SPntember 5.2001 prior to drilling each boring. The lithology and other pertinent data will be recorded on a field boring log in accordance with Method D 2488-84 for visual description and identification of soils. Soil cuttings generated during drilling operations will be drummed pending proper disposal and the boreholes will be backfilled with a neat-cement grout with approximately 5% bentonite powder added. Note: The boreholes that encounter groundwater will be filled to 5 feet above the water table with bentonite pellets. The pellets will be allowed to hydrate for a minimum of one (1) hour prior to slurrying the remaining borehole. 4.3 Soil Sampling Soil samples will be collected using a California split-spoon sampler containing three 2-inch x 6- inch brass or stainless steel sleeves that is driven by a 30-inch fall of a 140-pound hammer, or pneumatically simulated, at each sampling point. Soil samples will be driven at 5-foot intervals to total depth in each boring. Sample lithology, pertinent drilling and hydrocarbon monitoring information will be described and recorded on field boring logs by an experienced environmental geologist working under the supervision of a California Registered Geologist. One sleeve with soil from each interval will be capped, sealed, labeled in accordance with EPA protocols, recorded on a Chain-of-Custody form, and then placed in an iced cooler at 40 centigrade. The samples in the iced cooler will be transported to a State of California-Certified analytical laboratory with the Chain-of-Custody for the specified analyses. All sampling equipment will be cleaned in an Alconox solution and double rinsed prior to each use. 4.3.1 Field Screening of Soil Samples Soil samples will be collected as discussed above. Generally, the middle sample tube will be immediately sealed, labeled and stored in an iced cooler after collection and retained for possible chemical analysis. The bottom tube will be used for lithologic description, and hydrocarbon field screening. Field screening for the presence of volatile organics will be conducted by sealing the brass liner with plastic end caps and allowing the sealed liner to standard period of time after which a headspace reading will be measured through a slit cut into the plastic cap on one end and noted on the boring log. Field screening will be accomplished using a Foxboro hydrogen flame-ionizing detector (FID). 4.3.2 Soil Chemical Analyses Based on the Site history, it is estimated that twenty (20) representative samples from the soil borings (four per boring) and four (4) from the hand-auger boring (total of 24 soil samples) will be submitted for halogenated volatile organic compound (HVOC) analysis. These samples will be analyzed at Halcyon Laboratories, a State of California-Certified Analytical Laboratory (Certification#1920) in accordance with State guidelines and EPA protocol using EPA Method 8260b. Note: The compounds will be reported as an 8010/601 list using a GC/MS method. 4.4 Collection of Grab Groundwater Samples After groundwater is encountered, the auger will be lifted slightly thus allowing water to enter the auger. A disposable bailer will be lowered into the auger and a sample will be retrieved. The sample will be decanted into two (2) 40-milliliter (ml) volatile organic analysis (VOA) containers. These containers will be filled such that no headspace exists. Sample containers will 4 E,C Remediation, LLC
