Hi Caleb-
Thanks for returning my call this morning. In follow-up, specifics for the field test are provided
below.
The South Tahoe Public Utility District is planning to conduct a field test in support of an engineering
Feasibility Study to identify the most cost-effective means of mitigating a chlorinated hydrocarbon
contaminant plume. The field test would involve the performance of a short-term groundwater
pumping test at a site in South Lake Tahoe, California. For planning purposes, the pumping test
would be performed at a maximum flowrate of about 200 gallons per minute (GPM), with an
expected contaminant influent concentration of about 50 µg/L [tetrachloroethylene (PCE)].
Discharge to the sanitary sewer will require removal of PCE from the extracted groundwater to
below drinking water standards (5 µg/L). The total duration of the pumping test is estimated at
about 100 hours.
Can you please provide a cost estimate along with engineering details for the equipment Pure Effect
could provide for this field test.
Nice talking with you and again thanks for your reply,
