' 5.0 GROUNDWATER SAMPLING <br /> tFollowing the development, the groundwater monitoring well (MW-4) was sampled by <br /> BSK personnel <br />' Prior to sampling, the depth to water in the well was measured utilizing an electric <br /> sounding tape The well was then purged of at least three well volumes Purging was <br />' accomplished by use of a bladder pump After removal of each well volume, parameters <br /> were measured utilizing a field meter The parameters measured included pH, <br /> conductivity and temperature Consistency of these measured properties indicate that <br /> fresh water is being drawn from the aquifer A well field log was maintained for the well <br />' (see Well Field Log presented on Plate 9) <br />' The groundwater removed during purging was placed into 55-gallon DOT 17 E/H drums <br /> and labeled with the Well I D number, date and purged water <br />' The groundwater was sampled with a Teflon TM point source bailer The samples were <br /> placed into appropriate sample containers with preservatives added and labeled The <br /> samples were stored in a cooler with ice and delivered to the BSK State-certified <br />' Analytical Laboratory, located in Fresno, California Prior to and after sampling, the <br /> sampling equipment was washed with laboratory grade detergent and washed with a <br /> high-pressure, high-temperature cleaner <br /> 1 <br /> I <br /> BS14C <br /> 1y4(ll il�f 5 <br />
