  • The East-Sullivan Mine Site: from Abandonment to Restoration

    The East Sullivan mine was closed in 1966, leaving 15 Mt of acid-generating tailings free to contaminate the environment. An experimental wood waste cover was implemented in the early 80's in order to prevent sulphide oxidation. Contaminant production and dispersion were investigated in the 90's to validate that concept and guide later actions. Ligneous wastes stop oxygen, and also favour ...

  • Principles for Streamlining Environmental Restoration

    For example, published reports on the use of the “Principles” at DOE sites show savings of millions of dollars and avoidance of months or years of effort at sites in Nevada, Ohio, Kentucky, and South Carolina. At a site in South Carolina, ongoing challenges with implementing a cleanup program led to the regulators calling a “time out” in enforcing compliance agreement milestones and a rethinking ...


  • Transforming Ecosystems: When, Where, and How to Restore Contaminated Sites

    Chemical contamination has impaired ecosystems, reducing biodiversity and the provisioning of functions and services. This has spurred a movement to restore contaminated ecosystems and develop and implement national and international regulations that require it. Nevertheless, ecological restoration remains a young and rapidly growing discipline and its intersection with toxicology is even more ...

  • Restoration of Vegetation Affected By Diesel Spill

    The toxicity of diesel spill was reduced facilitating healthy growth of grass and other vegetation at the site. TPH of the soil was reduced from 65,000 ppm to less than 1000 ppm by on site application. Restoration of vegetation and reduction of toxicity of spill using AgroRemed was achieved at a cost of less than $ ...

  • A framework for establishing restoration goals for contaminated ecosystems

    As natural resources become increasingly limited, the value of restoring contaminated sites, both terrestrial and aquatic, becomes increasingly apparent. Traditionally, goals for remediation have been set prior to any consideration of goals for ecological restoration. The goals for remediation have focused on removing or limiting contamination while restoration goals have targeted the ultimate ...
