SUBJECT: Toxics in Water Wells , GBF/Antioch Landfill Site
Supervisor Torlakson commented that at his request Dr.
Wendell Brunner and Mr. Dan Bergman from the County Health Department
were present to report on the recommended approach to the report of
the Central Valley Regional Water Quality Control Board indicating
that tests performed at the GBF Antioch Landfill Site have shown
that there is migration of various toxics in the groundwater, in the
acquifer underlying that site.
Supervisor Torlakson further commented that he was con-
cerned that the Central Valley Regional Water Quality Control Board
had not reported to this Board of Supervisors nor to the County
Health Department with respect to its concerns, testing procedures
and whether the wells in the area were being used for domestic
water. He suggested that perhaps the Regional Water Quality Control
Board be invited to appear to brief the Board with respect to the
problems at the GBF site.
Dr. Wendell Brunner advised that the Water Quality Control
Board had required that monitoring wells be placed around the GBF
site and that these wells were deep enough to reach an acquifer pre-
viously not reached and in the samples they identified a variety of
organic, toxic constituents. He advised that in going through the
Department' s permitting records , they have not been able to identify
any permitted well within one and one half to two miles of the site,
but stated that the Health Department would like to be informed if
there are any wells closer to the site. He stated that his
Department had been in contact with the Regional Water Quality
Control Board and they understand that it' s probably appropriate to
move to identify the extent of groundwater contamination in that
area and would be moving in that direction.
Dan Bergman commented briefly that there are four sites,
all adjacent to each other and that one site is still active and
receiving Class II materials, not hazardous waste. The other sites
were closed in 1974 and filled over a period of four years under the
auspices of the State Health and Regional Board and then clay
capped. He stated that apparently the caps, while preventing off-
gassing have not prevented the migration of toxics in the lechate
and there is a need for identification.
Board members discussed the situation and possible actions
that might be taken, including developing better communication with
the Central Valley Regional Water Quality Control Board.
As recommended by Supervisor Torlakson, the Board hereby
takes the following actions:
1. Expresses its serious concerns regarding lack of com-
munication by the Central Valley Regional Water Quality Control
staff with Contra Costa County, particularly with the County' s
Health Department staff. Directs that a letter be sent to the
Regional Water Quality Control Board and to the State Department of
Health expressing this Board' s concerns.
1
2 . Requests the County Health Department to contact the
Regional Water Quality Control Board. and obtain information for a
report to the Board of Supervisors regarding:
A. Further testing as soon as, Ipossible to determine
the extent of containment migration .in the ;acquifer.
B. Determination of an action plan to stop the
contamination. The Health :Department . staff should prepare this
report soon and make a presentation toa' the Board. The Regional
Water Quality Control Board staff should' be invited to attend when
this matter is presented to the Board of Supervisors.
3 . The County Health; Department and Public Health Officer
are directed to further review use of wells in the area and let the
public know that the County will provide testing services for any
wells in the vicinity which the County is not aware of at this time.
I hereby certify thst:his is a true and correct copy of
an action taken and antered on the minutes of the
Board of Supervisors on the date shown.
