Ripona Market <br /> Subsurface Sod & Groundwater Investigation <br /> samples will be collected at various depths and will include soil from the backfill material <br /> and the groundwater interface Since groundwater has been identified in the area at 35 <br /> feet in depth, a water sample will be obtained prior to termination of the boring Samples <br /> will be analyzed by GeoAnalytical Laboratories for gasoline BTEX, & MTBE The soil <br /> sample with the highest concentration of MTBE and the water sample will be analyzed <br /> for the Oxygenated Compounds using Method 8260 <br /> A report of the subsurface investigation containing site map, boring logs, and soil and <br /> groundwater sampling records with laboratory data sheets will be prepared at the end of <br /> this phase of work All work will be certified as conducted under the direct supervision <br /> of a licensed professional <br /> 21 Drilling <br /> Permits will be obtained, if necessary, for the borings before drilling begins The <br /> soil boring will be accomplished using a mobile mounted Geoprobe® Systems <br /> drilling rig, Model 5400, employing the use of a 1 25"hollow probe rods The <br /> contractor conducting the drilling will posses a valid C-57 license and proof of <br /> workman's compensation insurance <br /> All drilling equipment will be thoroughly steam cleaned before drilling begins to <br /> prevent the introduction of contamination from off site, and between borings to <br /> prevent cross contamination <br /> The borings will be logged under the direct supervision of a registered geologist <br /> using the Unified Soil Classification System The color, texture, moisture, plasticity <br /> (if applicable), consistency of the earth materials, pertinent soil or bedrock <br /> characteristics, and any evidence of contamination will be noted All water-bearing <br /> zones and the depths at which they are encountered will be noted on these logs <br /> All borings will be drilled in such a manner as to prevent cross contamination <br /> between strata Water samples will be taken at the soil/groundwater interface (if <br /> encountered), and the borings will then be terminated with a cement and three <br /> percent (3%)Bentonite mixture <br /> 2.2 Sod Sampling <br /> All soil sampling equipment will be thoroughly steam cleaned before and between <br /> sampling to prevent cross contamination Relatively undisturbed soil samples will <br /> be taken at intervals of not more than five feet (5') in order to evaluate the <br /> subsurface materials <br /> The soil samples will be taken using a Geoprobe core sampler with plastic liners <br /> The sampler will be pushed (Direct Push Technology) continuously by the <br /> hydraulically powered, percussion system <br /> 2 <br />
