Workplan for Monitoring Well Installation <br /> Flag City New West#1003,6437 West Banner Street,Lodi,California <br /> Page 4 <br /> SOIL SAMPLING <br /> Monitoring well soil samples will be collected at 5-foot intervals bgs and at obvious lithologic <br /> changes. A minimum of three soil samples from each boring for each well will be submitted to a <br /> State-certified laboratory under chain-of-custody(COC) documentation for analysis. Soil <br /> lithology and visual and olfactory observations will be recorded in the field and used for the <br /> possibility of additional soil sample submittal. In addition, all soil samples will be field screened <br /> with the use of a photo,ionization detector(PID). All fieldwork will be conducted in accordance <br /> with the Apex SOP (Appendix B). Soils encountered during the well installations will be logged <br /> according to the unified soil classification system, under the supervision of a State of California <br /> registered professional geologist. SJCEHD will be contacted at least two days prior to initiating <br /> field activities. <br /> All soil generated during drilling activities will be temporarily stored in a roll-off bin pending <br /> receipt of laboratory analytical results. Once the analytical results are reviewed, a proper <br /> disposal method will be determined. <br /> GROUNDWATER SAMPLING <br /> The new groundwater monitoring wells will be developed,water levels recorded, and sampled, <br /> according to the Apex SOP, and the top of the casing elevations will be surveyed, referenced to <br /> mean sea level by GeoTracker standards.. <br /> All groundwater samples will be submitted, under COC documentation, to a state-certified <br /> laboratory. <br /> ANALYTICAL PROCEDURES <br /> All soil and groundwater samples will be submitted for analysis of: <br /> Analysis Abbreviation Designation USEPA Method No. <br /> Total Petroleum Hydrocarbons TPHg Gas Range 8015M <br /> as Gasoline Hydrocarbon <br /> Benzene Aromatic <br /> Toluene BTEX Volatile <br /> Eth (benzene Organics <br /> Xylenes Total <br /> Tertiary Butyl Alcohol TBA 82608 <br /> Methyl Tertiary Butyl Ether MTBE <br /> Di-isopropyl Ether DIPE Seven Fuel <br /> Ethyl Tertiary Butyl Ether ETBE Oxygenates <br /> Tertiary Amyl Methyl Ether TAME <br /> Ethanol 8015M <br /> Methanol <br />
