This report covers the drinking water quality for the Village of Deckerville for the 2022 calendar
year. This information is a snapshot of the quality of the water that we provided to you in 2022.
Included are details about where your water comes from, what it contains, and how it compares to
United States Environmental Protection Agency (U.S. EPA) and state standards.
Your water comes
from 3 groundwater wells, each 130 feet deep. The State performed an assessment of our source
water to determine the susceptibility or the relative potential of contamination. The susceptibility
rating is on a seven-tiered scale from “very-low” to “very-high” based on geologic sensitivity, well
construction, water chemistry and contamination sources. The susceptibility of our source is
Moderately Low
.
There are no significant sources of contamination in our water supply. We are making efforts to
protect our sources by participating in the wellhead protection program.
If you would like to know more about this report, please contact

Contaminants and their presence in 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 U.S. EPA’s Safe Drinking
Water Hotline (800-426-4791).
Vulnerability of sub-populations:
Some people may be more vulnerable to contaminants in
drinking water than the general population. Immuno-compromised persons such as persons with
cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/
AIDS or other immune systems disorders, some elderly, and infants can be particularly at risk from
infections. These people should seek advice about drinking water from their health care providers.
U.S. EPA/Center for Disease Control guidelines on appropriate means to lessen the risk of infection
by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water
Hotline (800-426-4791).
Sources of drinking water:
The sources of drinking water (both tap water and bottled water)
include rivers, lakes, streams, ponds, reservoirs, springs, and wells. Our water comes from 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 from human activity.
Contaminants that may be present in source water include:
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
, which may come from a variety of sources such as agriculture and
residential uses.
Radioactive contaminants
, which can be naturally occurring or be the result of oil and gas
production and mining activities.
Organic chemical contaminants
, including synthetic and volatile organic chemicals, which are
by-products of industrial processes and petroleum production, and can also come from gas stations,
urban stormwater runoff, and septic systems.
To ensure that tap water is safe to drink, the U.S. EPA prescribes regulations
that limit the levels of certain contaminants in water provided by public water
systems. Federal Food and Drug Administration regulations establish limits for
contaminants in bottled water which provide the same protection for public health.
1. Water Quality Data
The table below lists all the drinking water contaminants that we detected during the 2021
calendar year. The presence of these contaminants in the water does not necessarily indicate
that the water poses a health risk. Unless otherwise noted, the data presented in this table is from
testing done January
1 through December 31, 2022. 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 the data is representative of the water quality,
but some are more than one year old.
Terms and abbreviations used below:
Maximum Contaminant Level Goal (MCLG):
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.
Maximum Contaminant Level (MCL):
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.
Maximum Residual Disinfectant Level (MRDL):
The highest level of a disinfectant allowed
in drinking water. There is convincing evidence that addition of a disinfectant is necessary for
control of microbial contaminants.
Maximum Residual Disinfectant Level Goal (MRDLG):
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.
Treatment Technique (TT):
A required process intended to reduce the level of a contaminant
in drinking water.
N/A:
Not applicable
TRACE:
detectable but too small to measure
ND:
not detectable at testing limit
ppm:
parts per million or milligrams per liter
ppb:
parts per billion or micrograms per liter
ppt:
parts per trillion or nanograms per liter
pCi/l:
picocuries per liter (a measure of radioactivity)
Action Level (AL):
The concentration of a contaminant which, if exceeded, triggers treatment
or other requirements that a water system must follow.
Level 1 Assessment:
A study of the water supply to identify potential problems and determine
(if possible) why total coliform bacteria have been found in our water system.
Level 2 Assessment:
A very detailed study of the water system to identify potential problems
and determine (if possible) why an E. coli MCL violation has occurred and/or why total coliform
bacteria have been found in our water system on multiple occasions.
Information about lead:
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. The
Village of Deckerville is responsible for providing high
quality drinking water but cannot control the variety of
materials used in plumbing components. When your
water has been sitting for several hours, you can minimize
the potential for lead exposure by flushing your tap for 30
seconds to 2 minutes before using water for drinking or
cooking. If you have a lead service line it is recommended
that you run your water for at least 5 minutes to flush
water from both your home plumbing and the lead service
line. If you are concerned about lead in your water, you
may wish to have your water tested. Information on lead
in drinking water, testing methods, and steps you can take
to minimize exposure is available from the Safe Drinking
Water Hotline or at http://www.epa.gov/safewater/lead.
Monitoring and Reporting to the Department of
Environment, Great Lakes, and Energy (EGLE) Requirements:
The State of Michigan and the U.S. EPA require us to
test our water on a regular basis to ensure its safety.
Possible health effects are: Reproductive effects such
as decreased fertility or increased high blood pressure
in pregnant women. Developmental effects or delays in
children, including low birth weight, accelerated puberty,
bone variations, or behavioral changes. Increased risk of
some cancers, including prostate, kidney, and testicular
cancers. Reduced ability of the body’s immune system
to fight infections, including reduced vaccine response.
Interference with the body’s natural hormones. Increased
cholesterol levels and/or risk of obesity.
We will update this report annually and will keep you
informed of any problems that may occur throughout the
year, as they happen. Copies are available at the Village
Office, 2521 Black River St. This report will not be sent
to you.
We invite public participation in decisions that affect
drinking water quality. Village Council meetings are held
the 2nd Monday of the month at 2521 Black River St.
in the Village Council Chambers. For more information
about your water, or the contents of this report, contact
Tracy Hoff, 810-376-8591 or visit www.deckerville.us. For
