<br />The San Joaquin County Environmental Health Department (EHD) has reviewed Corrective
<br />Action Plan (CAP), dated 11 March 2014 and Semi-Annual Groundwater Monitor Report,
<br />Fourth Quarter 2013 dated 04 February 2014 prepared and submitted by your consulting firm,
<br />Advanced GeoEnvironmental, Inc. (AGE), on your behalf for the above-referenced site.
<br />In the CAP, AGE proposes a scope of work that includes:
<br />Installation and development of nine-shallow screened (10-25 feet bsg) and seven-
<br />intermediate screened (30-50 feet bsg) injection wells;
<br />Monthly Injections of diluted solution of hydrogen peroxide into the proposed wells and
<br />selected existing wells;
<br />Submittal of applicable boring or well installation permits to the EHD and an updated
<br />health and safety plan, with clearly marked proposed boring/well locations and obtaining
<br />a utility clearance;
<br />Reporting the findings from the remedial well installations and submitting quarterly
<br />reports from monthly injection events; revised monitoring and reporting program (MRP)
<br />will be prepared and submitted to CVRWQCB;
<br />Collection of soil samples at 5 feet intervals beginning at 5 feet bsg using a California
<br />modified split-spoon sampler fitted with 2-inch diameter, 6-inch long steel sleeves for soil
<br />for classification and field screen the samples for presence of volatile organic
<br />compounds (VOC) using an organic vapor meter (OVM) with a photo-ionization detector
<br />(PID);
<br />Reporting of field parameters including depth to water in shallow and intermediate
<br />groundwater monitoring wells MW-1A/B, DPE-1, DPE-2, MW-2, MW-3, MW-4, MW-9,
<br />MW-15, MW-17 and MW-19; reporting of temperature, pH, TDS, oxygen reduction
<br />potential (ORP), salinity, turbidity, and dissolved oxygen (DO).
<br />Analysis of groundwater samples for total petroleum hydrocarbons as gasoline (TPH-g);
<br />benzene, toluene, ethylbenzene and total xylenes (UFA), volatile organic compounds
<br />(VOC), inorganic ions (brornate, bromide, chloride, nitrate, nitrate as nitrogen, nitrate as
<br />NO3", sulfate), aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium Ill,
