As a consultant, 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.
To advance the state of the practice, Denise provides litigation support regarding MTBE impacts at a number of release sites relative to a natural resource damage claim related to use and storage of gasoline. She also develops probabilistic cost analyses of environmental liabilities in support of litigation. Ms. Tripp has provided technical support for liability litigation regarding historic polychlorinated biphenyl releases at a recycled paper manufacturing facility in Wisconsin. She also provided technical analyses, including groundwater flow and transport model development, to support litigation regarding remediation cost allocation related to historic chlorinated solvent releases at an industrial facility on Long Island. She developed a performance monitoring plan to assess the effects of tunnel construction on groundwater flow and DNAPL in a fractured rock aquifer at a former manufacturing plant in upstate New York. Denise also managed long-term groundwater extraction and treatment system monitoring at a Superfund site in Massachusetts.
