EA <br /> 1M. <br /> "ml _ <br /> va <br /> or three feet into the first competent clay layer, Total <br /> - anticipated depth of the wells will be a maximum of go feet. The �1 <br /> wells will be constructed according to the protocol in Appendix B. <br /> " A well-construction diagram (Figure 3) is included at the back of <br /> Appendix B. <br /> After the well; have been constructed, and a minimum of <br /> 48 hours has elapsed since their development, the following <br /> steps will be performed for each well: <br /> l'3 <br /> An initial depth to water measurement will be taken, and <br /> the well will be purged by removing three well volumes of <br /> water by nitrogen pumping and/or bailing; after the well has been <br /> i - allowed to recover to 90 percent of its initial level, groundwater <br /> ; . samples will be collected in a Teflon bailer, poured into <br /> c . <br /> ° laboratory cleaned glass VOAs and 1-liter amberglass bottles, <br /> labeled, at-.d refrigerated for transportation to the laboratory. <br /> Well development water will be drummed and stored on site for <br /> !` V later treatment or disposal. The treatment or disposal of the <br /> water is beyond the scope of this Workplan but will remain the <br /> responsibility of the client, unless other arrangements have been <br /> made in advance. <br /> 1 k <br /> Soil cuttings from the drilling operation will be placed in <br /> 55-gallon drums and stored on site for later disposal or <br /> treatment. <br /> A factual report will be generated at the conclusion of <br /> this phase of the investigation. THQ report will contain all <br /> ! � laborator,, data, groundwater gradient information, and other <br /> to pertinent information collected during the investigation. <br /> ETS ENVIRONMENTAL 6 ASSOC. <br /> f ; <br /> PROJECT N0. 305, PAGE 5 <br />
