The presence of contaminants does not necessarily indicate that the water poses a health risk. More <br />information about contaminants and potential health effects can be obtained by calling the USEPA's Safe Drinking <br />Water Hotline (1-800-426-4791). Some people may be more vulnerable to contaminants in drinking water than the <br />general population. lmmuno-compromised persons such as persons with cancer undergoing chemotherapy, persons <br />who have undergone organ transplants, people with NV/AIDS or other immune system disorders, some elderly, and <br />infants can be particularly at risk from infections. These people should seek advice about drinking water from their <br />health care providers. <br />While your drinking water meets the current EPA standard for arsenic, it does contain low levels of arsenic, The <br />arsenic standard balances the current understanding of arsenic's possible health effects against the cost of removing <br />arsenic from drinking water. The U.S. Environmental Protection Agency continues to research the health effects of <br />low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to <br />other health effects such as skin damage and circulatory problems. <br />Vulnerability Assessment Summary <br />A source water assessment was conducted for the main well of the French Camp RV Park and Golf Course water <br />system in May of 2002. The source is considered most vulnerable to the following activities not associated with any <br />detected contaminants: chemical/petroleum processing/storage, injection wells/dry well known contaminant plumes. landfills/damps, mining operations - historic, septic systems - high density, underground injection of commercial/industrial discharges, and underground storage tanks - confirmed leaking tanks. The source is considered <br />vulnerable to activities located near the drinking water source.
