I . RECOMMENDED ACTION : Accept report from the Health Services
Department regarding Drinking Water Wells in the Vicinity
of the IT Corporation Facility, Vine Hill .
II . FINANCIAL IMPACT: None.
III . REASONS FOR RECOMMENDATION/BACKGROUND : On Tuesday, June 9,
1987 , a report was made to the Board of Supervisors
regarding groundwater wells in the vicinity of IT
Corporation ' s Martinez sites ( see Determination Item 2. 8,
6/9/87 Board Agenda ) . A summary of that report follows .
A review of Contra Costa County Environmental Health
records reveals no domestic wells within 12-2 miles of the
IT facilities . The Department of Water Resources and the
San Francisco Regional Water Quality Control Board also
have no record of domestic wells near Baker or Vine Hill .
Tosco has a number of monitoring wells and recovery wells ,
in addition to a small water system supplied by ground-
water. These wells are approximately 2 mile northeast of
IT. The monitoring wells are sampled for total petroleum
hydrocarbons , benzene, toluene, xylene, arsenic , chromium
and lead . None of these pollutants have been detected ,
according to Tosco ' s consultant .
Monsanto also has monitoring wells . These are located 2
mile east of the Baker ponds .
The Contra Costa Water District has backup water supply
wells near Mallard reservoir. They are 12-2 miles east of
the IT facilities . Contaminants have not been detected in
these wells . They were installed during the drought but
have never been used .
A request was made through the press for any property owner
near IT with a domestic well (unregistered with the county
or DWR ) to notify the Environmental Health Division . If
any such wells are reported , our intent is to sample them.
