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.

·         SGL – Single Sample Result

·         RTCR – Revised Total Coliform Rule

·         NTU – Nephelometric Turbidity Units

 

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 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 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
