� rr <br /> . Snuth Technology Corporation <br /> Quality Assurance/Quality Control Plan <br /> Revised February 1995 <br /> Product thickness is calculated by subtracting the depth to product from the depth to water In <br /> addition, water elevations are adjusted for the presence of fuel with the following calculation <br /> (Product Thickness) (8) +(Water Elevation) =Corrected Water Elevation <br /> NOTE The factor of 0 8 accounts for the density difference between water and petroleum <br /> hydrocarbons <br /> Newly installed wells will be allowed to stabilize for 24 hours after development prior to free product <br /> inspection <br /> An acrylic Surface Sampler will be used for visual inspection of the groundwater in order to note <br /> sheens (difficult to detect with the Interface Probe), odors, microbial action and sediments The <br /> sampler is calibrated in inches and centimeters for visual inspection of product thickness <br /> To reduce the potential for cross contamination between wells, the monitorings will take place in order <br /> from the least to most contaminated, if known Wells containing free product will be morutored last <br /> Between each well monitoring the equipment will be decontaminated <br /> Water level data collected from the wells will be used to develop a groundwater contour map for the <br /> project site Groundwater flow will be estimated to be perpendicular to equipotential lines drawn on <br /> the map <br /> W WdminlShe11slQAQC-97 DOC <br />
