Brian Klaus, LSP

Senior Geologist I

Mr. Klaus is a Senior Geologist and project manager with over ten years of experience in environmental assessment, remediation, and brownfield redevelopment support. Mr. Klaus has conducted or managed due diligence projects of commercial, industrial, residential, and retail properties throughout New England, New York, and New Jersey. Additionally, Mr. Klaus has worked on various environmental cleanup projects from preliminary due diligence support activities through active remedial design, and completion of site remediation and redevelopment.

representative projects
  • Urban Redevelopment, South Boston, Massachusetts. Managed overall environmental services in support of redevelopment across multiple parcels encompassing approximately 12 acres and multiple environmental releases. Managed waste characterization and waste profiling efforts, Massachusetts Contingency Plan (MCP) reporting, and environmental investigation activities, all of which were performed on an expedited schedule to meet property redevelopment goals. In addition to environmental releases being regulated by the Massachusetts Department of Environmental Protection (MassDEP), portions of the project were subject to USEPA Toxic Substances Control Act (TSCA) regulations due to elevated levels of polychlorinated biphenyls (PCBs) present in environmental media.
  • Retail Center, Enfield, Connecticut. Implemented remedial responses to a Connecticut Department of Energy and Environmental Protection (CT DEEP) Significant Environmental Hazard (SEH), created by a chlorinated solvent plume located beneath an active restaurant after the original consultant’s remedy was unsuccessful. Response actions included an investigation to properly identify the source zone and source extents, design and installation of a sub-slab depressurization (SSDS) system, and the design and installation of an in situ chemical oxidation (ISCO) injection system infrastructure beneath the restaurant. Chemical injections and air sparging events were completed to address the source zone of contamination. Work was completed on an aggressive schedule to reduce the impacts to restaurant operations. Work included remedial system infrastructure installation, abatement of asbestos-containing building materials (ACBM), chemical injections, air sparging, environmental monitoring, and regulatory coordination and reporting.
  • Demolition and Redevelopment Support. Managed numerous hazardous building material surveys (ACBM, lead-based paint [LBP], and PCBs) in support of demolition, as well as in support of due diligence for real estate transactions. Surveys often conducted on an aggressive schedule to meet client deadlines. Surveys included subsequent PCB substrate sampling and consulting on approaches for bulk product removal/remediation of PCB-impacted materials. Coordinated and oversaw abatement measures with strict timeframes.
  • Brownfields Cleanup Program, New York. Project manager for a 9-acre New York State Department of Environmental Conservation (NYSDEC) Brownfields Cleanup Program Site, located on one of the first oil storage and refining centers in the Northeast. The project included the design and implementation of a 25,000-cubic-yard soil in situ stabilization, and excavation and backfill of approximately 75,000 cubic yards of soil. Work included engineering design, development of an excavation and solidification sequencing plan to minimize and control vapors and odors, and installation QA/QC and validation. Work conducted to allow for redevelopment of property for an industrial client.
  • Environmental Consulting and Support, Massachusetts Municipality. Provided environmental support to a local municipality and its water treatment plant by monitoring contaminated groundwater near the town’s drinking water withdrawal wells. Provided recommendations relating to temporary shutdowns of certain drinking water wells and the impacts of off-site chemical plumes to the water treatment plant. More specifically, worked with the town to prevent 1,4-dioxane from entering the drinking water withdrawal wells and treatment plant influent.
