i Kennedy/Jenks/Chilton i DRUM CONTENTS SAMPLING ' On 10 May 1990 and 11 May 1990, fluid samples were collected from the drums. Field activities were performed by Peregren and Kennedy/Jenks/ Chilton. All sampling personnel were health and safety trained in ' compliance with 29 CFR 1910 120 Fluid samples were collected using a Composite Liquid Waste Sampler (COLIWASA) which is an EPA recommended sampler for drums containing liquids. The COLIWASA allows for the 1 collection of a sample which is representative of potential vertical stratification of liquid waste contained within a drum Fluid collected from an individual drum was placed in two 100-milliliter amber glass ' vials with tight fitting caps. During sampling, a small amount of the fluid from each drum was placed into clear disposal containers for visual purposes. On the basis of a visual inspection, the drum contents were grouped according to visual characteristics. A total of nine groups were identified Composite fluid samples were then collected from each group. A total of nine groups were identified. Composite fluid samples were then collected from each group. The composite drum ' samples (CS-1 through CS-9) were collected in one-liter glass bottles for laboratory analyses. Composite fluid sample 55A/55B was collected from the one-gallon glass container in two 100-milliter amber glass vials for laboratory analyses. A strong pesticide-like odor was noted t while sampling the fluid contained within the glass bottle that was found in the warehouse Table 7 provides the schedule used for compositing drum samples After sample collection, the glass sampling containers were secured with tight fitting caps. A completed label was attached to each container 1 with the following information site name, collection date/time, sample number, sample depth, and collector's initials. Samples were temporari- ly stored and transported in a chilled ice-chest under Chain-of-Custody to the Kennedy/Jenks/Chilton Laboratory Division in San Francisco, California. LABORATORY ANALYSES RESULTS ' Drums Composite fluid samples CS-1 through CS-9, collected from the drums, ' were analyzed for organochlorine pesticides by EPA 8080 and for Total Petroleum Hydrocarbons by modified EPA Method 8015 Organochlorine pesticides were not detected above method detection limits in these ' samples However, the detection limits were elevated due to sample dilution required by the laboratory sample preparation procedures TPH were detected at concentrations ranging from 1) 0.40 mg/L to 6 7 mg/L as gasoline, 2) 23 mg/L to 650 mg/L as diesel fuel , and 3) 190 mg/L to 3,500 mg/L as motor oil . Table 8 provides the concentrations of TPH detected in the nine fluid samples collected A copy of the laboratory reports is included in Appendix A, Part 5. WPI13 5 2 882526.01 i
