Mr. Howard Hold <br /> August 16, 2004 <br /> Page 2 <br /> • Shallow Completion: approximately 500 feet south of the south pond (south of <br /> Littlejohns Creek). <br /> As a result of the opposition by the property owner(Sousa)who owns property where four of <br /> the five monitoring wells were initially sited, significant adjustments to the planned drilling <br /> program have been required. The new proposed locations are shown on Figure 1. <br /> The proposed wells are now sited on land owned by Kruger Foods, Inc. The objectives for <br /> monitoring at the new locations include: <br /> • M W5A: install a new shallow zone monitoring well at a location upgradient and <br /> somewhat cross-gradient of the ponds;determine whether the location of M W5A was <br /> impacted by historical operations; assess whether MW5A may, in the future due to <br /> the more recent tendency for the ground-water flow direction to be northwesterly, <br /> provide a more suitable background monitoring well. <br /> • MW6A: install a shallow zone monitoring well downgradient of the ponds. <br /> Monitoring results for this location would provide an indication of to what extent <br /> impacts have occurred in the vicinity of the ponds at a location further removed from <br /> the ponds than existing shallow zone wells(e.g., MW I and MW3A). A monitoring <br /> well at the revised location is also anticipated to be beneficial for further assessing <br /> corrective action measures and for inclusion in the corrective action monitoring <br /> program. <br /> • M W6B: install a deep zone monitoring well to the north (e.g.,at a location presently <br /> cross gradient of the observed direction of ground-water flow in the deep zone). The <br /> proposed location to the north would provide additional gradient control at a location <br /> away from facility pumping and world also provide additional information to further <br /> refine the apparent limited impact of historical operations on the deep zone. <br /> Test Holes <br /> Test holes will be drilled at each of the two well locations using mud rotary drilling methods. <br /> The first test hole (at the MW613 well location)will be drilled to a depth of approximately <br /> 250 feet. The test hole borehole diameter will be 8-3/4 inches;cuttings samples will be <br /> collected at 10-foot intervals or when there is a change in lithology. Following drilling, <br /> geophysical logs will be run in the borehole for Spontaneous Potential and a Resistivity suite <br /> (long and short normal and single point). MW613 will be constructed in the test hole. Final <br /> well designs will be based on interpretation of the geophysical log, lithologic data,and prior <br /> geologic information for the site. <br /> Following the construction of M W6B,the drilling rig will move over approximately 10 feet <br /> and drill a 12-1/4-inch diameter borehole to approximately 150 feet for the construction of <br /> MW6A. Geophysical logging will not be conducted in the MW6A borehole since the <br /> logging of the M W6B borehole should provide adequate definition of subsurface conditions <br /> at this monitoring location. Following the construction and development of MW6A and <br /> M W6B,the drilling rig will move to the M W5A site. The test hole at this location will be <br /> constructed to a depth of about 150 feet. Upon reaching the target depth, a geophysical log <br /> will be conducted as described previously for the M W6B site. <br />
