Quantitative analysis of remedial approaches, costs, and time required to remediate dry cleaner sites

Abstract

This article presents an analysis of remedial approaches, costs, and time required to remediate dry cleaner sites in the United States based on data compiled by the State Coalition for the Remediation of Dry Cleaners (SCRD). Trends in soil and groundwater remedy selection are identified and discussed. Median costs and the time required to remediate dry cleaner sites are presented.In addition, median costs and the duration of soil and groundwater remediation for the most widely used remedial approaches are reported. The analysis is intended to serve the needs of stakeholders, including responsible parties, consultants, regulators, and litigants, as well as real estate developers, banks, and other holders of portfolios of impacted dry cleaner sites by providing quantitative results useful for planning and transactional analysis.

Chemical or Natural? Including LCA in Social CBA to Compare Remediation Alternatives for a Dry-Cleaning Facility

“…There are several soil remediation techniques available to address sites contaminated with VCHCs, e.g., soil vapor extraction, excavation, biological remediation, chemical oxidization and multiphase extraction [8]. When the groundwater is also contaminated some additional techniques can be used, namely pump and treat, air sparging and monitored natural attenuation [8]. Even with all these remediation techniques, remediating sites contaminated with VCHCs often proves to be a complex process.…”

“…In Flanders (Belgium), for example, the cost of remediating a site contaminated with VCHCs ranges from 60,000 euro to more than 2 million euro (based on 23 remediation projects in the period 1999-2009, [9]). In the United States of America, the median cost to remediate a dry-cleaning contamination is 235,000 dollars with exceptional cases exceeding a cost of 1 million dollars (based on 128 remediation projects in the period 1997-2006, [8]).…”
