Document Description
The Department of Water Resources (DWR) South Central Region Office will conduct soil investigations for potential work in the Milburn Pond rea. Two geologic investigation methods will be used, sonic drilling and excavation of test pits. Sonic drilling will be conducted in approximately four locations on the existing Milburn Pond berm and in four locations in a potential borrow area approximately 4,000 feet west of the berm. The drill will be about 8 inches in diameter. Drilling depths on the berm will be up to 30 ft from the top of the existing ground surface; drilling depths at the other location will be up to 20 ft from the existing ground surface. After each hole is drilled, and before the rig moves to the next drilling location, the hole will be backfilled with material from the drill cuttings. The remaining drill cuttings will be either spread on site or will be disposed of in an appropriate offsite location. No drilling holes will be left open overnight. Test pits will be excavated in approx. 12 locations in the potential borrow site area. Each pit will be up to 15 ft dep, 20 ft long, and 5 ft wide. All test pits will be backfilled and compacted with a backhoe bucket and will be wheel-packed to match the existing grade. The pits will be backfilled after samples are collected and before excavating the next pit. At the end of the work, areas used for temporary storage of materials will be returned to the original grade and contoured to match the surrounding area. At all sites, soil samples will be collected every 5 ft from the ground surface. In the event of unexpected drilling issues or environmental concerns, exact drilling and test pit locations may be adjusted by the DWR geologists, Engineer, or Environmental Scientist during the work. It may be necessary to add more drilling locations depending on the visual observation of the completed drill holes; additional locations will be determined by the Engineer and Environmental Scientist.
