i <br /> r <br /> RESNA Industnes Inc <br /> Quality Assurance/Quality Control Plan <br /> Revised November 1992 <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 /> ' 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 protect site. Groundwater flow will be estimated to be perpendicular to equipotential <br /> ' lines drawn on the map. <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 ' Approximately 10 times the volume of water in the casing will be withdrawn if possible.
