<br /> the landfill. The RWQCB recently rescinded the waste discharge requirements and the
<br /> site is scheduled for construction.
<br /> Landfill expansion sites, Corona and Saugus, California - Managed and performed
<br /> geotechnical, geological, and hydrogeological evaluation of proposed expansion areas
<br /> for existing landfill. Projects included geologic mapping, air-photo interpretation,
<br /> borehole packer permeability testing, groundwater assessment, geophysical surveys,
<br /> and clay liner source evaluation.
<br /> Landfill monitoring plan, Saugus, California - Implemented groundwater and
<br /> unsaturated zone monitoring plan at an existing landfill and proposed expansion areas to
<br /> conform with California Administrative Code Title 23, Chapter 3, Subchapter 15.
<br /> Installed groundwater monitoring wells to 380 feet, vadose zone wells, lysimeters, and
<br /> neutron-probe access holes.
<br /> Groundwater supply project, Westley, Stanislaus County, California - Conducted an
<br /> evaluation of groundwater supplies in the Westley area to determine the potential impact
<br /> of proposed residential development. As required by Stanislaus County, the project
<br /> included an assessment of regional and local groundwater quality and quantity,
<br /> groundwater recharge and storage, flow patterns, and current groundwater usage. Local
<br /> geologic and hydrogeologic conditions were also evaluated. Provided recommendations
<br /> for water supply well locations, construction details, and potential groundwater treatment
<br /> options.
<br /> Groundwater supply project, Grayson, California - Conducted hydrogeologic study to
<br /> evaluate the potential impact of proposed residential development on groundwater
<br /> resources in the Grayson area. Investigation included a review of existing hydrogeologic
<br /> and geologic data to evaluate groundwater quality, quantity, flow patterns, recharge and
<br /> discharge, and current groundwater usage. Project also included estimating a water
<br /> balance for the proposed development, and estimating the development's impact upon
<br /> groundwater supplies.
<br /> Solid waste assessment test, Rancho Cordova, California - Project Manager of
<br /> SWAT investigation for a Rank 2 landfill. Project included preparation of a SWAT
<br /> proposal to be approved by appropriate regulatory agencies. Investigative techniques
<br /> included installation of deep monitoring wells through dredge tailings using air-
<br /> percussion drilling techniques, collection of surface and groundwater samples, and
<br /> collection of vadose zone soil samples.
<br /> Landfill construction, EI Sobrante Landfill, Riverside County, California - Onsite
<br /> geologist during construction of Class III landfill. Responsibilities included assisting
<br /> contractor in implementing landfill design criteria, and groundwater, vadose-zone, and
<br /> leachate monitoring plans.
<br /> Landfill access road, Riverside County, California - Conducted geologic investigation
<br /> to characterize site geology along a 1.3-mile-long access road. Project included use of
<br /> seismic refraction geophysics to assess the rippability of bedrock cuts up to 55 feet, as
<br /> well as foundation design criteria for a 5-span bridge.
<br /> Clay liner source investigation, EI Sobrante Landfill, Riverside County, California -
<br /> Conducted geologic investigation that identified onsite source of clay for use as a liner.
<br /> Investigation included extensive field mapping and laboratory testing to characterize the
