WORK SESSION STAFF REPORT
Work Session Item No. 1
Date: January 6, 2020
To: City Council
From: Rick DeGardner, Public Services Director
Greg Johnson, WSB and Associates
Re: Public Water System - Manganese Test Results (UCMR4)
Background
The U.S. Environmental Protection Agency’s (EPA) sets safe drinking water standards. There
are primary standards and secondary standards. The primary standards are regulated through
Maximum Contaminate Levels (MCL). Testing by the Minnesota Department of Health (MDH)
shows the City’s municipal water supply continues to meet all Safe Drinking Water Act
standards.
The Safe Drinking Water Act requires that every five years secondary unregulated contaminants
are evaluated. As a result the EPA issues a new list of 30 unregulated contaminants to be
monitored by Public Water Systems (PWSs). The Unregulated Contaminant Monitoring Rule
(UCMR) provides the EPA and other interested parties with scientifically valid data on the
occurrence of contaminants in drinking water. This national survey is one of the primary sources
of information on occurrence and levels of exposure that EPA uses to develop regulatory
decisions for contaminants in the public drinking water supply.
UCMR4 monitoring is currently occurring thru 2020 and includes manganese, which was not
previously identified to cause health effects. Developing research, reviewed by the MDH
indicates that children and adults who drink water with high levels of manganese for an extended
period time may have problems with memory, attention, and motor skills. Infants (babies under
one year old) may develop learning and behavior problems if they drink water with too much
manganese in it. Although MDH tested manganese levels in municipal water systems state-wide
in 2011, the effects of manganese were not clearly understood or published until additional
research was recently completed by MDH. The attached MDH fact sheet provides additional
information:
▪ If you have an infant who drinks tap water or drinks formula made with tap water, a safe level
of manganese in your water is 100 micrograms of manganese per liter of water (μg/L)* or less.
▪ If you have an infant who never drinks tap water or formula made with tap water, a safe level
of manganese in your water is 300 μg/L or less.
▪ If everyone in your household is more than one year old, a safe level of manganese in your
water is 300 μg/L or less.
City of Lino Lakes received the attached letter from the MDH regarding UCMR4 as it relates to
the City’s drinking water. The City’s Well Nos. 3 and 4 were randomly selected by EPA to be
tested and monitored by MDH under UCMR4. The test results from MDH, Well No. 3 contains
367 micrograms of manganese per liter of water (μg/L), and Well No. 4 contains 82.7 μg/L (1
μg/L = 1 Part Per Billion (PPB)). The City requested additional testing from MDH to obtain a
uniform baseline of data.
The December 31, 2019 MDH test results for all the City’s wells:
City Well Number
Manganese
Concentration
(micrograms per
liter)
1 158
2 527
3 322
4 84
5 143
6 408
MDH requires the test results from the UCMR4 monitoring to be published in a public water
system’s annual Consumer Confidence Report (CCR) also referenced as the Drinking Water
Report.
The City is working with engineering consultants and MDH professionals on short-, mid-, and
long-term plans to reduce the manganese levels in the City’s municipal drinking water.
Short Term Solution- the City has reduced the manganese levels in the water supply by limiting
the use of wells with high manganese levels. While this practice has lowered the manganese
levels to below 300 ppb, a level that is safe for adult and child consumption, it is still
recommended to consider bottled water for formula fed infants under the age of 12 months. The
City is in the process of sending out informational letters to households and businesses that
currently use the municipal water supply, and properties with private wells. The City also plans
to hold a public informational meeting at 6:00 pm on Wednesday, January 22, 2020.
Mid and Long Term Solutions- are being evaluated to permanently reduce the levels of
manganese in drinking water. These options include:
• Modifying the existing watering ban ordinance
• Utilizing water from neighboring municipal water systems
• Drilling new wells
• Constructing a water treatment plant
During the summer months, the demand for water will increase, resulting in the need to use
water from additional wells. This will likely increase manganese levels and at that time all
residents may want to take additional actions to protect their health.
Recommended Actions
There are several things you can do to filter manganese out of your drinking water. Certain types
of home water treatment units remove or reduce manganese (refrigerator water filter, pour-
through pitchers, units that attach to faucet, water softeners, etc.). Minnesota Department of
Health’s website: www.health.state.mn.us and search Home Water Treatment for details.
If you do not have a home water treatment device that removes or reduces manganese, you may
want to consider installing one or using bottled water that is labeled as “distilled” or “purified”
for drinking, cooking, and preparing infant formula.
Private Well Owners - Some Minnesota groundwater naturally has levels of manganese higher
than the MDH guidance values. Homeowners with private wells are responsible for having their
wells tested. Learn more on the Minnesota Department of Health’s website:
www.health.state.mn.us and search Owner’s Guide to Wells. The Anoka County Public Health
and Environmental Services (ACPHES) Department (www.anokacounty.us) accepts water
samples. The City offers free test kits that are available at Lino Lakes City Hall. ACPHES
charges a $15 to $30 lab fee at the time of processing.
Requested Council Direction
Consider a Water Supply and Treatment Feasibility Study at a future City Council work session.

Manganese in Drinking Water
Manganese occurs naturally in rocks and soil across Minnesota and is often found in Minnesota
ground and surface water. Your body needs some manganese to stay healthy, but too much can be
harmful.
Health Effects
Children and adults who drink water with high
levels of manganese for a long time may have
problems with memory, attention, and motor
skills. Infants (babies under one year old) may
develop learning and behavior problems if they
drink water with too much manganese in it.
How to Protect Yourself & Your Family
The Minnesota Department of Health (MDH)
developed guidance values to keep your
household drinking water safe. Because these are
guidance values, public water systems are not
required to meet these values and some do not.
▪ If you have an infant who drinks tap water or
drinks formula made with tap water, a safe level
of manganese in your water is 100 micrograms
of manganese per liter of water (µg/L)* or less.
▪ If you have an infant who never drinks tap water
or formula made with tap water, a safe level of
manganese in your water is 300 µg/L or less.
▪ If everyone in your household is more than one
year old, a safe level of manganese in your
water is 300 µg/L or less.
Drinking water with a level of manganese above
the MDH guidance level can be harmful for your
health, but taking a bath or a shower in it is not.
Manganese in your water can stain your laundry,
cause scaling on your plumbing, and make your
water look, smell, or taste bad. Manganese can
also create a brownish-black or black stain on
your toilet, shower, bathtub, or sink.
The only way to know the level of manganese in
your drinking water is to contact your public
water system or have your tap water tested. All
water testing should be done through an
accredited laboratory. Contact an accredited
laboratory to get sample containers and
instructions, or ask your county environmental or
public health services if they provide water testing
services (see Search for Accredited Laboratories).
If you have a household water treatment unit, the
unit may reduce the level of manganese in your
drinking water (see Home Water Treatment Units:
Point-of-Use Devices for more information). MDH
and Dakota County conducted at study in 2016
and found that water softeners can be an
effective way to reduce the level of manganese in
drinking water (see The Wells and Increased Infant
Sensitivity and Exposure (WIISE) Study).
*One microgram per liter (µg/L) is the same as 1
part per billion.
If you have a private well
Some Minnesota groundwater naturally has levels
of manganese higher than the MDH guidance
values. You may want to test your drinking water
for manganese, especially if infants drink your tap
water. You are responsible for keeping your well
water safe and testing it as needed.
If you are on a public water system
Public water systems may test their water for
manganese, but they are not required to. You can
contact your public water system to find out if
they test the water for manganese. If your public
water system does not test for manganese, you
can arrange and pay for an accredited laboratory
to test your water. Remember that certain types
of home water treatment units may make the
level of manganese lower in your tap water than
what your water system detected.
MANGANESE IN DRINKING WATER
2
Background Information
Manganese occurs naturally in rocks and soil and
can be found in water, food, and air. Your body
needs some manganese to stay healthy. The
recommended daily intake for manganese
depends on a person's age and sex. The
recommended manganese intake for children
over eight years old and adults varies from 1,900
to 2,600 µg per day. Infants should consume 600
µg or less of manganese per day.
The level at which manganese benefits one
person could overlap with the level at which it is
harmful to another person. Adults and children
get enough manganese through their diet. Infants
get enough manganese from breast-milk, food, or
formula. Food often has a higher manganese level
than water; however, there are many types of
food that can actually block manganese from
getting into the body. Water does not have the
same characteristics as food, so your body can
more easily absorb manganese in water.
Manganese in Minnesota’s Water
Manganese occurs naturally in groundwater
across Minnesota. Based on an MDH study,
groundwater in southeastern Minnesota tends to
have low levels of manganese (below 50 µg/L).
Southwestern Minnesota tends to have higher
levels—some over 1,000 µg/L. There are no clear
patterns in the other parts of the state.
Although public water systems are not required to
test for manganese, some Minnesota community
public water systems test for manganese either
before or after treating water. Based on test
results and treatment practices, MDH estimates
about 90 percent of Minnesotans using
community public drinking water systems receive
water with levels of manganese below 100 µg/L.
About 3 percent of Minnesotans on community
public water systems receive water with levels
above 300 µg/L. It is important to remember
certain types of household water treatment units
may reduce manganese to safe levels.
What MDH is Doing
MDH has health-based guidance for manganese in
water (see Human Health-Based Water Guidance
Table). MDH gathered data to find patterns of
where manganese occurs in Minnesota’s
groundwater (see Initial Assessment of Manganese
in Minnesota Groundwater). MDH also participated
in an effort by the Minnesota Ground Water
Association to create a report about manganese
called Manganese in Minnesota’s Groundwaters.
What Other Groups are Doing
Researchers at the University of Minnesota
received funding to investigate Risks to Infants
from Manganese in Drinking Water.

City Hall: 651-982-2400 – www.ci.lino-lakes.mn.us
Dear Residents,
Every Lino Lakes resident is receiving this letter to notify users of a consumption advisory regarding the municipal
water supply. This notice affects approximately 5,000 households and businesses that currently use the municipal
water supply. In addition, the nearly 1,500 properties with private wells may be affected.
The City is dedicated to providing clean and safe drinking water to residents. Testing by the Minnesota
Department of Health (MDH) shows the City’s municipal water supply continues to meet all Safe Drinking Water
Act standards.
MDH conducted additional testing in 2019 as part of a study of unregulated contaminants. This testing showed
that some of our wells have manganese levels above MDH’s recommended health guidelines.
The Issue: Manganese
Manganese is a naturally occurring element found in rocks and soil and is often found in Minnesota ground and
surface water. Your body needs some manganese to stay healthy, but too much can be harmful. Learn more by
visiting the MDH webpage at www.health.state.mn.us and searching for Manganese in Drinking Water.
Manganese is unregulated and does not have an enforceable standard. However, the MDH recommended health
guidelines are:
1) If you have an infant who drinks tap water or drinks formula made with tap water, a safe level of
manganese in your water is 100 parts per billion (ppb) or less.
2) If you have an infant who never drinks tap water or formula made with tap water, a safe level of
manganese in your water is 300 ppb or less.
3) If everyone is more than one year old, a safe level of manganese in your water is 300 ppb or less.
The City requested testing from MDH to better understand manganese levels for all City wells. The most recent
results are as follows:
Well #1 158 ppb Well #4 84 ppb
Well #2 527 ppb Well #5 143 ppb
Well #3 322 ppb Well #6 408 ppb
The City’s municipal water supply is a mixture of water from all six wells. The water mixes in water mains and
towers, and then travels to customers’ taps. The City cannot know the level of manganese at any given drinking
water tap.
