KLEINFEL E WHMS-IM14100111 Forward Inc. is completing a new waste treatment unit within WMU-G on the north side of the landfill. As a result, the line of wells which monitor the point of compliance along the north property boundary must be extended to monitor the new unit. Ground water elevation measurements over the last few years indicate that the ground water gradients frequently swing to the east and southeast in the southern part of the landfill. As a result, the present background well (MW -12/12B) is occasionally downgradient of the Eastern Ash Pit and WMU-F, and the eastern property boundary along Austin Road may not be monitored fully to the south of MW -13/13B. Kleinfelder proposes to install three new wells (MW -17 through MW -19) along the northern boundary downgradient of WMU-G, one new background well at the western edge of the property (MW -20), and one new monitoring well (MW -16) on the eastern property boundary south of MW -13/13B. Proposed monitoring well locations are shown on Plate 1. Details of the proposed construction of the wells are presented in the following scope of services. The installation will be in a phased approach. Phase 1 (MW -17, 18, 19) will be installed starting April 14 or 15. Phase 2 (MW -16 and 20) wells will be installed at a yet to be determined date. SCOPE OF SERVICES Drilling, Installing, and Developing Five Monitoring Wells Five borings will be drilled at locations shown on Plate 1. The borings will be drilled to approximate depths of 100 feet following the protocol described in Appendix A, Section A-2. A 4 -inch well will be installed in each boring, following the protocol described in Appendix A, Section A-3.1. Following installation, the wells will be developed to remove sediment and set the filter pack. The wells will be developed as described in Appendix A, Section A-3.2. The tops of the well casing will be surveyed as described in Appendix A, Section A-3.3. It is assumed that Forward Inc. will arrange for the wells to be surveyed. Following well installation, the new wells will be incorporated into the Post -Closure and Chapter 15 Monitoring Programs for Forward Landfill. Report of Findings Upon completion of the field activities described above, a report of monitoring well construction activities and observations will be prepared.
