REPORT PREPARATION <br /> Upon completion of field work and receipt of final laboratory analysis, a report will be prepared <br /> presenting the findings of the investigation. The report will include a description of the work <br /> performed and results of the sampling and analysis.Conclusions,recommendations,maps and cross- <br /> sections will be included in the report. The report will be in a format acceptable to the PHS-EHD <br /> and the CVRWQCB, and will be reviewed and signed by a California Registered Geologist. <br /> 4.4. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist.Procedures for the excavation of soil,advancement of borings, soil sampling, <br /> ground water sampling, equipment decontamination and sample shipment are given below. <br /> 4.1. EXCAVATION <br /> A backhoe will be used to excavate soil in the suspected shallow-disposal well area to a depth of <br /> approximately 5 feet below surface grade.Excavated soil will be visually inspected for discoloration <br /> and screened for the presence of volatile organic compounds using an organic vapor meter(OVM), <br /> equipped with photo-ionization detector(PID). <br /> If indications of contaminated soil or the presence of a shallow disposal well (e.g. the presence of <br /> drain rock)are noted,then additional soil may be excavated at the discretion of AGE.The excavated <br /> soil will be stockpiled on-site pending sampling and characterization. <br /> If appropriate, soil samples will be collected from the floor of the excavation. Samples will be <br /> collected from the backhoe bucket using a metric soil sampler and brass sleeves. Upon collection, <br /> the ends of the lead brass sleeve will be covered with Teflon sheets, capped and sealed with tape. <br /> Appropriately sealed and labeled samples will be placed in a chilled container under ice and <br /> transported under chain-of-custody to a DHS-certified laboratory.Each sample sleeve will be labeled <br /> with the boring designation, depth, time, date and sampler's initials. The samples will be analyzed <br /> as described in Section 3.3. <br /> 4.2. PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using a van-mounted Geoprobe 5400 direct-push probing unit <br /> Advanced GeoEnvironmental,Inc. <br />
