In response to a growing societal mandate, land disposal of hazardous wastes is gradually being replaced by treatment technologies. This shift to “alternative technologies” is the result of the impacts of past land disposd practices on other environmental media (groundwater, surface water, and air). A prime motivation for pdopting alternatives to land disposal is to eliminate these cross-media ...

The Regional Ground Water Forum is a group of ground-water technical specialists, representing EPA's Regional Offices, organized to exchange up-to-date information related to groundwater remediation at hazardous waste sites. Proper site characterization has been identified by the EPA Regional Ground Water Forum as a major issue of concern for decision-makers at many hazardous waste sites. In or...

Hazardous waste management involves the collection, transportation, treatment and disposal of hazardous wastes. In this paper a new multiobjective location-routing model is proposed. Our model also includes some constraints, which were observed in the literature but were not incorporated into previous models. The aim of the proposed model is to answer the following questions: where to open trea...

In the recent past, household hazardous waste has become an issue to more and more communities. In an effort to control the pollution generated within a household, various methods have been set forth in col­ lecting and disposing of these wastes. Unfortunately, all too often the hazardous waste collection days are poorly attended, and the costs become prohibitive when measured against the amoun...

In this study, ferrochromium slag (FS) and electric-arc furnace dust (EAFD) samples were examined for their hazardous hexavalent chromium content mainly by X-ray photoelectron spectroscopy (XPS) analysis. According to the experimental results, magnesium-silicate constitutes main framework of both FS EAFD samples. Highly crystalline contains 3.11%Cr2O3 as spinel phases while constituent is much ...

In 1989, 30 states levied taxes on the generation or management of hazardous waste. These taxes constitute one of the broadest applications of an emissions tax in U.S. environmental policy and provide a natural experiment for studying the effects of such taxes. This paper examines the impacts on chlorinated solvent waste from metal cleaning, using plant-level data from EPA's 1987-89 Toxic Relea...
