We’re pleased to present to you the 1999 Annual Water Quality Report.  This report is designed to inform you about the quality water and services we deliver to you every day.  Our constant goal is to provide you with a safe and dependable supply of drinking water.  We are committed to ensuring the quality of your water.

The source of our water is groundwater. Our groundwater is drawn from Cambrian Jordan Sandstone aquifer(s).  A source water assessment has been completed at this time.

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.

·         ppb -- parts per billion.

·         ppm -- parts per million.

·         pCi/L – picocuries per liter

·         N/A – Not applicable

·         ND -- Not detected

·         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.

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).

CONTAMINANT VIOLATIONS

None.

ADDITIONAL HEALTH INFORMATION

Infants and young children are typically more vulnerable to lead in drinking water than the general population.  It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home’s plumbing.  If you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested and flush your tap for 30 seconds to 2 minutes before using tap water.  Additional information is available from the Safe Drinking Water Hotline (800-426-4791).
