Martin Thorpe _ - WEISSM "'OKin '`, - <br /> 19 May 1987 2 <br /> a <br /> Task 1) Drill three borings, collect soil samples at 5-ft intervals, <br /> analyze one sample per boring and install three 4-in, diameter <br /> ground water monitoring wells in the boreholes. <br /> Task 2) Develop the three wells, collect and analyze samples of ground <br /> water and development water. <br /> Task 3) Prepare a report that includes: F , ;i,_ a <br /> - Site background and description of work.performed, y <br /> T 3 <br /> - Boring logs and well construction details; <br /> - Laboratory analysis reports; <br /> - Data analysis, interpretations and conclusions. <br /> Each of these tasks is described bele` and a tailed cost estimate is <br /> presented in the attached budget. <br /> TASK 1 - SOIL SAMPLING AND MONITORING WELL INSTALLMON_ <br /> Three borings will be drilled to an anticipated depth of 40 to 45 ft. 'A <br /> WA field geologist will log the borings and collect soil samples every -5 ft W. <br /> document lithology and for possible chemical analysii. All soil samples will <br /> be submitted to an analytic laboratory and one saturated soil sample per <br /> boring will be analyzed by gas chromatography/flame ionization detection <br /> (GC/FID) for TFNC and benzene, toluene and xylene (BTX) ; by EPA Method 8010 <br /> for ethylene dibromide (EDB) and other halocarbons ; and by Atomic Absorption <br /> (AA) for soluble lead (SL) . A portable organic vapor analyzer (OVA) will be <br /> used to detect the presence or absence of hydrocarbons in the soil samples and <br /> help determine which soil samples will be analyzed. If the OVA detects <br /> hydrocarbons in unsaturated soil, the SJLND may require analysis of soil <br /> samples from the interval where the positive readings were noted. If this is <br /> necessary, WA will provide an estimate for the additional analysis. <br />
