Further investigation is underway because of potential
uses of firefighting foam at OLF Silverhill.
As part of the Preliminary Assessment of OLF Silverhill,
two areas have been identified as potential PFAS release areas.
The findings will be included in a Preliminary Assessment
Report, which should be finalized in 2021.
Due to the identification of potential PFAS release areas,
the Navy is preparing to conduct drinking water well
sampling in a designated area at OLF Silverhill in summer 2021.
The sampling area is shaded purple on the map.
The sampling area was established based on the
location of the potential PFAS release areas on-base and
groundwater flow direction, shown with dark blue arrows on
the map.
The area includes all properties located within a
mile of the OLF boundary in the direction the groundwater flows
away from the potential PFAS release areas.
The Navy is asking to sample drinking water wells only
in these areas.
If your water is provided by Belforest Water, the Navy is
not asking to sample your drinking water.
The Navy may expand the sampling area based on the
results of the summer 2021 sampling of drinking water wells.
