H 1 . KLEINFELDER & ASSOCIATES File: W-2022-1/11:312 June 19, 1986 Page 7 Well 2 was set up in accordance with Subchapter 15 requirements. First, 30 feet of 4 -inch diameter slatted PVC pipe was inserted followed by 20 feet of solid PVC pipe casing. The casing was packed in sand to a depth of approximately 19 feet below the ground surface. A Bentonite pellet seal was placed from 19 to 14 feet. The remainder of the boring will be grouted to the surface and a locking well cover will be placed over the PVC pipe surface. Drilling at Wells 1 and 3 was stopped a t 90 es were covered until it was determined whether eto�developtdevelopThe orextend them to a greater depth. It is currentlype to grout and develop all three wells at the same time oncethey are completed. Subsequent to the above report, an attempt was made to install a deep monitoring well. The borehole was drilled to a total depth of 225 feet, no free water was encountered In the boring. The following discussion is taken from a September 27, 1985 retort: As reported in our June 7, 1985 report, three monitoring well borings were placed around the proposed ponds. At that time, only one of those borings encountered ground water with a perched water condition at approximately 29 feet below the surface, near the northeast corner of pond B. This boring was developed into a monitoring well. Our scope in this work was to attempt to install a deep exploratory boring and, if water was encountered, set un a monitoring well down -gradient of ponds A and B. The -- exploratory boring was drilled on August 20 and 21, 1985 by I LH111 No free ground water was encountered in Wells 1 or 3, however, some minor seepage of water was noted in Well 3 in the sandy layers located above the clay. The seepage was so little, however, that no free water was noted during the period our crews were at the site. Ground water was encountered at a depth of approximately 29 feet in Well 2. We understand that in the production well drilled for the existing facility, ground water was encountered at over approximately a 250 -foot depth and rose to within approximately 50 to 60 feet of the surface. If our borings were to penetrate this clay layer, it is likely that ground water would rise to similar depth as that of the production well. It is our opinion that ground water encountered in Well 2 is a perched ground water table resting on the clay layer. Well 2 was set up in accordance with Subchapter 15 requirements.
