Denise Tripp is a Senior Consultant based in Massachusetts with more than 35 years of experience focused on environmental assessment and remediation and litigation support for clients in the paper, petroleum, nuclear power, and manufacturing industries in the United States.
Denise's practice focuses on technical analyses related to hydrogeologic factors that affect groundwater flow and contaminant transport from hazardous waste disposal sites in support of litigation and remediation under a variety of federal and state regulations. Her areas of expertise include the application of groundwater flow and chemical transport models to evaluate regional and local flow regimes, hypothetical and historic releases, and remedial alternatives; statistical analysis of environmental data; and the development and management of environmental databases. Denise is a Certified Six Sigma Black Belt with experience applying Six Sigma principles to evaluate and improve water treatment plant operations. Her geotechnical experience includes the design and analysis of shallow and deep foundations and laboratory rock and soil testing.
Examples of her numerical modeling work include the development of pre and postconstruction groundwater flow models to support remedial design and redevelopment of a former industrial area to address to coastal flood protection, groundwater flow modeling of a municipal landfills to support remedy performance assessment, and groundwater flow and transport model development to support remediation cost allocation related to historic chlorinated solvent releases at an industrial facility on Long Island. Examples of her litigation support experience includes technical analyses regarding Methyl tert-Butyl Ether (MTBE) impacts to groundwater at a number of gasoline storage sites relative to a natural resource damage claim, development of probabilistic cost analyses of environmental liabilities, and technical analysis regarding historic polychlorinated biphenyl (PCB) releases at a recycled paper manufacturing facility in Wisconsin. Examples of her work to support site remediation include developing a performance monitoring plan to assess the effects of tunnel construction on groundwater flow and dense non-aqueous phase liquid (DNAPL) migration in a fractured rock aquifer at a former manufacturing plant in upstate New York and developing/implementing a plan to evaluate background arsenic concentrations in groundwater at a former municipal landfill in central Massachusetts.
