RZAMA Working To Restore Nature February 12, 1993 BP Oil Facility No. 11193, Stockton, California. The water level was allowed to recover to at least 80 percent of the initial water level. A ' sample of the formation water then was collected from the surface of the water in each of the wells with the Teflon bailer and slowly transferred to laboratory-cleaned sample containers. The recovered fluids from sampling in each well were directed into type 17-E, ' steel, 55-gallon liquid waste drums approved for this use by the Department of Transportation. ' Sample Labeling and Handling The soil samples selected for possible laboratory analysis were removed from the sampler and quickly sealed in their brass sleeves with aluminum foil, plastic caps, and aluminized duct tape. The respective sample containers were labeled in the field with the job number, sample location, depth if applicable, and date, and promptly placed in iced storage for transport to the laboratory. Chain of Custody Records were initiated in the field by the • geologist and accompanied the samples to a laboratory certified by the State of California to perform the analyses requested.

The water samples were sealed with •� Teflon-lined lids so that no air bubbles were detected. The sample containers were labeled in the field with the job number, sample location and depth, and date and promptly placed in iced storage for transport to the laboratory. Chain of Custody Records were initiated in ' the field by the geologist and accompanied the samples to a laboratory certified by the State of California for the analyses requested.
