Presentation Description Frequently Asked Questions Regarding Management of Chlorinated Solvents in Soil and Groundwater
Recently the Dept. of Defense’s ESTCP Program published a Frequently Asked Questions (FAQs) document regarding chlorinated solvent site management. The FAQ document addresses 25 key questions that provide a concise overview of current knowledge and emerging concepts regarding management of subsurface chlorinated solvent releases. Example questions include:
What is a chlorinated solvent “source zone”?
Why do we keep finding new challenges?
Why are contaminants in low permeability zones important?
What have we learned in the last half-century?
What can we expect from common source treatment technologies?
What are the effects of source treatment on cleanup time frames?
How does one compare treatment versus containment?
How can we set cleanup objectives that are attainable and beneficial?
The authors of the FAQ document, Tom Sale, Chuck Newell, Hans Stroo, Rob Hinchee, and Paul Johnson brought a rich variety of theoretical, practical, and regulatory perspectives to select and provide short answers to each of the 25 FAQs. The document is intended to help state regulators, federal regulators, consultants, Dept. of Defense staff and community members make better site management decisions. ESTCP hopes the document contributes to better use of resources, more effective remediation and risk management, and more productive cooperation between the parties involved in site cleanups.
