Revisions to the QAPP focus mainly on naming additional <br /> chemical and geotechnical laboratories in the project plan and appending their respective statements of <br /> qualifications. Revisions to the FSP focus on adding or modifying procedures for cone penetration <br /> testing of discrete groundwater and soil samples, hollow stem auger direct push soil sampling and BAT <br /> system groundwater sampling,multi-completion wells construction, and the LNAPL and DNAPL <br /> measurements. In the revised LNAPL and DNAPL measurement procedure, electronic interface probe <br /> measurements will now be taken quarterly in wells what have historically contained concentrations <br /> greater than 1,000 µg/1 of total hazardous substances. These revisions to the QAPP and FSP are <br /> approved. <br /> KIT CUSTIS <br /> Associate Engineering Geologist <br /> cc: San Joaquin County Environmental Health, Stockton <br /> Mr. A.J.
