Use of Monte Carlo Simulation for Human Exposure Assessment at a Superfund Site
Risk Analysis, 1994This work presents a comparison of probabilistic and deterministic health risk estimates based on data from an industrial site in the northeastern United States. The risk assessment considered exposures to volatile solvents by drinking water ingestion and showering.

On the assessment of health risks at superfund sites using Monte Carlo simulations
Journal of Environmental Science and Health . Part A: Environmental Science and Engineering and Toxicology, 1997Abstract In this paper, state‐of‐the‐art risk assessment models, and the most current and applicable site specific exposure data are employed in the reassessment of baseline risks at three Superfand Sites for which a Record of Decision has been issued since 1990.

Use of Tire Chips in the Final Cover System of a Superfund Site Landfill
GeoCongress 2008, 2008The final cover system of a Superfund Site landfill in Illinois was designed to include a tire chips gas-collection layer and a tire chips drainage layer. A design-phase performance demonstration was prepared in support of the use of the tire chips layers.

Reducing costs by using value engineering on superfund projects
Remediation Journal, 1990AbstractThis article informs the remediation community about value technology and how the technologies of remediation and value engineering (VE) have been successfully combined. The article describes to the practitioner how the first value engineering study on Superfund work was initiated by the Corps of Engineers for EPA.

Using toxicity data to evaluate ecological effects at Superfund sites
Journal of Hazardous Materials, 1993Abstract Toxicity data (used here to mean toxicity tests or bioassays) have been employed in two ways at Superfund sites. In a retrospective manner, bioassays have served as direct measurement endpoints (e.g., bioassays of contaminated sediment) and, in a predictive manner, bioassay data from the literature have been used to interpret other ...

Review of ecological-based risk management approaches used at five Army Superfund sites
Integrated Environmental Assessment and Management, 2012Abstract Factors used in environmental remedial decision making concerning ecological risk are not well understood or necessarily consistent. Recent Records of Decision (RODs) for Army CERCLA sites were reviewed to select case studies where remedial management occurred in response to ecological risks. Thirty-four Army RODs were evaluated

Trichloroethylene (TCE) is a widespread environmental pollutant common in groundwater plumes associated with industrial manufacturing areas. We had previously isolated and characterized a natural bacterial endophyte, Enterobacter sp. strain PDN3, of poplar trees, that rapidly metabolizes TCE, releasing chloride ion.

Basing Superfund Cleanups on Future Land Uses: Promising Remedy or Dubious Nostrum? [PDF]
, 1997 Abstract: Supporters of the effort to link cleanups at hazardous waste sites to the sites' expected land uses claim that amending language in the federal Superfund statute to allow this may yield a number of benefits. These include rationalizing the cleanup process and decreasing cleanup costs, promoting economic development in the local communities ...

TECHNOLOGY STRATEGY IN A REGULATION‐DRIVEN MARKET: LESSONS FROM THE US SUPERFUND PROGRAM
Business Strategy and the Environment, 1996Estimates by the US Office of Technology Assessment of the costs to clean up the 1246 EPA National Priority List sites stand at more than $500 billion over the next 50 years. This cost estimate is based on existing technologies which are neither as technically advanced nor economically efficient as is necessary to realistically complete the job ...

Environmental Monitoring and Assessment, 2019
The Pine River downstream of the Velsicol Superfund site has been contaminated with various hydrophobic organic pollutants for more than 50 years. Remediation and sediment dredging near the site began in spring of 1999, and was completed in 2006. In 2011, the Michigan Department of Environmental Quality completed a baseline assessment report long-term ...
