Abstract |
The report documents the feasibility study prepared for the waterways/shoreline portion of the Commencement Bay Nearshore/Tideflats Superfund site in Tacoma, Washington. The purpose of the feasibility study was to develop and evaluate the most appropriate remedial strategies for correcting the documented biological, human health and environmental impacts associated with contaminated sediments in the site. Given the large study area, the multiplicity of contaminant sources, and the diversity of ongoing activities within the site, the development of the recommended remedial strategies differ in many respects from the reports and implementation strategies at more traditional Superfund sites. Volume 2 contains the following appendices: evaluation of sediment recovery, details of dredging and capping technologies, specifications of major ARARs and TCBs, methods for estimating costs of sediment remedial alternatives, source loading data, sampling station locations, field survey data report - May 1986. |
