' RESNA Industnes Inc <br /> QuaLty Assurancc/Quality Control Plan <br /> Reviscd November 1992 <br /> To reduce the potential for cross contamination between wells, the monitorings will take place <br /> m order from the least to most contaminated, if known. Wells containing free product will be <br /> ' monitored last. 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 <br /> for the project site Groundwater flow will be estimated to be perpendicular to equipotential <br /> lines drawn on the map. j <br /> 10.0 WELL DEVELOPMENT PROTOCOL <br /> Groundwater monitoring wells will be surged and developed prior to setting the surface seal. <br /> Approximately 10 times the volume of water in the casing will be withdrawn if possible. Casing <br /> volumes will be calculated in the following manner: <br /> VOLUME OF SCHEDULE 40 PVC PIPE <br /> Volume <br /> "Diameter (inches) LD (inches) <br /> Gal/linear feet <br /> ' 2 2067 0.17 <br /> 4 4 026 066 <br /> S <br /> VOLUME OF OPEN BOREHOLE AND ANNULAR SPACE BErINEEN CASING,ANE3}HO� <br /> ' 'Holen VolumelLinear Feet of Hole Nominal Volume/Linear Feet of <br /> biam ter <br /> Casing' -Annular Space' `ti` L <br /> (inches) ; <br /> Diameter' < `, <br /> Gallons Cubic Feet iinchesk Gallons Cubic Feet <br /> 725 2 14 029 2 1 91 026 <br /> ' <br /> 825 278 037 2 255 034 <br /> 1025 4.29 057 2 406 0.54 <br /> 1025 429 057 4 346 046 <br /> 1225 613 082 4 530 071 <br /> Annular volumes will be multiplied by 30%to account for porosity of filter pack <br /> QAQCIM FKL 8 <br /> I <br />
