DEFINITIONS
Drinking water, i,ncluding 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 &00-426- 479 l).
Some people may be more vulnerable to contaminants in drinking water than the general population. Imma.no-compromised persons such as persons with cancer undergoing chemotherapy persons who haye 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 appwpriate means to lessen the ri.sk of infection by C1yptospo1·idium 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. CASCADE 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 ex-posure 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 ater testeg, lnformatio,n_on lead in clrinkil:lg water,testirig-methoMan.a steps you can take to

This water supply obtains its water from the sandstone and dolomite of the Cambrian-Ordovician aquifer. The Cambrian-Ordovician flquifer was determined to have low Slll>ceptibility to contamination because the characteristics of the aquifer and overlying materials provide natural protection from contaminants at the land surface. The Cambrian-Ordovician wells will have low susceptibility 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 from the Water Operator at 563-852-3114 .
