I Sam ling Procedure anJI AnalLysis Schedule ' A sampling order was established prior to this sampling round, based on analytical results from the last quarter samples The wells were sampled in the following order• ' I MW-4 2 MW-6 3 MW-3 ' 4 MW-5 5 MW-1 6 Mw-2 ' To sample each well, a pre-cleaned teflon bailer was attached to new braided nylon line and lowered into the well, filled, and brought to the surface. The water in the bailer was carefully poured into laboratory prepared glass bottles which were capped with Teflon-lined caps Sample bottles were labeled with stick-on labels filled out in indelible ink, with the following information Site name Date coIIected Time collected Sample ID Sampler's initials Analysis required Any other pertinent information Quality control/quality assurance procedures consisted of the collection of a blind duplicate and an equipment decontamination nnsate sample The duplicate was collected concurrently with ' sample MW-1 and was given the fictitious well/sample name MW-13 The decontamination sample (labeled MW-I2) was collected from a bailer which had been cleaned by the normal decontamination procedure after sampling MW-1 Deionized water was poured into the decontaminated bailer and then the water was poured from the bailer into the sample bottles This sample serves as a check on the decontamination procedures for the bailer, ensuring that it has been effectively cleaned ' The teflon bailer used to purge the wells and collect the water samples was thoroughly decontaminated prior to each use to prevent cross-contamination of samples Decontamination of the bailer consisted of a dual wash with an alconox/potable water solution followed by a ' potable water rinse, and a final rinse with distilled water The thin nylon line used to lower the bailer was removed and discarded after each use ' All purge water from the wells and decontamination nnsate was transferred to a 700-gallon poly- tank located onsite At the end of the sampling round, the tank contained approximately 680 gallons of water A sample from the tank, coded Tank-61$93, was collected at the end of the ' sampling round to characterize the contents for disposal Based on the analytical results, the contents of the tank will be disposed in an appropriate manner prior to the next sampling event MX%RPrS\AREG2QTR WP A - 3 08105/93
