M references, i. e. the report, chain-of-custody, lab results, site plan. Samples will be placed into an ice chest containing blue ice and having a constant temperature of 4 degrees Celsius/39.2 degrees Fahrenheit and monitored with a # thermometer to ensure that the temperature remains constant for delivery to the E laboratory for analysis. Equipment will be decontaminated between sampling. The € sample tubes, split spoon sampler, and all other sampling equipment will be pre- cleaned. This equipment will be washed with non-phosphate detergent and twice rinsed with distilled water. Cleaned sample tubes will be stored in clean plastic bags. Chain-of-custody protocol, described in USEPA 1986, Test Methods for Evaluating Solid Waste, SW-846, 3rd ed. will be followed. These records will include: ample location, depth, date time, job number, temperature of sample i container, field identification number, analysis required, and personnel ! collecting samples. A field log book will be maintained containing, essentially . the same information as the chain-of-custody record with the addition of any field observation about the sample. The temperature within the ice chest will ' be monitored and recorded during the course of the transport and delivery to a State certified hazardous waste testing laboratory within 24 hours after the M sample is collected. The temperature will be maintained below 4 degrees Celsius ! *. in the insulated storage container prior to delivery to the laboratory. Upon arrival at the laboratory, the samples will be preserved for analysis in accordance with regulatory requirements. Subsurface conditions, sampling intervals and other pertinent observations will be recorded on a detailed log for each soil sample. Chain-of-custody will be signed by the laboratory indicating that possession of samples has changed. The temperature of the storage r container will be recorded on the Chain-of-Custody form upon delivery at the I laboratory. The soil samples will be analyzed within the required 14-day period following collection, unless a 24 or 48 hour rush is requested. k Personnel involved in collecting the soil samples and classifying the soils will be under the direct supervision of the project engineer and fully experienced i in the field of environmental and geotechnical drilling. Additional samples will be obtained from borings/wells on the plume edge, PED field screened and actionable samples sent to the laboratory for analysis during the bioremediation drilling process, the interim monitoring phase, and final closure phase and handled in a similar manner. This will confirm the plume boundary. Soil cuttings from sampling will be properly contained on impermeable ~ membranes, diked and covered according to PHS-EHD and CWQCB guidelines, and ex situ remediated. These cuttings will be contained on site until verification of site clean up levels per FHS-EHD and CWQCB standards. This sampling protocol will i be divided into two (2) distinct areas: No. 1, Soil Sampling Protocol ; and No. 2, Water Sampling Protocol. a. Soil Sampling Protocol The soil samples selected for chemical analysis via field screening, will be done with a PID and will be retained in brass or stainless steel liners with zero i headspace, sealed with Teflon tape and plastic caps, put into sealable plastic bags, and placed in an ice chest containing crushed ice for delivery to a state- certified, independent laboratory. Labels will be placed on the samples identifying the project number, date, sampler' s initials, boring number, and sampling depth. In addition, each soil sample will be recorded on a Chain-of- Custody form identifying the soil sample, sampler' s initials, date appropriate l analytical tests, couriers used, and responsible laboratory personnel. n f. 103
