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 (800-426-4791).
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. EPA/CDC guidelines on appropriate means to lessen the
risk of infection by cryptosporidium and other microbial contaminants are
available from the Environmental Protection Agency's safe drinking water
hotline (800-426-4791).

To obtain a summary of the source water
assessment please contact, Sheldon R Donath at (715) 205-9393.
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
from human activity.
Contaminants that may be present in source
water include:
In order to ensure that tap water is safe to
drink, EPA prescribes regulations that limit the amount of certain contaminants
in water provided by public water systems. FDA regulations establish limits for
contaminants in bottled water, which shall provide the same protection for
public health.
Term |
Definition |
AL |
Action
Level: The concentration of a contaminant which, if exceeded, triggers
treatment or other requirements which a water system must follow. |
Level
1 Assessment |
A
Level 1 assessment is a study of the water system to identify potential
problems and determine, if possible, why total coliform bacteria have been
found in our water system. |
Level
2 Assessment |
A
Level 2 assessment is a very detailed study of the water system to identify
potential problems and determine, if possible, why an E. coli MCL violation
has occurred or why total coliform bacteria have been found in our water
system, or both, on multiple occasions. |
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. |
MFL |
million
fibers per liter |
MRDL |
Maximum
residual disinfectant level: 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. |
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. |

Technique: A required process intended to reduce the level of a contaminant
in drinking water. |
Your water was tested for many contaminants
last year. We are allowed to monitor for some contaminants less frequently than
once a year. The following tables list only those contaminants which were
detected in your water. If a contaminant was detected last year, it will appear
in the following tables without a sample date. If the contaminant was not
monitored last year, but was detected within the last 5 years, it will appear
in the tables below along with the sample date.

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. Clayton Waterworks 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 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 www.epa.gov/safewater/lead.
