Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium for microbial growth. Turbidity may
indicate the presence of disease-causing organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such
as nausea, cramps, diarrhea and associated headaches.

These tables are based on tests conducted by GLWA in the year 2020 or the most recent testing done within the last five calendar years.
GLWA conducts tests throughout the year only tests that show the presence of a substance or require special monitoring are presented in
these tables. The State allows us to monitor for certain contaminants less than once per year because the concentrations of these
contaminants are not expected to vary significantly from year to year. All of the data is representative of the water quality, but some are more
than one year old.

Where does Clinton Township get its drinking water?
Clinton Township receives its water supply from the
Great Lakes Water Authority (GLWA) and the City of
Mount Clemens. Our source water from the GLWA
comes from the lower Lake Huron watershed and the
Detroit River. Source water from Mount Clemens
comes from Lake St. Clair.
The Lake Huron watershed includes numerous short,
seasonal streams that drain to Lake Huron. Source
water from the Detroit River comes from Lake St. Clair,
Clinton River, Detroit River, Ecorse River, in the U.S.
and parts of the Thames River, Little River, Turkey
Creek and Sydenham watershed in Canada.

Unregulated contaminants are those for which the EPA has not established drinking water
standards. Monitoring helps the EPA to determine where these contaminants occur and whether it
needs to regulate them. On page 4, see the report of unregulated contaminants detected during
quarterly sampling and analysis performed in 2015 and 2018.
Clinton Township tested a wide variety of unregulated contaminants during 2015, 2018 and 2019.
The unregulated contaminant tests are available to customers by contacting the Clinton Township
Water Department at 586-286-9300.

Concerned about lead in your water?
If present, elevated levels of lead can cause serious
health problems, especially for pregnant women and
young children. Lead in drinking water is primarily from
materials and components associated with service lines
and home plumbing. Clinton Township is responsible
for providing high quality drinking water, but cannot

*The 90th percentile value means 90 percent of homes tested have lead and copper levels below the given 90th percentile value. If the 90th
percentile value is above AL, additional requirements must be met.

Preliminary distribution system materials inventory
The primary focus of the preliminary Distribution System Materials Inventory (DSMI) is to identify lead service lines, galvanized
steel previously connected to lead, or service lines of unknown material. This inventory will estimate the number of high-risk
service lines and describe the reliability of existing records, thereby providing important information for planning service line
verification and replacement efforts. The complete DSMI, which is due in 2025, will require characterization of all service line
materials (lead, galvanized, copper, and plastic).
          The number of service lines found to be lead = 0.
          The number of service lines that need to be investigated for materials = 19,880.
          The total number of service lines in Clinton Township = 28,448.
Sources of information used to summarize or estimate the data above include tap records and visual inspection and
maintenance records.

**Unregulated contaminants are those EPA has not established drinking water standards. Monitoring helps EPA determine where these
contaminants occur and whether regulation of those contaminants is needed. The City of Mount Clemens tested a wide variety of unregulated
contaminants in 2020. Theses tests are available to customers by contacting the Mount Clemens Utilities Department.

Frequently asked questions about your sewer issues
Whose sewer is it?
The Water and Sewer Dept. cleans and maintains the mainline sanitary sewers generally located within a public right
-of-way. As a rule, these sanitary sewers are 10 inches or larger in diameter. The sanitary sewer lateral pipe from
your house to the mainline is generally six inches in diameter. The lateral pipe is installed and maintained by the
homeowner as per the codified ordinances of the Township.

What should I do when my sewer is backing up?
Call the Water and Sewer Dept. at one of the following: Clinton Twp. Main Office 586-286-9300, weekdays, 8:30
a.m. to 4:30 p.m. Shook Road Maintenance Facility 586-791-1766, weekdays, 7 a.m. to 3:30 p.m. After Hours
Emergency Number 586-469-5502 (a police dispatch operator will answer). A representative of the Water and Sewer
Dept. will respond as soon as possible by visiting the site to determine if the problem is the responsibility of the
Township or the homeowner. The department offers 24-hour, on-call service, with no service fee. ALL WATER AND
SEWER DEPARTMENT EMPLOYEES CARRY PICTURE IDENTIFICATION.

Who do I call to clean my sanitary sewer lateral pipe?
We recommend you contact three contractors to compare prices. Ask each for a minimum estimate, including how
many feet of cleaning is done, and a price per additional foot. Ask about a warranty, for how long, and what does it
include. If one price is much lower than the others, ask for references, or check with the Better Business Bureau.
Once the contractor opens your drain, ask to have it cleaned with the largest cleaning tool that can be safely used.
CLINTON TOWNSHIP IS NOT ABLE TO ENDORSE OR RECOMMEND ANY DRAIN CLEANING SERVICES.

damaged or needs replacement?
We suggest you hire a drain cleaning contractor, who can insert a closed circuit television camera into the sanitary
lateral to locate and identify any problems. This first step is a less costly alternative in cleaning your sewer lateral
before any excavation for repairs. Contractors who provide this service are listed online or in phone directories. If
your sanitary sewer lateral needs replacement, be advised that the contractor you hire must register with the
Clinton Township Water and Sewer Department. Not all drain cleaning contractors are registered to repair and
install sanitary sewer laterals. Registered contractors must meet certain standards, have proper insurances and post
a bond covering their work. We recommend you contact three contractors to compare prices.

My basement flooded, what should I do?
During and following a flood, contact your utility companies for advice
and information on precautions and safety measures. Do not handle
connected electrical cords or appliances if the electrical current is still
on. Do not light a flame in an enclosed area containing gas or oil-fired
appliances. If your appliance's electrical controls are submerged, do
not attempt to re-start the unit until you have consulted with a
qualified service provider.

How do I clean and disinfect after a flood?
Begin by providing as much ventilation as possible. Open windows,
doors and run fans to allow moist air to escape. You should disinfect
anything that has been in contact with flood waters. Clean walls and floors with a mixture of household detergent
and water, using a scrub brush with stiff bristles. Disinfect surfaces with a chlorine solution rinse made up of eight
tablespoons (1/2 cup) common household bleach per gallon of clean, warm water. Chlorine bleach is an effective
disinfectant, but should never be mixed with ammonia, since this combination produces poisonous gas. Professional
cleaning services are listed online under fire and water damage restoration.

What items can I salvage after a flood?
All hard-surfaced items such as storage containers, metal boxes, plastic toys, etc., should be thoroughly washed in
soap and warm water and disinfected in a chlorine solution. Stuffed and upholstered furniture, mattresses, plush
toys, and similar items are often impossible to decontaminate and clean with a conventional liquid or spray type
germicide. If you choose to salvage, consult online or phone directories for services specializing in furniture, carpet
and upholstery cleaning. Discard all non-hermetically sealed fruits, vegetables and stored food items that were in
direct contact with flood waters. Jars, bottles and similar containers with crimped or screw-on caps, lids or covers, as
well as cork or paraffin tops, may not safely prevent product contamination. Hermetically sealed, vacuum or
pressure-packed foods can be salvaged by thoroughly washing the exterior surfaces with detergent and hot water,
followed by immersion in a chlorine solution for at least 15 minutes.

What about my hygiene before, during, and after clean up?
Protect yourself by wearing rubber gloves during clean up, and wash your hands frequently in warm chlorinated
water before eating. Use care to prevent tracking sewage and contaminated floodwaters into areas of your home
that are clean. Wash clothing at the end of the day, and take a hot shower.

 Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic
 systems, agricultural livestock operations, and wildlife.
 Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban
 stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
 Pesticides and herbicides can come from a variety of sources such as agriculture, urban stormwater runoff, and
 residential uses.
 Organic chemical contaminants, including synthetic and volatile organics, are by-products of industrial processes
 and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.

 426-4791.
 The sources of drinking water (both tap water and
 bottled water) include rivers, lakes, streams, ponds,
 reservoirs, springs, and wells. As water travels over the
 surface of the land or through the ground, it dissolves
 naturally-occurring minerals and, in some cases,
 radioactive material, and can pick up substances
 resulting from the presence of animals or human
 activity.

 Frequent questions related to Coronavirus (COVID-19)
Is drinking tap water safe?
The EPA recommends that Americans continue to use and drink tap water as usual. The World Health Organization
(WHO) has stated that the, “presence of the COVID-19 virus has not been detected in drinking-water supplies and
based on current evidence the risk to water supplies is low.” Additionally, according to the CDC, COVID-19
is mainly thought to spread between people who are in close contact with one another. Further, EPA’s drinking
water regulations require treatment at public water systems to remove or kill pathogens, including viruses.
World Health Organization. 2020. Technical Brief. Water, sanitation, hygiene and waste management for the COVID-19 virus. March.

Do I need to buy bottled water or store drinking water?
The EPA recommends that citizens continue to use and drink tap water as usual. At this time, there are no
indications that COVID-19 is in the drinking water supply or will affect the reliable supply of water.

Is tap water safe to use for hand washing?
The EPA recommends that Americans continue to use and drink tap
water as usual. According to the CDC, washing your hands often with
soap and water for at least 20 seconds helps prevent the spread of
COVID-19.

Do I need to boil my drinking water?
Boiling your water is not required as a precaution against COVID-19.
