<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 (BTEX), volatile organic compounds
<br /> (VOC), inorganic ions (bromate, bromide, chloride, nitrate, nitrate as nitrogen, nitrate as
<br /> NO3_, sulfate), aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium III,
