Re: [CPEO-MEF] Irvine Desalter/TCE remediation project

In reviewing a specific project at Moffett Field, I noted that EPA's
definition of "potential drinking water" includes groundwater with a
Total Dissolved Solids (TDS) concentration of 10,000 mg/L or less, and
an average yield of 150 gallons per day (gpd), as compared with the
California State Water Board's definition of TDS at 3,000 mg/L or less
and an average yield of 200 gpd. That means that in terms of defining
potential drinking water, the federal government is more stringent than
California, and covers a wider swath of groundwater.  EPA's definition
trumps California's until the state has an EPA-endorsed Comprehensive
State Groundwater Protection Program.
