SEI has conducted numerous Phase 1 Environmental Site Assessments (ESA’s) per ASTM Standard 1527-13, Preliminary Environmental Assessments (PEA’s) for over 20 school sites per DTSC requirements, subsurface investigations (Geotechnical, Geologic and Environmental), soil and groundwater remediation, installation of soil borings and monitoring wells, and mitigation of geological and environmental issues. Our state-registered geologist, registered environmental property assessor (REPA) and certified engineering geologists are experienced in a wide variety of subsurface investigatory methods such as soil gas sampling, groundwater and vadose zone monitoring well installation, and shallow groundwater probe sampling. They also employ subsurface contaminant fate and transport models where appropriate to support investigations and risk assessments. SEI’s geologists are experienced in aquifer testing and groundwater modeling using the latest software applications. Our staff is experienced in soil and groundwater remediation technologies including; excavation and disposal of impacted soil, soil vapor extraction (SVE), bioremediation of soil and groundwater, combination airsparging and SVE, pump and treatment of groundwater. SEI’s QSD/QSP’s also prepare Storm Water Pollution Prevention Plans (SWPPP) and Spill Prevention Control & Countermeasure (SPCC) Plans.
SEI’s Environmental/Construction Department is experienced in cleaning out and rebuilding sumps, UST removals, AST installations, SWPPP implementation and restoration projects, and the removal and disposal of structures at private, public, and industrial, facilities. This has included the removal of sludge from the bottom of sumps, replacement of non-draining material, the removal and disposal of asbestos containing materials (ACMs), lead-based paint contaminated soil and general rubbish and vegetation at small residential and commercial facilities. Our construction managers are experienced in obtaining demolition permits, satisfying the local Air Pollution Control District (APCD) requirements, and general safety practices to complete the projects quickly and cost-effectively.
