The California Department of Health
Services (DHS) requires water providers to conduct a source
water assessment to help protect the quality of future water
supplies. This assessment describes where a water system's
drinking water comes from, the types of polluting activities
that may threaten source water quality and an evaluation of
the water's vulnerability to those threats.
To meet the DHS requirements and provide our customers with
information about our customers with information about our
water supply, the district completed its surface water assessment
in May 2003 and its groundwater assessment in July 2003.
The results indicate that our surface water source (the American
River) is considered most vulnerable to contamination from
sewer system spills, body contact recreation, urban runoff
and discharge of regulated and unregulated contaminants. The
contaminants to which the surface water sources are considered
most vulnerable include the following:
| Percholorate, nitrosomodimethylamine
and volatile organic, chemicals discharged into the American
River by the Aerojet General Corporation. Aerojet is under
the joint regulatory oversight of the EPA, California
Department of Toxic Substance Control and the California
Regional Water Quality Control Board. |
The groundwater sources are considered
most vulnerable to the following activities associated with
contaminants detected in the water supply: dry cleaners and
manufacturers of rocket fuel. In addition, the groundwater sources
are considered most vulnerable to these activities:
| Illegal activities and
unauthorized dumping |
| Sewer collection systems
|
| Dry cleaners |
| Automobile repair shops
|
| Chemical/petroleum pipelines
|
| Electrical/electronic
manufacturing |
| Underground storage
tanks |
| Gas stations |
A copy of complete assessment is available for inspection at
the Carmichael Water District offices.
