Description:

Metals contamination of subsurface soils and ground water from a variety of industrial sources and uses has increasingly been discovered over the past decade. trategies are needed to efficiently and accurately characterize these types of sites to determine if soil remediation is possible and/or practical. hromium is one of Several metal contaminants often found at hazardous waste sites (DOE 1992; Sims 1986; U.S. EPA 1989). t has many industrial and manufacturing uses in the United States and other countries. ome of these include the manufacture of pigments, printing inks, photographic film, corrosion inhibitors, fungicides, ferrous and nonferrous alloys, and the leather tanning and electroplating industries. ard chrome plating, in particular, has been used extensively to manufacture components for both commercial and military aircraft. ue to the frequent occurrence of chrome plating sites and attendant environmental pollution, research was initiated to study this generic type of metal site. ooperative project between the U.S. Coast Guard and the Robert S. Kerr Environmental Research Laboratory, U.S. Environmental Protection Agency, was initiated in 1990 to evaluate various methods of site characterization at metals-contaminated waste sites. n particular, the uses of field-portable X-ray fluorescence (XRF) technology to determine total metals contamination in soils was evaluated.
