collection using a 2-inch-diameter, electric, submersible pump. Field measurements of pH, SC, and water temperature were taken at frequent intervals during purging process. Once the well had been purged a minimum of three well volumes, and the temperature, pH, SC of the purge water had stabilized, the wells were sampled using a disposable bailer. Due to the limited I saturated thickness in Wells BC-2 through BC-5, it was only possible to remove approximately one well volume before these wells were bailed dry. Review of the field data sheets indicated that Well BC-6 was not sampled during the February, 1997 monitoring event. Therefore, on March 7, 1997, Brown and Caldwell revisited the site, collected depth-to-water measurements from the 10 on-site wells, and collected a groundwater sample from Well BC-6. Sample collection procedures followed those discussed above. Samples collected from each well were transferred from the disposable bailer into two 40-milliliter glass vials and labeled to identify the sample location, the date and time of collection, the sampler, the type of analysis requested, and the project number. The containers were sealed, a visual check was made to confirm no head space or air bubbles remained in the containers, and then placed in a cooler containing crushed ice. The samples remained in the cooler, in the possession of the Brown and Caldwell field technician, until delivery to VOC ` Analytical Laboratories, Inc. for analysis. Non-dedicated downhole equipment was cleaned before use, and between each use, by rinsing first with bottled water containing a non-phosphate detergent followed by a double rinse with clean bottled water. The submersible pump used to purge most of the wells was cleaned prior to use, and in between each well, by thoroughly washing the exterior of the pump with bottled water containing a non-phosphate detergent, then purging through the pump approximately 10 gallons of the same, followed by 10 gallons of clean bottled water. Development and purge water generated during this investigation was placed in 55-gallon drums. A sample was collected from the stored water for waste characterization prior to disposal.
