Michael Leacox <br /> Page 8 of 11 <br /> compaction/permeability properties of the clay. Assisted contractor during excavation of <br /> clay materials to ensure that quality assurance/quality control requirements were met. <br /> Water supply study, Tehachapi, California - Mapped site geology and interpreted <br /> geologic structure of a fault-controlled canyon adjacent to the Garlock fault. Concerns <br /> included the influence of geologic structure upon groundwater movement and <br /> groundwater recharge to a layered alluvial aquifer. <br /> Long-term jail siting study, Orange County, California - Mapped geology of five <br /> areas in the Santa Ana Mountains as part of an environmental impact report to assess <br /> the potential for the sites to be developed as a large jail facility. Concerns included the <br /> relationship of possible landslides, faults, geologic structure, and alluvium depths to <br /> proposed cut and fill slopes and proposed building locations. <br /> Low-level radioactive waste siting repository study, San Bernardino County, <br /> California - Designed construction and installation criteria for the placement of <br /> thermocouple psychrometers and tensiometers horizontally away from 6-foot-diameter, <br /> 40-foot-deep caisson for vadose-zone monitoring. <br /> Dry cleaner solvent investigation, Merced, California - Managed, designed, and <br /> implemented field investigation to evaluate the lateral extent of groundwater and soils <br /> impacted with PCE. Investigation included a soil gas survey and the installation of <br /> groundwater monitoring wells. Source concerns included transport through the sewer <br /> system and soils. <br /> Dry cleaner solvent investigation, Sacramento, California - Managed project which <br /> included evaluation of the potential for the public sewer system to have contributed to <br /> the transport of PCE found in a nearby production well. Investigation included a soil gas <br /> survey and drilling of soil borings. <br /> Dry cleaner solvent investigation/site characterization investigation, Davis, <br /> California - Managed and designed a project to evaluate the lateral extent of <br /> groundwater impacted with perch Ioroethene. Investigation included installing soil <br /> borings and monitoring wells, and conducting a soil gas survey. <br /> Remedial investigation/feasibility study, Davis, California - Managed investigation to <br /> evaluate impacted soil and groundwater for a site slated for development that <br /> encompassed one city block. Project required installing 12 monitoring wells and <br /> numerous soil borings, and conducting a soil gas survey. Included was an evaluation of <br /> remedial alternatives for identified impacted groundwater and soil, and cost estimates for <br /> feasible alternatives. <br /> Deep well installation, Lodi, California - Supervising Geologist during the drilling and <br /> installation of a 4,000-foot-deep injection well. Project included drill-stem testing of <br /> formation fluid to evaluate TDS levels in the target formation. <br /> Technical feasibility study, Lodi, California - Prepared preliminary technical feasibility <br /> study evaluating potential subsurface geologic structures to complete a proposed <br /> injection well to receive brine wastes from the plant. Identified the Domengine <br /> sandstone at a depth of 3000 feet, which is capped by overlying and underlying <br /> formations of lower permeability. <br />
