Consumer Confidence Reports (Required by State of California Dept. of Health Services)

What the State of California wants you to know
California's Department of Public Health requires all public water systems to include the following information in their yearly consumer confidence report (CCR).

About drinking water - The sources of drinking water - both tap and bottled - include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or 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.

The following contaminants may be present in source water before it is treated.

  • Microbial contaminants such as viruses and bacteria from sewage treatment plants, septic systems, livestock operations, and wildlife.
  • Inorganic contaminants such as salts and metals that occur naturally or stem from urban stormwater runoff, industrial or domestic wastewater discharges,  oil and gas production, mining, and farming.
  • Pesticides and herbicides from sources such as agriculture, urban stormwater runoff, and residential uses.
  • Organic chemical contaminants such as synthetic and volatile organic chemicals that are byproducts of industrial processes and petroleum production or that come from gas stations, urban stormwater runoff, agricultural applications, and septic systems.
  • Radioactive contaminants that occur naturally or are the result of oil and gas production and mining.

To ensure that tap water is safe to drink the U.S. Environment Protection Agency and the California Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by public water systems.  Department regulations also establish limits for contaminants in bottled water that must provide the same protection for public health.

The State of California allows us to monitor for some contaminants less than once a year because the concentration of the contaminants do not change frequently.  Some of our data, although representative, may be more than a year old.

NOTE: 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 poses a health risk.  Contact the U.S. Environmental Protection Agency’s Safe Drinking Water Hotline at 1-800-426-4791 for more about contaminants and potential health effects.

The primary source of water for the Amador Water Agency is the Mokelumne River, which is supplied from rainfall and snow melt in the Sierra Nevada Mountains. Water from the Mokelumne River is stored in high mountain reservoirs, conveyed to Lake Tabeaud and the Tiger Creek Afterbay and diverted to AWA’s treatment plants.

Mokelumne River water is stored in Tiger Creek Afterbay and gravity fed to the PG&E Tiger Creek Powerhouse Memcor Plant where it is treated and serves the PG&E Conference Center.  Water from the Tiger Creek Afterbay is also pumped to the Buckhorn Water Treatment Plant where it is treated for use by the customers of Pine Grove, Pine Acres, Sunset Heights, Fairway Pines, Jackson Pines, Pioneer, Gayla Manor, Ponderosa Ridge, Ranch House Estates, Pine Park East, Toma Lane, Sierra Highlands, Silver Lake Pines, Ridgeway Pines, Rabb Park, and Mace Meadows. 

Water from the Mokelumne River is also stored in Lake Tabeaud and conveyed via the Amador Transmission Line to the Tanner Water Treatment Plant where it is treated for use by the customers of Jackson, Sutter Creek, Plymouth, Amador City, and Drytown.  The Ione Pipeline transports raw water from the Tanner Reservoir to the Ione Water Treatment Plant where it is treated for use by customers of Ione.

Other Sources

Our La Mel Heights customers get their water from two wells located in the La Mel Heights Subdivision and our Lake Camanche residents get their water from four wells located in the Lake Camanche area.
