Project 113-26, Work Plan Page 4 <br /> All soil cuttings will be stored on-site in 55-gallon Department of Transportation <br /> . (DOT) approved 17 H drums pending laboratory analysis for appropriate disposal <br /> TASK 4 -GROUNDWATER PURGING AND SAMPLING <br /> Monitoring wells will be surveyed by a state licensed surveyor Prior to groundwater <br /> sampling, water level measurement data will be collected from all groundwater <br /> monitoring wells on site The monitoring well will be purged by evacuating a <br /> minimum of three well-casing volumes of groundwater and will be sampled after <br /> allowing the discharge water temperature, specific conductivity, and pH to stabilize <br /> The Parker standard operating procedures for groundwater purging and sampling are <br /> included in the Attachments The monitoring wells will be sampled with pre-cleaned <br /> teflon, stainless steel, or disposable bailers The sample will be sent under chain-of- <br /> custody to a state-certified laboratory. The purged water will be stored on-site in 55- <br /> gallon DOT drums pending laboratory analysis for appropriate disposal. <br /> TASK 5 -LABORATORY ANALYSIS pt L. 2 pr-'VWtp .w 1-" —4- <br /> Soil <br /> ¢Soil and groundwater samples will be sent to a state-certified hazardous materials <br /> testing laboratory, McCampbell Analytical of Pacheco, California All soil samples <br /> selected from the boring and groundwater samples from the monitor well will be <br /> analyzed for TPH-g by modified EPA Method 8015 and BTEX by EPA Method 8020 <br /> TASK 6 -ANALYZE DATA <br /> After the soil and groundwater laboratory data is available, the vertical and lateral <br /> extent of subsurface soil contamination and lateral extent of groundwater <br /> contamination will be evaluated Based on this data, a remediation work plan can be <br /> developed, if necessary <br /> TASK 7-PREPARE REPORT <br /> Following completion of the field work and receipt of analytical data, a summary <br /> report documenting the field work, presenting analytical data and outlining the <br /> findings and conclusions will be submitted to the appropriate agencies <br /> Parker Environmental Services, 4185 Rialto Court, Pittsburg, CA 94565-6116 <br /> Phone (510) 439-1024 Fax (510) 439-2566 <br />
