Retained by the Kasper (1977) Irrevocable Trust to provide expert analysis of groundwater contamination and litigation support regarding costs associated with the development of a RI/FS at the American Drive-In Cleaners perchloroethylene site in Levittown, New York. NYSDEC had taken more than 13 years to develop the RI/FS and final Record of Decision for the site. Contamination resulted from leaky drainage tiles and was spread in the groundwater by nearby groundwater pumping wells. In addition, excessive costs associated with oversight and management of the site by NYSDEC and EPA had accrued, and the remedial selection process had resulted in a solution for which costs would exceed $5 million.

Directed development of a (SAP) for evaluation of sediments along canals and waterways associated with a major refinery in Argentina where a high degree of hydrocarbon contamination in the water at a nearby yacht club was resulting in a bloom of Microsystis aeruginosa (cyanobacteria with hepatoxins).

Served as project manager for a criminal investigation directed by EPA Region 10 as a result of the removal from a CERCLA site of 660 yd3 of potentially contaminated soil. Soil was disposed of at a commercial topsoil facility near Maple Valley, Washington. Because these soils were not sampled prior to removal from the CERCLA site and placed at an offsite facility without proper manifesting, the Criminal Investigation Divisions of EPA and Ecology monitored all site investigation activities conducted at the offsite facility.
