fry <br /> RESNA Industries Inc. AINAMA <br /> r..; Quality Assurance/Quality Control Plan <br /> Revised November I992 <br /> To reduce the potential for cross contamination between wells, the monitorings will take place <br /> �- in order from the least to most contaminated, if known. Wells containing free product will be - <br /> F' monitored last. Between each well monitoring the equipment will be decontaminated. <br /> Water level data collected from the wells will be used to G: developa groundwater contour g map <br /> for the project site. Groundwater flow will be estimated to be perpendicular to equipotential <br /> lines drawn on the map. <br /> I0.0 WELL DEVELOPMENT PROTOCOL <br /> Groundwater monitoring wells will be surged and developed prior to setting the surface seal- <br /> E Approximately 10 times the volume of water in the casing will be withdrawn if possible.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 /> C VOLUME OF SCHEDULE 40 PVC PIPE <br /> Diameter (inches) I.D.
