1 , <br /> 1 During this sampling event, purging wells by bailing was performed at the "B" and "C" casing wells <br /> Purging wells by bailing involved using a 1 5-inch by 6 5-foot bailer and repeatedly bailing water from <br /> ' the well casing until approximately three well volumes of water had been removed Purging and <br /> pumping was performed with a 2" Grundfos "Reda-flo" submersible pump The pump was attached to a <br /> 1 hose and reel system and powered with 110 volts of electricity supplied at the facility The bailer and <br /> pump were decontaminated before and after use with a liquid detergent wash (Alconox®), a tap water <br /> 1 rinse, and a thorough final rinse with de-ionized water <br /> ' During purging, periodic groundwater parameter readings were recorded onto the groundwater sampling <br /> data sheet These groundwater parameters included conductivity, salinity, temperature, and pH After <br /> 1 recording the groundwater parameters, the purged water was transferred from five-gallon buckets or a 55- <br /> gallon drum to the on-site 1,000-gallon polyethylene storage tank pending waste profiling and removal i <br /> I <br /> Groundwater Sampling <br /> 1 Groundwater samples were collected at each monitoring well using a new polyethylene, disposable <br /> bailer The groundwater recovered with the bailer was transferred into laboratory-supplied sample <br /> ' containers as needed per each analytical method Upon collection, the sample date, time, and <br /> identification were written on the containers and on a chain-of-custody The sample containers were then <br /> ' placed in a sample cooler containing ice and transported, under strict cham-of-custody protocol, to the <br /> state-certified analytical laboratory for analysis <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> i <br /> i <br /> 1 2 <br />
