On February 23, 2000 Mr Steve Broadway (Wege Geotechnician) and David Pitman (Pitman Well Service) followed WEGE's standard QA/QC procedures as outlined in the previous pages, with the following exceptions Bold items or comments are where our geotechnzcian varied from our standard published QA/QC methods. I Inspection of well, opened traffic box lid, removed fluids from traffic boxes 2 Open well, removed thermos type watertight cap to allow well to stabilize 3 Open remaining wells as above and let stabilize 4 Take depth to top of water reading in the annular area between the casing and the extraction pipe, using a Solinst meter to the nearest 0 01-foot reading measured from survey mark at top of casing Geotechnician measured depth to bottom of wells during the February 23, 2000 sampling round and found the following depths below top of casing (MWI = 48 80', MW2 =49 50', MW3 = 49 22') 5 Remove i inch PVC stinger (pumping extraction pipe) from well, place onto clean rack and obtain sample of water in well prior to any purging Water sample measured with Hydac meter calibrated at the site 6 I inch PVC stinger placed in tree to prevent touching surface area and likely areas of residual contamination 7 Place 1-inch PVC stinger back into well and purge three borehole/well volumes 8 Remove 1-inch PVC stinger and place on clean racks while hand bailing/sampling well Used a tree for the clean rack to hold while hand bailing/sampling well, both samplings 9 Obtain water sample with new disposable PVC bailer Measure sample for pH, temperature and conductivity with Hydac meter Obtained water sample with dedicated PVC bailer. 10 Baal one gallon of water from well with dedicated bailer mentioned above Obtain sample for pH, temperature and conductivity with Hydac meter Continue to hand bail and obtain measurements every one-gallon of water bailed until pH, temperature and conductivity stabilize 11 Each well had a total purge volume of between 12 and 23 gallons prior to obtaining samples for certified Iaboratory analysis 12 At completion of purging well, obtain depth to water measurement to calculate when recovery to 80% has been achieved Geotechnician modified this by tying a knot in the bailer string to mark the location where the top of casing was in reference to the first bail of water prior to any purging. Used this to ,justify recovery to 80% 13 Obtain samples for certified laboratory using the dedicated bailer and slowly decanting the sampled water into laboratory supplied clean 40 cc VOA's containing HCL as a preservative with no headspace 14 Obtain pH, Conductivity and Temperature of the sample water Geotechnician did not do. He saved, as samples, the next bailer filled after stabilization. 15 Label the VOAs and place into ziplock baggies prior to placing the samples in ice chest containing ice
