair curbs, catch basins and other
components of the street, that’s a good
sign that the mill and overlay is about
to occur. A letter is mailed to affected
areas before the work starts. By sending a
reminder, the division aims to lessen the
inconvenience to nearby neighbors and
remind them the work is not assessed to
the residents, but instead paid out of the
City’s Street Maintenance Fund.
“When our utility and concrete crews
are in there, it’s all spot work, so we
don’t shut anything down,” said Streets
Supervisor Shawn Anderson. “When I
come in to do the mill and overlay, it’s
a little more extensive, but we still don’t
shut neighborhoods down completely.
The only time it’s critical for a resident
to not access their driveway is when
we come by with the paver and the hot
asphalt. But that usually takes a day, and
it’s open by the time the resident gets
home from work. We don’t shut anything
down completely unless we absolutely
have to. Schedules can be adjusted a bit
to assist residents, with rain being the
only culprit that really slows progress.”
The process continues smoothly
throughout the summer, with rain being
the only factor that can slow it down.

with Mill and Overlay Program

“We definitely want to work around things like grad parties,
garage sales, things like that,” Anderson said. “The notices have
my number, and we like communication. We try to work around
as much as we can.”

The City has two street reconstruction
projects planned for 2022.
The Road to Reconstruction
Each year, a quarter of Edina’s roadways
are evaluated using the Pavement
Condition Index (PCI) method. A PCI is
measured from zero to 100, ranging from
a failed or gravel road to a brand-new
one. When a neighborhood’s average
PCI drops below a certain threshold, it is
placed into the reconstruction planning
process. In addition to PCI, other
factors considered when determining
neighborhoods with the highest needs
are the condition of underground public
utilities, gaps in pedestrian infrastructure
and age of original construction.
Edina’s existing streets were originally
constructed primarily between the 1940s
and 1980s. Street reconstruction is more
cost-effective than other maintenance
strategies once roads are at this age
and condition. Because of this, the City
began a complete street reconstruction
program in 1998 and anticipates finishing
in the mid-2040s, currently completing
about two to four miles per year.
Before 2022, the roadway portion of street reconstruction was fully funded through special assessments to property
owners. However, in July 2021, the Edina
City Council approved a new funding
model that will be phased in until 2036.
Each year between now and then,
street reconstruction will become less
funded through assessments and more
through property taxes. The last year of
assessments will be 2036 for 2035 street
construction projects, with all projects
after being entirely funded through
property taxes.
For those interested in learning more
about the street reconstruction
process, additional resources such
as informational videos and the five-
year project map are available at
BetterTogetherEdina.org/streetprojects.
Current Projects
Project areas will be divided into
smaller phases that will be completed
in 12-week increments. Road closures,
detours and the phasing plan will be
posted on BetterTogetherEdina.org
when applicable.
Blake Road A, B & C
A one-mile stretch of Blake Road from
Spruce Road to Scriver Road is being
reconstructed due to deteriorated
pavement, lack of sidewalks and high
traffic volumes at the intersection of
Blake Road and Interlachen Boulevard.
Blake Road is designated as a Municipal
State Aid Street (MSAS) by the City
as it is considered more regional in
nature. As such, 80 percent of the street
reconstruction project will be funded
by the State.
Director of Engineering Chad Millner says
the main benefits of this project will be
improved pedestrian access, pedestrian
safety and traffic operations.
“We’re adding big, wide sidewalks the
entire one-mile stretch on one side.
There are no sidewalks today, so people
are currently biking and walking in what
is a very busy street,” said Millner.
In addition to added safety, the new pedestrian infrastructure will aid in transportation access, providing improved connections to the future Southwest Light Rail Transit Station on Blake Road in Hopkins.
Another important feature of the
project is the construction of a mini
roundabout at the intersection of
Interlachen Boulevard.
“The roundabout will provide safety
and traffic operation improvements,
including slowing cars when entering
the roundabout, providing sidewalks
and dedicated crosswalks and reducing
traffic queuing to the south.”

City to Complete Reconstruction Projects on
Blake Road, in Morningside Neighborhood
The Blake Road Project Includes:
• Complete reconstruction of the asphalt pavement
• Full installation or replacement of concrete curb and gutter
• Construction of a mini roundabout at the Interlachen Boulevard intersection
• Construction of two 5-foot on-street concrete bike lanes
• Construction of a 6-to 12-foot concrete sidewalk along the south and west sides of the street
• Replacement of water main and water services south of Interlachen Boulevard
• Replacement of fire hydrants and water main gate valves
• Improvements to the storm sewer system
• Structural lining of the sanitary sewer main
• Street lighting at roundabout
• Sheet pile retaining walls adjacent to Mirror Lakes
• Modular block retaining walls along west side of Blake Road south of Interlachen Boulevard
Morningside D & E
Approximately two miles of roadway in the Morningside D & E Neighborhood is being reconstructed due to deteriorated pavement and the need for flood mitigation.
The reconstruction is in conjunction
with the Morningside Flood Infrastructure
Project, and storm sewer pipes will
be significantly increased to move
floodwaters to the stormwater ponds at
Weber Park for additional flood storage.
(You can learn more about the
Morningside Flood Infrastructure
Project on Pages 1-3.)
Assistant City Engineer Aaron Ditzler says about two thirds of the project area will be a standard reconstruction. The size and depth of the new storm sewer pipes needed to prevent flooding, might cause residents more disruptions, Ditzler cautioned.
“Our largest pipe in this project is 6 feet
in diameter or 72 inches. For comparison,
most of our pipes in other projects are 12
to 15 inches in diameter.”
The larger pipes must be buried down
15 feet, instead of the typical 3 to 5 feet,
to avoid conflicting with the sanitary
sewer pipes. Ditzler said the sheer size
of the resulting trenches will require
that some of them be left open but
secured overnight, as filling them in
with soil each night would prevent the
project from being completed in one
construction season.
“We’re providing additional safety features with how big and deep these pipes are. There will either be steel plates to cover the open trenches overnight, or concrete barriers and fences will be installed around the open trenches to keep people out overnight for safety.”
The trenches will be lower than the
groundwater level in the neighborhood,
so pumps and generators will be required
to run continually to keep them dry
enough to work in.
“Whenever possible, we will place
the generators strategically in the
neighborhood, so they are as far away
from homes as possible while still
remaining effective,” said Millner.
The City will mail a notification and host a meeting with the Morningside Neighborhood residents who are in the portion of the neighborhood most impacted.
“We feel the main benefit to the
residents, the increase in flood hazard
resiliency across the neighborhood with
no increase in risk to any property, will
outweigh any inconveniences from the
reconstruction process to get there,”
said Ditzler.
The Morningside Project Includes:
• Complete reconstruction of the asphalt pavement
• Full replacement of the concrete curb and gutter and sidewalks
• Partial replacement of fire hydrants and water main gate valves
• Replacement of water services
• Structural lining of the sanitary sewer main
• Improvements to the storm sewer system, including flood risk reduction improvements
What to Expect
Daily, those who live in a reconstruction
area should check their front door for
time-sensitive information. The City will
leave a notice during inconveniences such
as short-term loss of water service or
driveway access.
9
Weekly, residents are encouraged
to visit the Street Projects section of
BetterTogetherEdina.org where updates
will be posted on both projects, including
planned road closures or detours. In
particular, as a regional roadway, the
reconstruction of Blake Road will have
broader traffic impacts on the community.
Anticipate extra travel time if you are
heading near either neighborhood.
Residents can also sign up to receive text message notifications related to urgent and unexpected impacts on the projects by texting BLAKE or MSIDE22 to 57838. More information on text messages can be found at EdinaMN.gov/Texts.
The City will repair, replace or reinstall
any private infrastructure disrupted by
the reconstruction. Examples include
mailboxes, steps, landscaping, irrigation
systems and pet fences within the public
right-of-way. Landscaping and plants will
be restored as close to their original state
as possible.
“Reconstruction can feel like a long
process for residents. We are committed
to making it more manageable by
addressing questions and concerns in a
timely manner, whether that’s regarding
access, private infrastructure or other,”
said Millner. “We’ll have a staff member
overseeing the contractors at both
neighborhoods every day, so we can even
make a personal house call at a
resident’s request.”
Both projects are scheduled to be mostly complete by November.

People of Public Works
Utilities Employee Shares Journey to Edina
By Ricardo Acosta
Chadwick Syverson recently joined the Public Works Department’s Utilities Division, focusing on underground construction like repairs and water main replacements.
“I like working here. The guys are a lot
of fun – they are all characters, which
is nice,” said Syverson. “When you’re
having a tough day, there are always
a couple of people to pick you up and
push you forward.”
A native of Coon Rapids, Minnesota,
Syverson graduated from Bemidji State
University with a degree in criminal justice.
When he struggled to find work in the field
and needed to pay off student loans, he
started work at an excavating company
owned by a friend’s father.
“After a year, then two, three, four, you start running equipment and start liking it even though it can be a bit of a back-breaking job sometimes,” Syverson explained of his start in construction. “But the job was fun and I liked it a lot.”
He ended up working at Mattco Excavating
for nearly five years before making the
decision to take a job with the City of
Chanhassen. “I ended up talking to City
employees usually on sewer inspections
and I was like, ‘I can probably do that.
There’s a little more of a future
in this than excavating.’”
After working in Chanhassen for a little over two years, Syverson was ready for the next step in his career path.
“Everyone was impressed with
him and said he was likable
and trainable,” said Utilities
Supervisor Nathan Kaderlik.
“I was impressed with his
knowledge of underground
work; knowing the
underground utilities is vital.”
Syverson was hired in
November 2021 as a Utility
Service Worker. He is
responsible for repairing and
replacing water and sewer
pipes, maintenance holes and
water main breaks. He also
assists with seasonal duties
like snow removal.
One of Syverson’s most memorable learning experiences on the job so far was his first water main break in the winter. Syverson recounted how he used to be the one to operate the excavator for City workers, but this was the first time he was the one in the hole.
“It’s kind of tough when it’s all white from
the snow and you don’t know the streets
all that well and kind of just fumbling
through learning what Edina is,” said
Syverson. “But I like it here and I hope
to stick around for as long as I can.”

PipelinePUBLIC WORKS
By Dan Reisig
Major improvements to the City of Edina’s public works infrastructure are coming soon, and residents likely won’t even know it’s happening.
That’s because of a computer-based
system known as SCADA, or Supervisory
Control and Data Acquisition system. It
forms the backbone of how City crews
monitor all of the utility sites, such as
water, wastewater and storm stations,
without having to be on site at each.
The City is in the midst of a $1.7 million
upgrade to its SCADA architecture that
began last summer.
“Before SCADA was implemented in the
city, they would do rounds every day and
go site to site and take numbers and notes
and check up on things,” said Utilities
Supervisor Nathan Kaderlik. “Technology is
always improving, so we are upgrading our
current SCADA system.”
Kaderlik says the current system was
installed around the year 2000. They are
SCADA Investment to Ensure Continued Smooth Operation of City Utilities
hoping the new-and-improved system will
get similar if not longer usage.
“The components are getting old and outdated. Replacement parts are few and far between. We are getting to the end of the lifetime of the current parts. We decided to do the upgrade now before something big happened,” he explained.
“By adapting to newer technologies,
I.T. and Public Works were able to work
together to save on hardware costs,” said
I.T. Systems Administrator Nick Lovejoy.
“It’s important to us to balance utilizing the
latest cutting-edge upgrades with ensuring
stability for our system and its users.”
It’s important to note that a system
failure wouldn’t necessarily impact the
end user – the resident turning on their
faucet or flushing their toilet – but rather
on the side of the Public Works staff,
losing the ability to monitor and program
operations remotely. SCADA technology
works best when operators can program
their processes and capture data to
improve efficiency.
“A big part of this project has us doing
site work as well – upgrading all the
controls and programming pieces of it
because those are becoming obsolete, and
we’re upgrading to the new technology,”
Kaderlik said, noting that new technology
allows staff to continue to monitor and
troubleshoot more easily.
The project was slated to be done in May, but due to supply chain issues and backorders for necessary parts, it’s been pushed out. Once completed, the SCADA upgrade will allow the City to proactively ensure a continued high level of service and support for its utilities.
“If anything does happen, we do have
backup, and we do have redundancy, ”
Kaderlik explained. “We also are capturing
errors as well that we didn’t see before.
It’s going through with a fine-tooth comb,
and making sure everything is properly set
and programmed so that we can prevent
failures in the future.”

Making Your Water Safe
Edina drinking water comes from a
groundwater source: 18 wells ranging
from 381 to 1130 feet deep, that draw
water from the Prairie Du Chien-Jordan,
Mt. Simon and Jordan aquifers.
Edina works hard to provide safe and
reliable drinking water that meets federal
and state water quality requirements.
The purpose of this report is to provide
information on your drinking water
and how to protect our precious
water resources.
Contact Public Works Coordinator
Dave Goergen at 952 826-0312 or
dgoergen@EdinaMN.gov if you have
questions about Edina’s drinking water.
You can also ask for information about
how you can take part in decisions that
may affect water quality.
The U.S. Environmental Protection Agency
(EPA) sets safe drinking water standards.
These standards limit the amount
of specific contaminants allowed in
drinking water. This ensures that tap
water is safe to drink for most people.
The U.S. Food and Drug Administration
regulates the amount of certain
contaminants in bottled water. Bottled
water must provide the same public
health protection as public tap water.
Drinking water, including bottled
water, may reasonably be expected
to contain at least small amounts
of some contaminants. The presence
of contaminants does not necessarily
indicate that water poses a health risk.
More information about contaminants and
potential health effects can be obtained
by calling the Environmental Protection
Agency’s Safe Drinking Water Hotline at
1-800-426-4791.
Edina Monitoring Results
This report contains our monitoring results
from Jan. 1 to Dec. 31, 2021.
We work with the Minnesota Department
of Health to test drinking water for more
than 100 contaminants. It is not unusual
to detect contaminants in small amounts,
since no water supply is ever completely
free of them. Drinking water standards
protect Minnesotans from substances that
may be harmful to their health.
Learn more by visiting the Minnesota
Department of Health’s webpage,
www.health.state.mn.us/communities/
environment/water/factsheet/sampling.html.
How to Read the Water
Quality Data Tables
The tables on the following pages show
the contaminants we found last year or
the most recent time we sampled for that
contaminant. They also show the levels of
those contaminants and the EPA’s limits.
Substances that we tested for but did not
find are not included in the tables.
We sample for some contaminants less
than once a year because their levels in
water are not expected to change from
year to year. If we found any of these
contaminants the last time we sampled
for them, we included them in the tables
with the detection date.
We may have done additional monitoring
for contaminants that are not included in
the Safe Drinking Water Act. To request a
copy of these results, call the Minnesota
Department of Health at 651-201-4700
between 8 a.m. and 4:30 p.m. Monday
through Friday.
Some contaminants are monitored
regularly throughout the year, and rolling
(or moving) annual averages are used
to manage compliance. Because of this
averaging, there are times where the
Range of Detected Test Results for the
calendar year is lower than the Highest
Average or Highest Single Test Result,
because it occurred in the previous
calendar year.
Definitions
AL (Action Level): The concentration of a
contaminant which, if exceeded, triggers
treatment or other requirements which a
water system must follow.
EPA: Environmental Protection Agency
MCL (Maximum contaminant level): The
highest level of a contaminant that is
allowed in drinking water. MCLs are set as
close to the MCLGs as feasible using the
best available treatment technology.
MCLG (Maximum contaminant level goal):
The level of a contaminant in drinking
water below which there is no known or
expected risk to health. MCLGs allow for
a margin of safety.

Fluoride 4.0 ppm 4.0 ppm 0.6 ppm 0.59-0.61 ppm NO Erosion of natural deposits; water additive to promote strong teeth
Potential Health Effects and Corrective Actions
(If Applicable)
Fluoride: If your drinking water fluoride levels
are below the optimal concentration range of
0.5 to 0.9 ppm, please talk with your dentist about how you can protect your teeth and your family’s teeth from tooth decay and cavities.
For more information, visit https://www.health.
state.mn.us/communities/environment/water/
com/fluoride.html.
Fluoride is nature’s cavity fighter, with small
amounts present naturally in many drinking
water sources. There is an overwhelming weight of credible, peer-reviewed, scientific evidence that fluoridation reduces tooth decay
and cavities in children and adults, even when
there is availability of fluoride from other
sources, such as fluoride toothpaste and mouth rinses. Since studies show that optimal fluoride levels in drinking water benefit public health,
municipal community water systems adjust
the level of fluoride in the water to an optimal
concentration between 0.5 to 0.9 parts per million (ppm) to protect your teeth. Fluoride levels below 2.0 ppm are not expected to
increase the risk of a cosmetic condition known
as enamel fluorosis.

Monitoring Results –
Unregulated Substances
In addition to testing drinking water for
contaminants regulated under the Safe
Drinking Water Act, we sometimes also
monitor for contaminants that are not
regulated. Unregulated contaminants do
not have legal limits for drinking water.
Detection alone of a regulated or
unregulated contaminant should not cause
concern. The meaning of a detection
should be determined considering current
health effects information. We are often
still learning about the health effects, so
this information can change over time.
The following table shows the unregulated
contaminants we detected last year, as
well as human-health based guidance
values for comparison, where available.
The comparison values are based only
on potential health impacts and do
not consider our ability to measure
contaminants at very low concentrations
or the cost and technology of prevention
and/or treatment. They may be set at
levels that are costly, challenging, or
impossible for water systems to meet (for
example, large-scale treatment technology
may not exist for a given contaminant).
A person drinking water with a
contaminant at or below the comparison
value would be at little or no risk for
harmful health effects. If the level of a
contaminant is above the comparison
value, people of a certain age or with
special health conditions – like fetuses,
infants, children, elderly and people
with impaired immunity – may need to
take extra precautions. Because these
contaminants are unregulated, EPA and
MDH require no particular action based on
detection of an unregulated contaminant.
We are notifying you of the unregulated
contaminants we have detected as a
public education opportunity.
More information is available on
MDH’s website:
• A-Z List of Contaminants in Water
(https://www.health.state.mn.us/

Making Safe Drinking Water
Edina residents in the Morningside
Neighborhood receive their water
from the City of Minneapolis. Drinking
water from the City of Minneapolis
comes from surface water drawn
from the Mississippi River.

How to Read the Water
Quality Data Tables
The tables on the following pages show
the contaminants Minneapolis found last
year or the most recent time there was
sampling for that contaminant. They also
show the levels of those contaminants and
the Environmental Protection Agency’s
limits. Substances that we tested for but
did not find are not included in the tables.
The City of Minneapolis samples for
some contaminants less than once a year
because their levels in water are not
expected to change from year to year.
If we found any of these contaminants
the last time we sampled for them,
we included them in the tables with
the detection date.
The City of Minneapolis may have done
additional monitoring for contaminants
that are not included in the Safe Drinking
Water Act. To request a copy of these
results, call the Minnesota Department of
Health at 651-201-4700 or 1-800-818-9318
between 8 a.m. and 4:30 p.m. Monday
through Friday.
Definitions
AL (Action Level): The concentration of a
contaminant which, if exceeded, triggers
treatment or other requirements which a
water system must follow.
EPA: Environmental Protection Agency
MCL (Maximum contaminant level): The
highest level of a contaminant that is
allowed in drinking water. MCLs are set as
close to the MCLGs as feasible using the
best available treatment technology.
MCLG (Maximum contaminant level goal):
The level of a contaminant in drinking
water below which there is no known or
expected risk to health. MCLGs allow for a
margin of safety.
MRDL (Maximum residual disinfectant
level): The highest level of a disinfectant
allowed in drinking water. There is
convincing evidence that the addition of
a disinfectant is necessary for control of
microbial contaminants.
MRDLG (Maximum residual disinfectant
level goal): The level of a drinking water
disinfectant below which there is no
known or expected risk to health. MRDLGs
do not reflect the benefits of the use
of disinfectants to control microbial
contaminants.
N/A (Not applicable): Does not apply.
NTU (Nephelometric Turbidity Units): A
measure of the cloudiness of the water
(turbidity).

ppb (parts per billion): One part per
billion in water is like one drop in one
billion drops of water, or about one drop
in a swimming pool. ppb is the same as
micrograms per liter (μg/l).
ppm (parts per million): One part per
million is like one drop in one million
drops of water, or about one cup in a
swimming pool. ppm is the same as

Potential Health Effects and Corrective Actions (If Applicable)
Fluoride: Fluoride is nature’s cavity fighter,
with small amounts present naturally in
many drinking water sources. There is an
overwhelming weight of credible, peer-
reviewed, scientific evidence that fluoridation reduces tooth decay and cavities in children
and adults, even when there is availability
of fluoride from other sources, such as
fluoride toothpaste and mouth rinses. Since studies show that optimal fluoride levels in drinking water benefit public health,
municipal community water systems adjust the level of fluoride in the water to an optimal
concentration between 0.5 to 0.9 parts per
million (ppm) to protect your teeth. Fluoride
levels below 2.0 ppm are not expected to increase the risk of a cosmetic condition known as enamel fluorosis.

Monitoring Results –
Unregulated Substances
In addition to testing drinking water for
contaminants regulated under the Safe
Drinking Water Act, we sometimes also
monitor for contaminants that are not
regulated. Unregulated contaminants do
not have legal limits for drinking water.
Detection alone of a regulated or
unregulated contaminant should not cause
concern. The meaning of a detection
should be determined considering current
health effects information. We are often
still learning about the health effects, so
this information can change over time.
The following table shows the unregulated
contaminants we detected last year, as
well as guidance values for comparison,
where available. The comparison values
are based only on potential health
impacts to people and do not consider
our ability to measure contaminants
at very low concentrations or the cost
and technology of prevention and/or
treatment. They may be set at levels that
are costly, challenging or impossible for
water systems to meet (for example,
large-scale treatment technology may
not exist for a given contaminant).
A person drinking water with a
contaminant at or below the comparison
value would be at little or no risk for
harmful health effects. If the level of a
contaminant is above the comparison
value, people of a certain age or with
special health conditions – like pregnant
women, infants, children, elderly, and
people with impaired immunity – may
need to take extra precautions. Because
these contaminants are unregulated,
EPA and MDH require no particular
action based on detection of an
unregulated contaminant. We are
notifying you of the unregulated
contaminants we have detected as
a public education opportunity.

Some People Are More Vulnerable to
Contaminants in Drinking Water
Some people may be more vulnerable to
contaminants in drinking water than the
general population. Immuno-compromised
people such as those with cancer
undergoing chemotherapy, those who
have undergone organ transplants, those
with HIV/AIDS or other immune system
disorders, some elderly and infants can
be particularly at risk from infections. The
developing fetus and therefore pregnant
women may also be more vulnerable to
contaminants in drinking water. These
people or their caregivers should seek
advice about drinking water from their
health care providers. EPA/Centers for
Disease Control (CDC) guidelines on
appropriate means to lessen the risk of
infection by Cryptosporidium and other
microbial contaminants are available
from the Safe Drinking Water Hotline
at 1-800-426-4791.

Drinking Water Sources
Minnesota’s primary drinking water
sources are groundwater and surface
water. Groundwater is the water found
in aquifers beneath the surface of the
land. Groundwater supplies 75 percent of
Minnesota’s drinking water. Surface water
is the water in lakes, rivers and streams
above the surface of the land. Surface
water supplies 25 percent of Minnesota’s
drinking water.
Contaminants can get in drinking water
sources from the natural environment and
from people’s daily activities. There are
five main types of contaminants in drinking
water sources.
• Microbial contaminants, such as
viruses, bacteria and parasites. Sources
include sewage treatment plants,
septic systems, agricultural livestock
operations, pets and wildlife.
• Inorganic contaminants include salts and
metals from natural sources (e.g. rock and
soil), oil and gas production, mining and
farming operations, urban stormwater
runoff and wastewater discharges.
• Pesticides and herbicides are chemicals
used to reduce or kill unwanted plants
and pests. Sources include agriculture,
urban stormwater runoff and
commercial and residential properties.
• Organic chemical contaminants
include synthetic and volatile organic
compounds. Sources include industrial
processes and petroleum production,
gas stations, urban stormwater runoff
and septic systems.
• Radioactive contaminants such as
radium, thorium and uranium isotopes
come from natural sources (e.g.
radon gas from soils and rock), mining
operations, and oil and gas production.
The Minnesota Department of Health
provides information about your drinking
water source(s) in a source water
assessment, including:
• How Edina is protecting your drinking
water source(s);
• Nearby threats to your drinking
water source(s);
• How easily water and pollution can
move from the surface of the land
into drinking water sources, based
on natural geology and the way
wells are constructed.
Find your source water assessment at
www.health.state.mn.us/communities/
environment/water/swp/swa or call

Lead in Drinking Water
You may be in contact with lead through
paint, water, dust, soil, food, hobbies or
your job. Coming in contact with lead
can cause serious health problems for
everyone. There is no safe level of lead.
Babies, children under 6 years, and
pregnant women are at the highest risk.
Lead is rarely in a drinking water source,
but it can get in your drinking water as
it passes through lead service lines and
your household plumbing system. Edina
is responsible for providing high quality
drinking water, but it cannot control
the plumbing materials used in private
buildings.
Read below to learn how you can protect
yourself from lead in drinking water.
1. Let the water run for 30-60 seconds
before using it for drinking or cooking
if the water has not been turned on
in over six hours. If you have a lead
service line, you may need to let the
water run longer. Service lines are
underground pipes that bring water
from the main water pipe under the
street to your home.
• You can find out if you have a lead
service line by contacting your public
water system or you can check by
following the steps at www.mprnews.
org/story/2016/06/24/npr-find-lead-
pipes-in-your-home.

• The only way to know if lead has been
reduced by letting it run is to check
with a test. If letting the water run
does not reduce lead, consider other
options to reduce your exposure.
2. Use cold water for drinking, making
food and making baby formula. Hot
water releases more lead from pipes
than cold water.
3. Test your water. In most cases, letting
the water run and using cold water for
drinking and cooking should keep lead
levels low in your drinking water. If you
are still concerned about lead, arrange
with a laboratory to test your tap
water. Testing your water is important
if young children or pregnant women
drink your tap water.
• Contact a Minnesota Department
of Health accredited laboratory
to get a sample container and
instructions on how to submit
a sample. Learn more at
https://eldo.web.health.state.mn.us/
public/accreditedlabs/labsearch.seam.
The Minnesota Department of
Health can help you understand
your test results.
4. Treat your water if a test shows your
water has high levels of lead after you
let the water run.
