r if <br /> kP <br /> A' <br /> Disadvantages associated with{Middleburg pumps include their high cost, low flow rate, <br />! temperamental operation, and cleaning requirements which are both elaborate and time i <br /> consuming: i <br /> i - <br /> Decontamination <br /> All apparatus is brought to the'site in clean and serviceable condition. The equipment is <br /> decontaminated after each uselrand before leaving the site. ! <br /> Effluent Materials <br /> The evacuation process creates a volume of effluent water which must be contained. Blaine <br /> Tech Services, Inc. will place this water in appropriate containers of the client's choice or bring <br /> ,r ' <br /> drums to the site which are <br /> new 55 gallon DDT X7 E ruappropriate for the containment of the <br /> effluent materials. The determination of how to properly dispose of the effluent water must <br /> usually await the results of laboratory analyses of the sample collected from the groundwater i <br /> well. If that sample does not establish whether or not the effluent water is contaminated, or if <br /> effluent from more than one source has been combined in the same container, it may be <br /> necessary to conduct additional analyses on the effluent material. <br /> Sampling Methodology <br /> i Samples were obtained by standardized sampling procedures that follow an evacuation and <br /> sample collection protocol. The sampling methodology conforms to both State and Regional <br /> Water Quality Control Board standards and specifically adheres to EPA requirements for <br /> I apparatus, sample containers and sample handling as specified in publication SW.846 and <br /> T.E.G.D, which is published separately. <br /> Sample Containers I� <br /> I <br /> Sample containers are supplied by the laboratory performing the analyses. <br /> a . <br /> Sample Handling Procedures <br /> Following:collection, samples are promptly placed in an ice chest containing deionized ice or an , <br /> inert ice substitute such as Blue Ice or Super Ice. The samples are maintained in either an ice <br /> chest or a refrigerator until delivered into the custody of the laboratory. <br /> I I <br /> i <br /> , <br /> Blaine Tech Services,Inc.Report No.950802-S-2 Pacific Environmental Group,Inc.
