DEFINITIONS
·
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 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.
· ppb -- parts per billion.
· ppm -- parts per million.
· pCi/L picocuries per liter
· N/A Not applicable
· ND -- Not detected
·
RAA Running Annual Average
·
Treatment Technique (TT) A required process
intended to reduce the level of a contaminant in drinking water.
·
Action Level (AL)
The concentration of a contaminant which, if exceeded, triggers treatment or
other requirements which a water system must follow.
·
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.
·
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.

GENERAL INFORMATION
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 posed a health risk. More information about contaminants or
potential health effects can be obtained by calling the Environmental
Protection Agencys 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 system 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 Safe Drinking Water
Hotline (800-426-4791).
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. BODE MUNICIPAL WATER
SUPPLY 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 http://www.epa.gov/safewater/lead.
SOURCE WATER
ASSESSMENT INFORMATION
This water supply obtains its
water from the limestone and dolomite of the Mississippian-Devonian
aquifer. The Mississippian-Devonian
aquifer was determined to be susceptible to contamination because the
characteristics of the aquifer and overlying materials provide some protection
from contaminants from the land surface.
The Mississippian-Devonian well will be susceptible to surface
contaminants such as leaking underground storage tanks, contaminant spills, and
excess fertilizer application. A
detailed evaluation of your source water was completed by the Iowa Department
of Natural Resources, and is available at City Hall 515-379-1486 or our Website
http://www.cityofbode.org
For
questions regarding this information or how you can get involved in decisions
regarding the water system, please contact City
Hall at 515-379-1486.
City
council meetings are held on the 1st Monday of each month at 5:30 pm
at City Hall and are open to the public.
Please
note: This report will not be mailed to individual customers.
