From: Mark Finucane, Subject: Contract 29-322
Health Services Director AB 1803 Program
Under Contract 29-322 with the State of California, Department of Health Ser-
vices, the Health Services Department has been assessing small water systems in
the County to determine the extent of organic chemical contaminants in these
systems. This one time only contract for $56,925 which was approved by your
Board on February 11, 1986 was funded under AB 1803. On June 17, 1986 the
contract was amended to increase the State funding by $5,670 to a new payment
limit of $62,595.
All testing of the water systems was completed by November 1986 and we have pre-
pared a final ,;,report to the State documenting the activities and findings of
our local AB 180:1 program.
In summary, that report indicates the following:
1. Seventy-seven (77) County water systems, served by wells,
were evaluated. The systems are located in south county,
west Pittsburg, Antioch and east county.
2. The type of laboratory analyses was determined by examining
the historical presence of organic compounds in the general
area of a particular water system. The types of analyses
included heavy agricultural , medium/light agricultural, range
land or similar land uses, industr.ial and residential/commer-
cial .
3. Of the water systems evaluated, four contained detectable
amounts of organics. None of these contained significant
levels compared .to health action levels set by the State.
However, these owners have been notified that an annual
retest will be necessary to ensure that the level of organics
remains safe.
In conclusion, we are pleased to report that Contra Costa County' s small water
systems do not exhibit levels of organic contaminants that pose any threat to
the health of the consumers.
