Phase 2 Remediation Services at the PR-58 site in North Kingstown, Rhode Island

The U.S. Army Corps of Engineers, New England District is seeking sources for Phase 2 remediation services at the PR-58 site in North Kingstown, Rhode Island. The objective of this remediation is to remediate the dissolved phase plume and render the site and vicinity suitable for unlimited use and unrestricted exposure in the long term. The selected source area remedy is in-situ dechlorination bioremediation, which will be addressed with a combination of in-situ reductive dechlorination (ISCR), enhanced in-situ biodegradation (EISB), and Monitored Natural Attenuation (MNA). • The PR-58 site was previously used by the U.S. Navy and U.S. Army, resulting in releases of hazardous materials and impacts to environmental media. • The highest concentrations of chlorinated volatile organic compounds (CVOCs) are present in the soil, groundwater, and bedrock fractures. • The site has been split into two phases for remedial action, with Phase 1 being the source area and Phase 2 being the dissolved phase groundwater plume. • The full-scale remediation area of the plume spans approximately 44 acres and encompasses a range of geological conditions and contamination concentrations. • Interested firms should submit a capabilities package, including business classification, documentation of relevant project experience, and project teaming.
