During this sampling event, purging wells by balling was performed at the "B" and "C" casing wells Purging .yells by bailing involved using a 15-inch by 6 5-foot bailer and repeatedly bailing N%atei from the well casing until app:o%nnatcly thiee well Volumes of water had been rennoved The bailer was decontaminated befoic and after use with a liquid Alconox@ detergent wash, a tap water rinse, and a thorough final rinse with deronrzed water During bailing, periodic groundwater parameter readings were recorded onto the groundwater sampling data sheet These groundwater parameters included conductivity, salinity, temperature, and pH After recording the groundwater parameters, the purged water was transferred fiom five-gallon buckets or a 55-gallon drum to tine on-site 1,000-gallon polyethylene storage tank pending waste profiling and removal Groundwater Sampling Groundwater samples were collected at each monitoring well using a new polyethylene, disposable bailer The groundwater recovered with the bailer was transferred into laboratory-supplied sample containers as needed per each analytical method Upon collection, the sample date, time, and identification were written on the containers and on a chain-of-custody The sample containers were then placed in a sample cooler containing ice and transported, under strict chain-of-custody protocol, to the state-certified analytical laboratory for analysis • 2
