  • In the early 1970s, the United States government identified and became wary of hazardous materials in soil, surface water, groundwater, and building structures. Most of these contaminants resulted from the evolution of technology without the benefit of chemical regulatory controls. The cost for cleanup of such sites was projected to exceed a trillion dollars, the burden of which was to be borne by the taxpayer and responsible parties. The term “responsible party” is a broad term but, in the final analysis, a responsible party is usually a property owner....

  • With continued military downsizing and base closures, cleanup of unexploded ordnance (UXO) at former weapons ranges has become one of the most costly environmental problems the military faces. This study examines cost estimation for UXO remediation conducted at closed military installations, the difficulties of

  • In gravity injection, small volumes of reagents are gravity-fed into injection well(s) over a longer application period. The distribution and dissipation of the reagents in the saturated zone is largely controlled by the site hydrogeologic conditions. The gravity injection approach may reduce some of risks associated with chemical oxidation technologies. Additionally, given its prolonged application period, the oxidants may be able to penetrate into more of the lower permeability soils to address contaminants in these areas.

  • Exposure to pollutants from the World Trade Center attacks has come primarily in three phases. First, the collapse of the two 110-story towers and adjacent structures generated high-intensity, peak pollution discharges on September 11th . Second, fires from the crash of two fuel-filled airliners into the Trade Center towers and fires and the resulting smoke plume at Ground Zero following the towers’ collapse created significant additional pollution discharges, which continued to some degree for at least three months.

  • This material is available as an emulsifiable concentrate. Treatments are most often used for fly control. Occasionally, dichlorvos is applied to control ectoparasites during cleanup routines following the sale of an infested breeder or layer flock. It is applied as either a space spray (0.001 pound of active ingredient per 1,000 cubic feet) or as a premise spray (0.01 pound of active ingredient per 1,000 square feet of surface area). Dichlorvos is occasionally used as a spot larvicide treatment for fly control at a rate of 0.002 to 0.

  • The Department of Energy's Office of Environmental Management (DOE-EM) is responsible for cleaning up radioactive waste and environmental contamination resulting from five decades of nuclear weapons production and testing. A major focus of this program involves the retrieval, processing, and immobilization of waste into stable, solid waste forms for disposal. This report, which was requested by DOE-EM, examines requirements for waste form technology and performance in the cleanup program.

  • As a result of enforcement actions and settlements for noncompliance with federal pollution control requirements, the U.S. Environmental Protection Agency (EPA) reported that, for FY2011, regulated entities committed to invest an estimated $19.0 billion for judicially mandated pollution controls and cleanup, and for implementing mutually agreed upon (supplemental) environmentally beneficial projects. EPA estimates that these efforts achieved commitments to reduce, treat, or eliminate 1.8 billion pounds of pollutants in the environment, primarily from air and water.
