2006 Drinking Water Consumer Confidence Report

Why Utility Co., Inc. is committed to providing its customers with a safe and reliable supply of drinking water. We are required under EPA/ADEQ rules to take scheduled water samples. These samples are tested by State Certified laboratories to check for various forms of chemical and biological contamination. This annual report, required by the Safe Drinking Water Act, tells you where your water comes from, what it contains, and other general information you should know about your drinking water.

The water supplied to customers of the Why Utility Company is pumped from two wells located at the comer of Ball Road and Mesquite Lane in the community of Why, Arizona. It is groundwater and is pumped from a depth of 809 feet.

Testing Requirements: The Company is required to collect one sample each month, which is tested for microbiological contamination. These samples are collected from a different location in the community each month, a total of 12 each year. We also test for inorganic compounds and volatile organic compounds on a schedule set by ADEQ. We also test for other contaminants as required. These tests were completed by Legend Technical Services of Arizona, Inc. for the current year. We have received monitoring waivers for Synthetic Organic Compounds due to the fact that previous testing showed no detects of any of these compounds.

Health Information: Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. If you are caring for an infant, you should ask for advice from your health care provider. (Our highest nitrate level was 3.88ppm.)

To ensure that tap water is safe to drink, EPA prescribes limits on the amount of certain contaminants in water supplied by public water systems. Drinking water, including bottled water, may reasonable 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 may be obtained by calling the EPA's Safe Drinking Water Hotline at 800-426-4971.

Some people may be more vulnerable to contaminants in drinking water than is the general population. Immuno-comprised 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 are available from the Safe Drinking Water Hotline.

As previously noted, our source of tap water is two deep wells. As water travels 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 which limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

Explanation of the Water Quality Data Table - Below, we have listed sample results taken during 2006. Samples taken 12-12-05 for year 2006.

Maximum Contaminant Level or MCL: the highest level of a contaminant that is allowed in drinking water.

Ppm - Parts per million, or milligrams per liter (mg/l) MCL and Results are in Ppm.
