Bryan Pitts, P.E. - Senior Managing Engineer - Environmental and Earth Sciences

Mr. Pitts is an environmental engineer with over 25 years' experience. He specializes in cost allocation and CERCLA cost recovery; historical waste management standard of care; assessment and valuation of environmental risks and liabilities; contaminant fate and transport; remedial investigation, design, construction oversight, and management; and environmental engineering analysis.

In addition, Mr. Pitts manages large, multi-disciplinary projects and provides technical expertise on a wide variety of environmental and related economic matters.

Mr. Pitts has extensive experience with many contaminant types (e.g., metals, NAPL, PAHs, perchlorate, pesticides, PCBs, PFAS, radionuclides, and VOCs) and industry sectors (e.g., chemical manufacturing, diecasting, electrical equipment manufacturing, flare making, mining and mineral processing, pesticide formulation, utilities, and waste disposal). He has studied, participated in remedy designs, and/or provided oversight of remediation activities and contractors at several former manufactured gas plants (MGPs), including a multi-year assignment as the resident engineer for remediation of a Cambridge, Massachusetts MGP, one of the largest Brownfields in the state. He has also consulted in insurance cost recovery, cost allocation, or toxic tort matters at over 60 other MGPs and numerous other hazardous waste sites. These matters often involved reconstructing historical manufacturing operations and waste management as well as evaluating environmental conditions, responses, and costs to address issues such as standard of care; expected/intended; contaminant source identification, causation, and timing; defense versus indemnity; regulatory (e.g., NCP) compliance; and remedy/cost reasonableness. He has worked in either a strategic advising or litigation support role on many of the nation's largest and most contentious MGP, PCB, sediment, wood treating, RCRA, and CERCLA sites.

The projects described below involve allocation of contamination and liability, insurance remedial cost recovery claims, estimation and evaluation of environmental response costs, hazardous waste site remedial oversight and investigation, assessment and valuation of environmental liabilities, toxic torts, and consulting/advocacy on various environmental matters.
