Soil Remediation
Remediation (the action of reversing or stopping environmental damage) and health risk assessment are increasingly required by both industry and property developers as more is understood about risks from contaminated land, and regulations become more stringent. Remediation of an industrial site may be required when an environmental permit is surrendered, or following an accidental release ...

In-Situ Remediation of Heavy Metals Using Sulfur-Based Treatment Technologies
The Metal Problem Highly toxic and highly soluble metals are contained in numerous waste streams including those from power, chemical, electronics facilities, general manufacturing plants, and mining facilities. Lead, chromium, arsenic, zinc, cadmium, copper, and mercury are the most common metal contaminants found on remediation project sites (US EPA, October, 2000). Cyanide is a common ...

Urban and Soil Remediation
Urban and Soil Remediation (the action of reversing or stopping environmental damage) and health risk assessment are increasingly required by both industry and property developers as more is understood about risks from contaminated land, and regulations become more stringent. Remediation of an industrial site may be required when an environmental permit is surrendered or following an accidental ...

Case Study: Basford Gasworks Remediation Project, Nottingham
The soils washing installation now owned and operated by HBR was formerly used by Kinatex Heijmans Joint Venture to process contaminated soil at the Basford Gasworks site. The project was the first major land based application of soils washing technology in the UK with in excess of 150,000 tonnes of soil successfully processed. Treatability Phase In the autumn of 1996, LHJV were contracted by ...

Application of passive sampling for measuring dissolved concentrations of organic contaminants in the water column at 3 marine superfund sites
Currently, there is an effort under way to encourage remedial project managers at contaminated sites to use passive sampling to collect freely dissolved concentrations (Cfree) of hydrophobic organic contaminants to improve site assessments. The objective of the present study was to evaluate the use of passive sampling for measuring water column Cfree for several hydrophobic organic ...

Remediation of Free Product with Horizontal Bioremediation Systems - Case Study
Project Location: Northern New York Client: Private Corporation – Petroleum Distribution Center Contamination: Gasoline Site Size: 10+ Acres Project Description: Seeking to excavate a trench to install an underground pipe, the client’s contractor severed a buried, and greatly mislocated, 10-inch gasoline header. The header was under significant head pressure, being fed by a ...

Lower costs, fewer delays - a highway expansion project applies XRF technology to obtain cost-effective remediation.
X-ray fluorescence (XRF) spectrometry is a non-destructive, analytical method used primarily to detect the metal composition in soil/solids samples. Portable XRF instruments can provide rapid, accurate analysis of heavy metal levels in soil on new construction or redevelopment sites. In response to the growing need for field analysis of metals, many of these units have been adapted for use in the ...
