H KLEINFELDER & ASSOCIATES File: PW86-2016/15 : 405 August 5 , 1986 Page 5 Monitoring Well Development The wells will be developed using a combination of pumping, surging, and air lifting techniques until the water runs relatively clear and free of appreciable fines. Monitoring Well Sampling Each well will be purged by pumping until at least three bore volumes have been removed from the well . Temperature, pH, and conductivity readings will be taken periodically and monitored for stability as an indicator of sufficient purging. Once purging is completed, one sample will be collected from each well . To minimize cross-contamination of samples, all equipment used to obtain samples will be thoroughly steam-cleaned and rinsed with distilled water before the sampling of each well . Samples will be collected by bailing into appropriate containers specified by the analytical laboratory and immediately placed in iced containers. To ensure sample integrity, samples will be handled under strict chain-of-custody procedures. Sample Analyses One water sample from each well will be submitted for analysis. For initial screening we recommend that a total hydrocarbons analysis be run using a Fourier Transform Infrared Spectrophotometry technique, EPA method 418 . 1 . This analysis will provide a quantification of total hydrocarbons present but will not speciate the various hydrocarbon constituents. Should hydrocarbon products be detected in any of the samples, more specific analyses may be required. FINAL REPORT AND RECOMMENDATIONS Upon completion of our field work, a report will be prepared with a description of our field investigation including logs of the soil lithology encountered, results of the laboratory analyses, and recommendations for further investigation, if necessary.
