Measurements are obtained by <br />lowering the device into the weU until it indicates that the water surface has been encountered and by <br />measuring the distance from die top of the inside pipe to the probe. All of the measurements are <br />recorded to the nearest 0.01 foot; however, the manufacturer*! reported accuracy for the instruraent is <br />0.04 foot. <br />4.4 Water Samnlinn <br />All monitoring wells were sampled from suspected cleanest to most contaminiied according to the <br />following protocols. <br />rieiii mtfttti <br />Step 1: <br />Step 2: <br />Measure water level. <br />A stainless steel bailer was used to develop each monitoring well. A minimum of three <br />to five well bore water volumes 'vtre evacuated from each monitoring well prior to <br />sampling. <br />Step 3:Collect water samples. Water samples were collected using a stainless steel. A field <br />blank was collected during the sampling program. <br />Step 4:Store water samples and transport to PACE Laboratories, following all documentation and <br />chain of custody procedures. <br />Step 5:Qean equipment. Water level measurement equipment was cleaned with clean tap water <br />followed by deionized water rinse. <br />Upon complotion of a soil or ground water sampling a chain of custody was initiated. Chain of custody <br />records include the following information: project, project number, shipped by, shipped to, suspected <br />haard, sampUng point, location, field identificaUon number, date and time taken, sample type, number of <br />containers, analysis required, and sampler signature. As few people as possible handle the samples. <br />The chain of custody records were shipped with the samples to the laboratory. Upon arrival at the <br />laboratory, the samples were checked and signed in to the appropriate laboratory personnel. Laboratory <br />M.nrifi-.rinn numbers were noted on the chain of custody record. A copy of the chain of custody was <br />turned over to the project manager. <br />tv J! <br />ir m <br />1 <br />‘ <br />m <br />Thei <br />based <br />hydn <br />impU <br />This <br />Davit <br />Hydr <br />Revic <br />X <br />Danu <br />Geolc <br />c <br />Midw <br />clo.81
