About the Water Quality Report

The Water Quality Report is an annual summary of the results of ongoing tests for contaminants in drinking water. The report is designed to inform you of the quality of your drinking water. Each year, the State Water Resources Control Board (State Water Board) and U.S. Environmental Protection Agency (EPA) require EID to compile and distribute a report to all of our water customers. The report includes a comparison of the District’s water quality to state and federal standards.

EID maintains three water systems. The main water system runs from El Dorado Hills to Pollock Pines and encompasses the majority of our customers. The Outingdale system provides water from the Middle Fork of the Cosumnes River to 191 service accounts in the small community of Outingdale, approximately 15 miles southeast of Placerville. The Strawberry system provides water from the upper South Fork American River to 147 service accounts in the community of Strawberry located approximately 40 miles east of Placerville along Highway 50.

EID has rights to approximately 75,000 acre-feet of water from various sources in the Sierra Nevada foothills. (An acre-foot equals one acre of land covered by a foot of water; there are 325,851 gallons in an acre-foot.) Jenkinson Lake, at the center of Sly Park Recreation Area, provides nearly one half of our Main System's water supply. Forebay Reservoir in Pollock Pines delivers water under a pre-1914 water right from the high-alpine streams and lakes that are part of our Project 184 hydropower system. We have a water contract with the Bureau of Reclamation at Folsom Lake, which Reclamation operates as part of the state’s Central Valley Water Project. And we hold ditch water rights (Weber, Slab, and Hangtown creeks), water rights at Weber Reservoir, and a water right under Permit 21112 for Project 184 water—all of which is delivered from Folsom Lake.

Information About Potential Sources of Pollution

The State Water Board requires water providers to conduct a source water assessment to help protect the quality of water supplies. The assessment describes where a water system’s drinking water comes from, the types of polluting activities that may threaten the quality of the source water, and an evaluation of the water’s vulnerability to the threats.

Updated assessments of EID’s drinking water sources were completed in 2006, 2008, and 2013. Our source water is considered most vulnerable to recreation, residential sewer, septic system, and urban runoff activities, which are associated with constituents detected in the water supply. Our source water is also considered most vulnerable to illegal activities, dumping, fertilizer, pesticide and herbicide application, forest activities, and wildfires, although constituents associated with these activities were not detected. constituents associated with these activities were not detected. Copies of the assessments are available at the State Water Resources Control Board, Division of Drinking Water, P.O. Box 997377, Sacramento, CA 95899-7377. To view them, contact Ali Rezvani, DDW Sacramento District Engineer, at 916-445-5285, or Dana Strahan, EID Drinking Water Division Operations Manager, at 530-642-4060. The assessments are also available in the document library on the EID website.

Testing the Water

To help ensure that safe water is delivered to our customers, EID’s water quality monitoring program includes taking samples of raw and treated water throughout the year from many locations in the District’s service area. Analyses cover more than 100 different constituents. Analysis of the water is performed at state-certified commercial labs. The state of California allows us to monitor for some contaminants less than once a year because the concentrations of the contaminants do not change frequently. Some of our data, although representative, may be more than a year old. When available, the data reported reflects the treated water supply.

A Note For Sensitive Populations

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. USEPA/Centers for Disease Control guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 1-800-426-4791.

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. EID 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 exposure 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 water tested. Information on lead in drinking water, test methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline, or at http://www.epa.gov/safewater/lead.

Your Drinking Water—What You Should Know

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. Environmental Protection Agency and the State Water Resources Control Board prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. State Board regulations also establish limits for contaminants in bottled water that must provide the same protection for public health.

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.
