Environmental Assessments & Environmental Impact Studies
SCA Environmental, Inc. has performed Environmental Assessments for a wide spectrum of clients and projects including local municipalities, the federal government, private developers, and private clients throughout California and the Western United States.
SCA draws on a depth of experience to select the most cost-effective investigation methods for any specific project. SCA's goal is to provide data to the Client and regulatory agencies in an understandable, organized fashion; and to scale the investigation to the proposed uses of the data.
SCA's site investigations provide relevant, reliable information for construction projects, risk assessments, remedial actions, and real estate transactions.
Examples of Site Assessment projects performed by SCA include:
- Site Assessment at D-Q University, a former Army radio station, where diesel and solvent sources had impacted subsurface conditions. SCA was hired to characterize the impacts to soil and groundwater at the site. SCA performed a ground-water investigation which included soil gas surveys, direct-push Hydropunch sampling, and installation and sampling of monitoring wells.
- Site Assessment at the Bernal Dwellings Housing project which included the demolition of 12 multi-story apartments containing 200 units of public housing, and replacement with low-rise townhouse style residences. SCA was retained to provide a Phase 1 Environmental Site Assessment, evaluate possible on-site soil and groundwater contamination, and to devise mitigation measures. SCA's historical research indicated that a tannery, which performed chrome tanning and leather dyeing, had operated on-site from 1883-1941. In addition, there had been fuel oil storage tanks for powering pumps and several undocumented water supply wells existed on the property.
- SCA is providing environmental services on multiple phases of the Golden Gate Bridge Lead Clean-up & Seismic Retrofit Project, including preparation of a Site Specific Health and Safety Plan, Lead Compliance Plan, and Mitigation Plan as well as provided asbestos and lead awareness and HAZWOPR training and air monitoring services. The phased project includes using a Guzzler truck-mounted vacuum to remove lead-contaminated sand under the bridge, then excavation and removal of several thousand cubic yards of lead-contaminated soils and soils with naturally-occurring asbestos.
