Fellows Dike Sampling Investigation

The Fellows Dike sampling investigation is needed to collect information regarding subsurface materials to support the planning and design for the proposed CDSRP. The investigation would be conducted within Valley Water property by the Fellows Dike area immediately south of Calero Reservoir. Activities would include conducting approximately 19 soil samples at 1 foot below ground surface, and 3 groundwater samples from 25-45 feet below ground surface. The investigation area would be accessed from existing paved or dirt roads. Soil samples would be collected utilizing a direct-push or Standard Penetration Testing (SPT) capable drill rig, which would drill approximately 4-inch diameter holes beneath ground surface. Approximately three temporary groundwater wells would be installed in three of the holes to collect the groundwater samples. Two additional soil samples would be collected from the planned location for the Bailey Fellows House, reaching depths up to 20 feet below ground surface. The house is proposed to be relocated as part of the CDSRP. After work is complete, all excavated areas would be backfilled with the existing soil and samples would be properly sealed and sent to a laboratory to be tested for potential hazardous materials. All excess soil cuttings and purge water would be placed in 55-gallon drums and disposed of off-site. Concurrently with the soil and groundwater sampling, pedestrian surveyors would collect asbestos, lead, and Polychlorinated Biphenyl samples of all on-site structures, except the Bailey Fellows House.
