Citation:
FORD, R. WORKSHOP ON MONITORED NATURAL ATTENUATION OF INORGANIC CONTAMINANTS IN GROUND WATER. Presented at EPA/ORD Workshop on Monitored Natural Attenuation of Inorganic Contaminants in Ground Water, EPA Region I Lab, North Chelmsford, MA, September 10, 2007.
Impact/Purpose:
To inform the public.
Description:
The Office of Research and Development (ORD) has developed a one-day seminar to present an overview of site characterization approaches to support evaluation of the potential for Monitored Natural Attenuation (MNA) as a remedy for inorganic contaminants in ground water. These seminars will be derived from information presented in a series of forthcoming ORD Technical Resource documents that have been developed in cooperation with the Office of Superfund Remediation and Technology Innovation and the Office of Indoor Air and Radiation. Monitored Natural Attenuation for inorganic contaminants is dependent on naturally occurring processes in the subsurface that act without human intervention to reduce the mass, toxicity, mobility, volume or concentration of contaminants. This seminar will provide an overview of technical issues that need to be addressed as part of the site characterization effort to support selection of MNA as a remedy for ground-water cleanup. The presentations are organized to address the following topical areas: (1) Regulatory and Conceptual Background - OSWER Directive 9200.4-17P, (2) Description of the Tiered Approach to Site Characterization, (3) Attenuation Processes and Use of Models, (4) Characterizing Attenuation, (5) Discussion of Specific Contaminant(s), (6) SiteSpecific Case Study, and (7) Synopsis. The workshop is intended for Federal, State, and Tribal regulatory personnel located within EPA Region 1. The agenda is structured to allow time for question and answer periods throughout the seminar.
