2006 WATER QUALITY REPORT
FOR
CITY OF ROLAND

This report contains important information regarding the water quality in our water system. The source of our water is groundwater. Our groundwater is drawn from the Mississippian aquifer.

Our water quality testing shows the following results:

Note: Contaminants with dates indicate results from the most recent testing done in accordance with regulations. 

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.

• 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.

• ppb -- parts per billion.

• ppm -- parts per million.

• pCi/L – picocuries per liter

• N/A – Not applicable

• ND -- Not detected

• Action Level (AL) – The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

• EPA – Environmental Protection Agency

• CDC – Center for Disease Control

• RAA – Running Annual Average

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).

 SOURCE WATER ASSESSMENT INFORMATION

The City of Roland water supply obtains its water from the Mississippian aquifer.  The Mississippian aquifer was determined to be slightly susceptible to contamination because the characteristics of the aquifer and overlying materials limit the rate at which contaminants can move through the aquifer.  The wells will somewhat susceptible to activities such as dry cleaners, gas stations, industrial sites, and municipal wastewater dischargers.  A detailed evaluation of your source water was completed by the IDNR, and is available from Water/Wastewater Superintendent Dean Uitermark at (515) 388-4861.
