Background

•
•
•
•
•
EPA lowered the Provisional Health
Advisory Levels (PHA) for 2Perfluorinated Compounds (PFC)
PFC in groundwater is from Site 7;
PFC is in aqueous film forming foam
and used at Site 7.
Well 59 and two private wells
detected PFC above the PHA.
EPA directed water agencies to treat
PHA as a drinking water standard.
Well 59 and two private wells were
shut down.
Air Force assumed responsibility and
prepared an agreement to fund the
cost of water that Well 59 would
have produced.
Requested EMWD to provide water
service to two private well owners.

Environmental Services Cooperative Agreement (ESCA 1)
• Air Force agrees to pay the cost of imported water to
replace the water that Well 59 would have provided.
• Water quantity based the last two years of pumping data.
• Cost of the imported water is based on MWD current and
projected rates.
• Cost developed to provide water service to the two
residents.
• The agreement will retroactively compensate EMWD for
the water purchased since May 20, 2016, for up to three
years or until Well 59 has wellhead treatment.

Next Steps
• ESCA 2 has been drafted and is currently under review;
this second agreement will fund the cost to provide
wellhead treatment for Well 59.
• It is believed that PFC are effectively removed using
Granular Activated Carbon (GAC). There are several
manufacturers of GAC available.
• The AF will fund a cost benefit analysis to compare well
replacement to wellhead treatment.
• ESCA 2 will be presented to the Board for consideration.
• New wells slated to be developed in the area are also
under discussion.

Recommendation
Approve and authorize the General Manger to execute the
Environmental Services Cooperative Agreement Phase 1
with the Air Force Civil Engineer Center for Response
Activities of Off-Base Wells with Perfluorinated Compounds.
