Greetings to the SSFL Community:
This year, our major goals at the U.S. Department of Energy (DOE) Energy Technology Engineering Center (ETEC) are
to complete investigations and analyses of groundwater and publish the draft Environmental Impact Statement (EIS) which
will evaluate clean-up options for the remediation of Santa Susana Field Laboratory (SSFL) Area IV. With that in mind,
we are devoting this issue of the CleanUpdate to the progress we’ve made addressing groundwater contamination issues
since release of the 2009 Groundwater Remedial Investigation Report. Scientists have concluded TCE (trichloroethylene) is
the primary contaminant of concern in Area IV groundwater, with smaller amounts of perchlorate, strontium-90 (Sr-90),
and metals, plus a tritium plume.
