} <br /> INTERI\�ONAL TECHNOLOGY CORPORATION <br /> The wells will be purged of three well volumes of groundwater utilizing a decontaminated <br /> bailer or pump (depending on volume of water to be removed). A water sample will be <br /> 5i collected from each well when the water reaches 80 percent of its initial level. If the wells <br /> are slow to recover, samples will be collected after the wells have stabilized. If the wells are <br /> j.. found to contain free product, a sample for laboratory analysis will not be collected. <br /> Measurements of temperature, conductivity, and pH will be measured and recorded to verify <br /> well stabilization. <br /> r <br /> Groundwater will be sampled using a new Voss Technologies disposable bailer. Each water <br /> sample will be placed in appropriate containers supplied by the laboratory. Care will be <br /> 1 taken that no headspace is present in sample bottles which will be analyzed for volatile <br /> organic compounds. Once the samples are collected, the bottles will be placed in "ziploc" <br /> w <br /> bags and sealed with security tape. The samples will be stored in a chilled ice chest until <br /> delivery to the laboratory. <br /> In addition to the groundwater samples, a quality assurance field blank will be analyzed in the <br /> same manner as the other sample. The field blank will consist of filling identical sample <br /> + bottles with distilled water in the field and treating them in the same manner as the rest of the <br /> samples. <br /> i.. <br /> The water samples will be analyzed by a California state certified analytical laboratory. The <br /> 7 samples will be analyzed utilizing the methods and detection limits shown below: <br /> Sample Detection Limit <br /> Analysis Name Container Method (ppb) <br /> r (BTEX) <br /> benzene Three 40ml EPA Modified .3 <br /> toluene volatile organic 8020 .3 <br /> ethyl benzene vials with HCI .3 <br /> total xylenes .6 <br /> w <br /> } <br /> L <br /> i MZ"-N-9Z04QM83.NER <br />
