<br /> ' FIELD WORK TUESDAY, APRIL 7, 1992
<br /> Operations commenced at 8 AM Pulled auger flights from hole
<br /> ' and completed well as follows : Ran 2" screw joint PVC,
<br /> schedule 40 from surface to 86 ' (Figure 3) . From bottom up,
<br /> screw type bottom cap, . 02" perforated liner from 86 ' to 71 '
<br /> ( 151 ) , sand-gravel packed well with Lonestar 2/12 sieve mix
<br /> ' to 671 , 4 ' above the perfs . , placed 3 ' of hydrated bentonite
<br /> pellets, from 67' to 641 , water table estimated at 741 .
<br /> Cemented casing from 64' to 1 ' below surface with a tremie
<br /> pipe, pumped in cement using a slurry of 2 % bentonite .
<br /> I t Surface equipment described at end. Moved to MW #1 and
<br /> cemented as previously described.
<br /> t Linda Turkette, EHD, was on site to witness cementing
<br /> operations .
<br /> ' Moved to MW # 3 , Surface location moved about 6 ' west of
<br /> proposed location for convenience (Figure 1 has been
<br /> corrected for well locations) . About 2 ' of rock rubble and
<br /> silt fill were removed at the surface. From 2 ' to 41 : fill
<br /> material . From 4 ' to 391 : light brown to reddish tinged
<br /> clay, moist with clumps of cuttings to 2" to about 241 ,
<br /> clumps of cuttings to about 3" in length from 24' to 39 . No
<br /> ' hydrocarbon odor at any point. From 39 ' to 441 : dense,
<br /> brownish clay, almost dry, no odor, very fine cuttings .
<br /> From 44' to 471 : brownish clay as above grading to brownish
<br /> ' silt. Sample # 1 , at 47 ' to 48 1/21 , brownish silt and
<br /> dense brown clay in core, carbon inclusions . From 47 ' to
<br /> 52 ' : dense, brownish clay as above, cuttings to 1 "size.
<br /> ' Sample # 2, at 52 ' to 53 1/2 ' , brownish, dense, silty clay,
<br /> micaceous . From 52 ' to 571 : dense, brownish clay as above,
<br /> less mica From 57 ' to 621 : brownish clay as above, sticky
<br /> and damp, cutting clumps to 6" long . Sample # 3 at 62 ' to
<br /> ' 63 1/21 , brownish clay, damp, dense, possible hydrocarbon
<br /> odor at 63 1/2 ' . From 62 ' to 671 : dense, brownish clay as
<br /> above . Sample # 4 at 67 ' to 68 1/21 , dense, brownish clay
<br /> ' grading to clayey silt at 67 1/21 , possible hydrocarbon
<br /> odor. From 67 ' to 72 ' : brownish clay as above, large balls
<br /> indicating water content, no silt in surface returns Sample
<br /> # 5 at 72 ' to 73 1/21 , very silty, brownish, wet clay, water
<br /> table fudged to be at 721 . Silty clay on bit From 72 ' to
<br /> 841 . brownish, silty clay on bit at 841 , cuttings brownish
<br /> silty clay probably from above bottom. Attempted to run 2"
<br /> casing, would not go to bottom, pushed to 83 1/2 ' Well
<br /> completion as follows : Ran 211 , Schedule 40, screw point PVC
<br /> to 83 1/2 ' (Figure 4) . From bottom up, screw type bottom
<br /> cap, . 02" perforations from 83 1/2 ' to 68 1/2 ' (15 ' ) , sand-
