The Regional Superfund Ground Water Forum is a group of EPA professionals, representing EPA's Regional Superfund Offices, committed to the identification and the resolution of ground water issues impacting the remediation of Superfund sites. The Forum is supported by and advises the Superfund Technical Support Project. Remediation of trichloroethylenecontaminated soils and ground waters is an i...

The application of a field portable X-ray fluorescence spectrometer (FPXRF) to measure Cu, Zn, and Pb in soil and sediments at recreational boatyards by Lake Mälaren in Sweden was investigated. Confirmatory chemical analysis on freeze-dried samples shows that, ex situ, the FPXRF produces definitive level data for Cu and Zn and quantitative screening data for Pb, according to USEPA criteria for ...

The U.S. Environmental Protection Agency (EPA) has been working toward the establishment of treatment standards for contaminated soils. The Office of Emergency and Remedial Response is in the process of developing and carrying out a plan to address the data needs for establishing the Pest Demonstrated Available Technologies (BDAT) for Superfund soils. The BDAT program is divided into phases. Ph...

A global concerns focus on environmental protection and natural resource management. The sustainability of natural resources has taken central stage amongst researchers, the public and policy makers as a key issue in global change and biodiversity preservation. Need has risen to develop an understanding of microbial diversity responsible for variable reaction in different soil orders. There is ...

Types of land disposed residuals from selected metal smelting and refining industries are described, as are the origin and disposition of land disposed residuals from the primary copper industry as an example. Quantities of land-disposed or stored residuals, including slags, sludges, and dusts, are given per unit of metal production for most primary and secondary metal smelting and refining ind...

The sustainable management of forest resources can only be achieved through a well-organized road network designed with the optimal spatial planning and the minimum environmental impacts. This paper describes the spatial layout mapping for the optimal forest road network and the environmental impacts evaluation that are caused to the natural environment based on the multicriteria evaluation (MC...

A system of preventive protection of houses against radon penetration from the ground [1] has been in operation for more than 15 years in the Czech Republic. The determination of a so-called radon index of the building site represents the first step. The assessment is based on measurements of soil gas radon concentration and on the determination of soil permeability. During the years, the metho...

National governments are becoming increasingly aware of the importance of their soil resources and are shaping strategies accordingly. Implicit in any such strategy is that degradation threats and their potential effect on important soil properties and functions are defined and understood. In this paper, we aimed to review the principal degradation threats on important soil properties in the UK...

An integral component in the development of media-specific values for the ecological risk assessment of chemicals is the derivation of safe levels of exposure for wildlife. Although the derivation and subsequent application of these values can be used for screening purposes, there is a need to identify the threshold for effects when making remedial decisions during site-specific assessments. Me...
