RFSNA Industries Inc- AMA <br /> !_FQuality Assurance/Quality Control Plan Q r <br /> Revised November 199'_ <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 o tanning free product will be <br /> �f_ monitored last. Between each well monitoring the equipment will be decontaminated. <br /> F <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 bendicular to <br /> penile egvipoteatial <br /> lines drawn on the map. <br /> m' 10.0 WELL DEVELOPMENT PROTOCOL <br /> Groundwater monitoring wells will be surged and developed prior to setting the surface seal. <br /> "1 Approximately 10 times the volume of water in the casing will be withdrawn if possible.
