Recent developments in lead based cleanup criteria at hazardous waste sites
- Lawler, Matusky, & Skelly Engineers, Pearl River, NY (United States)
This paper briefly compares the requirements and application of two guidance documents issued by the US Environmental Protection Agency (US EPA) to address soil lead contamination. The Office of Solid Waste & Emergency Response (OSWER) Revised Interim Soil Lead Guidance recommends a risk-based screening level for lead in soil for residential use and the use of the Integrated Exposure Uptake Biokinetics Model to evaluate potential risks to humans from environmental exposure to lead at hazardous waste sites in residential settings. The Office of Prevention, Pesticides, and Toxic Substances (OPPTS) issued guidelines to reduce lead-based paint hazards, including lead contaminated soils in residential areas. Both of these guidance documents identify 400 ppm as the level in soil below which no further action is necessary. However, the OPPTS guidance identifies concentrations between 400-5000 ppm as the levels in soil which necessitate only interim controls. In the past, the final record of decision issued by the US EPA for most Superfund sites, where the primary contaminant of concern was lead, used the OSWER guidance to determine the final lead cleanup level for the site. In many cases the RODs issued by EPA required the removal of lead contaminated soils that contained levels of lead between 400-5000 ppm. Even though the OPPTS guidance is applicable to residential areas where soils have been contaminanted with lead as a result of LBP, if applied to hazardous waste sites many remedial actions required by EPA in the past would not be necessary under this guidance.
