• sample which was submitted to the Canonie Environmental Services Laboratory for analysis The monitoring well was developed by bailing the well with a polyethylene bailer until measurements of the bailed water temperature, pH, and specific c6nductance reached relatively constant values Then a water was taken using a clean polyethylene bailer A volume of water equivalent to six well casing volumes was removed before sampling, The water was emptied from the bailer into sample container which had been obtained directly from the analytical Iaboratory Sample containers were labeled with self adhesive tags, and the project number, sample number, date, and time were recorded on the tag using waterproof ink In addition, the identical information was recorded on the chain-of-custody form Immediately following labelling the samples were placed in a cooler containing blue ice for storage Samples were transported under chain-of-custody procedures to the Canonie Environmental Services Laboratory on the day of their collection A copy of the chain of custody form is included in Appendix E A clean bailer was used to collect the final sample to avoid the possibility of extraneous contamination of the water sample Water samples were transferred from the bailer to the sample container with as little agitation as possible A Volatile Organic Compounds (VOC) sampling port was used to transfer the water to the sampling container in order to minimize the contact with the water to the air The following analyses were performed on the groundwater samples obtained from MW-1 • Total Volatile Hydrocarbons (TPH-gasoline, LUFT Method), e Total Extractable Hydrocarbons (TPH-diesel, LUFT Method,), Y BTEX (EPA 602) This analytical schedule was developed from the RWQCB Tri-Regional Recommendations As a duality assurance/quality control (QA/QC) measure, a trip blank was carried with the sample containers The sample containers and prepared trip blank were obtained from the laboratory The trip blank was analyzed for TPH as gasoline and BTEX with results indicating no detectable volatile hydrocarbons 3.2 Soil Sampling BAI placed additional borings in order to supplement the soil samples taken during installation of the monitoring well and piezometers for the purpose of obtaining additional soil samples at various locations described below 6 BRUNSING ASSOCIATES INC
