superfund site

The Office of Superfund Remediation and Technology Innovation (OSRTI) is hosting an informative webcast presentation by Jane Bare, expert on Life Cycle Impact Assessment (LCIA) in EPA's Office of Research and Development.

Ms. Bare's presentation will provide an overview of LCIA, including general scope, terminology and existing models, and will provide examples of how LCIA has been applied, including an application to a Superfund site.

The North Fork of Clear Creek (NFCC), Colorado is an acid-mine-drainage-impacted stream typical of many mountain surface waters affected by historic metal mining in the western United States.

The stream is devoid of fish primarily because of high metal concentrations in the water (e.g., copper and zinc) and has large amounts of settled iron oxhydroxide solids that coat the streambed.

Sustainability has numerous definitions and is often discussed. However, there are fewer lessons derived from its application.

The concept for its application evolved out of a study to determine whether brownfields could be redeveloped to be more environmentally friendly.

The course of this research led us to realize that it might be possible to intentionally plan projects to achieve prescribed qualities related to environmental, social, and economic systems.

The U.S. Environmental Protection Agency (EPA) is planning to treat mining influenced water (MIW) from the National Tunnel Adit that discharges to North Clear Creek near the City of Blackhawk, Colorado.

North Clear Creek is part of the Clear Creek/Central City Superfund Site, and the National Tunnel is a major contributor of contaminants to this tributary.

The EPA would like to determine the trade-offs between two modes sulfate reducing bioreactor (SRBR). One is an ethanol-fed SRBR and the other is a solid substrate fed SRBR.

Ethanol fed and solid substrate-fed SRBR were operated in parallel.
