1 <br /> four well casing volumes were purged, and the pH, specific conductance, and temperature <br />' had stabilized, or five well volumes had been evacuated If low yield monitoring wells <br /> evacuated to dryness after the removal of less than three casing volumes, such low yield <br />' wells were allowed to recover for a minimum of two hours If the well recovered to 80% <br /> of its original water level after two hours, a groundwater sample was collected <br /> Otherwise, the well was allowed to recover up to 24 hours prior to sampling If <br />' insufficient water recharged after 24 hours, the monitoring well was recorded as dry for <br /> the sampling event <br />' All field measurements were recorded in a waterproof field logbook Water sample field <br /> P g P <br />' data sheets were prepared to record the field data These data sheets were reviewed by <br /> the sampling coordinator when the sampling event was completed <br />' The pH, specific conductance, and temperature meter were calibrated each day before <br /> beginning field activities The calibration was checked once each day of sampling to verify <br /> meter performance All field meter calibrations were recorded in the field logbook <br />' Groundwater generated from well-purging operations was contained for temporary <br /> storage in 55-gallon drums All drums were labeled and stored onsite 1n a location <br />' designated by the client or client representative The sampler recorded the following <br /> information on the drum label for each drum generated <br />' Drum content (groundwater) <br /> • Source (well designation) <br />' Date generated <br />' Client contact <br /> • Project number <br />' Name of sampler <br /> The groundwater will be stored onsite for a maximum of 90 days Burlington will notify <br /> the client when the water is ready for removal <br />' A-3 <br /> E 1CT1102\102QR02 DOC <br />
