Chase completed the purchase of US Ecology’s Oak Ridge, Tennessee based low-level radioactive waste (“LLRW”) and mixed waste (“MLLW”) brokerage assets and customer records, effective December 20, 2001. This purchase deepens Chase’s commitment to the radioactive waste management market and expands our existing brokerage and field services capabilities to service the eastern United States.

Chase completed a $2.3M PCB cleanup at a remote wildlife refuge in the Hawaiian Islands. Since the refuge was on a remote island with no services, Chase had to mobilize a complete inventory of tools, materials, equipment, waste packages, and spare parts sufficient to handle expected and unexpected circumstances. This project entailed strict standards for wildlife protection, while working within a timetable that did not allow for scheduling delays. The project included excavation of soils and debris, waste characterization, waste packaging, site inventory, and final waste transportation off the island for disposal. In spite of the project scope increasing to over double originally envisioned by the client, Chase completed the project within the mandated schedule with zero biological take.

Chase was contracted to remove elemental mercury from drain traps from numerous laboratories at a state university. Chase inspected, cleaned, and monitored over 600 drains in less than one week. Chase personnel worked closely with university personnel to ensure that routine classroom activities and vital experiments were not disrupted during the cleaning. In addition to removing the elemental mercury, Chase removed drums of small debris, glassware, sharps, and other material from the drains. The project involved detailed performance monitoring and pre- and post-project monitoring of university effluents. Post-project monitoring revealed that mercury levels had dropped dramatically to below acceptable levels.

Chase Environmental Group (Chase) was contracted to perform an environmental assessment of residual impacts to soil and stream water quality at an operating whiskey distillery after collapse of an 800,000-gallon warehouse destroyed by fire. Twenty Geoprobe borings were installed within the footprint of the former warehouse. Soil samples were screened for evidence of potential impact from a release of bourbon. Selected samples were analyzed for ethyl alcohol and total organic carbon (TOC). Stream water samples that receive run-off from the burn area were also analyzed for ethyl alcohol and TOC. Chase helped negotiate a cost-effective remediation program that included revegetation of the burn area, and quarterly sampling and reporting of the results.
