r FIELD PROCEDURES Site Safety Plan This plan describes the safety requirements for field work performed at the site The site safety plan is applicable to personnel of RESNA Industries who perform the field work. A copy of the site safety plan is available for reference by appropriate parties during the work The on-site representative of RESNA Industries acts as the Site Safety Officer Groundwater Sampling The static water level in each well was measured to the nearest 0 01 foot with a Solinst electric water-level sounder cleaned with a laboratory-grade, non-phosphatic detergent and deiomzed water before use in each well A clean bailer was used to obtain a sample from the surface of the water in the well for subjective analysis of hydrocarbons The sample was retrieved and visually examined for floating product, sheen, color, and clarity Approximately 3 well volumes of groundwater were purged from the wells using pre-washed bailers. The bailers were cleaned with a laboratory-grade, non-phosphatic detergent and water before use in each well. The wells were purged until withdrawal was of sufficient volume to result in stabilized pH, temperature, and electrical conductivity of the water, as measured by portable meters calibrated to a standard buffer and conductivity standard. The wells recovered to more than 90 percent of the static water level within 5 minutes of turning off the pump The groundwater purged from the wells was temporarily stored in 17-E, steel, 55-gallon liquid waste drums approved for this use by the Department of Transportation Hydrochloric acid (or other appropriate chemical) was added to the sample vials as a preservative A sample of the formation water then was collected from the surface of the water in each of the wells with disposable clean Teflon bailer and slowly transferred to laboratory-cleaned sample containers.
