Water Resources

To help protect the quality of existing and future groundwater supplies, the Drinking Water Source Assessment and Protection (DWSAP) program calls for examining the vulnerability of drinking water sources to potential contamination. The Water Agency completed this comprehensive report in January 2008.

Notes

1. The state allows SCWA to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. The 2014 Water Quality Data is based on data years 2005 thru 2014.
2. The State of California has set 10 PPB as the MCL for chromium-6, beginning July 1, 2014. Chromium-6 is one of the forms of chromium making up total chromium which has a California MCL of 50 PPB.
3. For more information about Chromium-6, please visit the StateWater Resources Control Board's website: www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/Chromium6.shtml
4. Total Trihalomethanes = sum of results for Chloroform, Bromoform, Dibromochloromethane, & Bromodichloromethane.
5. Haloacetic Acids = sum of results for Bromochloroacetic acid, Dibromoacetic acid, Dichloroacetic acid, Monochloroacetic acid, & Trichloroacetic acid.
6. The Mather-Sunrise water system’s facilities are all fluoridated and the system is currently at optimal levels. The Optimal Fluoride Level and Control Range for the system is based on an annual average of maximum daily air temperatures in the Mather-Sunrise area. In accordance with Title 22, Section 64433.2 of the State Water Resources Control Board (State Board) regulations, the Optimal Fluoride Level is 0.8 mg/L and the Fluoride Control Range is from 0.7 mg/L - 1.3 mg/L. Information about fluoridation, oral health, and current issues is available from www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/Fluoridation.shtml.
7. On Systems that collect less than 40 samples per month, the Total Coliform Bacteria MCL is one (1) Total Coliform positive sample, per the Total Coliform Rule (TCR). A positive TC sample triggers collection of samples for E. coli at the source (i.e., groundwater wells) per the federal Ground Water Rule (GWR). In 2014, all samples taken per the GWR returned negative (absent) for E. coli.
8. SCWA Level for Lead & Copper is measured from the 90th percentile of 31 tap water samples. The MCLs for lead and copper are set at "Action Levels."
9. Unregulated Contaminants Monitoring Rule (UCMR 3 / 2013 - 2015 Monitoring) with notification Levels help to determine where certain contaminants occur and whether they need to be regulated.

SCWA received an insignificant amount of water (0.01%) for the Mather / Sunrise & Anatolia system from the Golden State Water Company.

State Mandated Information for Nitrate, Arsenic & Lead

The State Water Resources Control Board (State Board) requires the following language about arsenic and lead to be used by water agencies that have traceable amounts of these substances in their water systems. These do not apply to the Water Agency’s water systems; where found, the amounts do not exceed acceptable federal and state standards. Additional information is provided about hardness to help answer customers’ frequently asked questions. It is important to realize that the majority of water quality issues apply to both tap and bottled water.

Lead

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. The Sacramento County Water Agency 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 you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline (1-800-426-4791) or at http://www.epa.gov/safewater/lead.
