Jan 01, 1995 · article{osti_56469, title = {Bescorp soil washing system for lead battery site treatment. Appliions analysis report. Project report}, author = {Gaire, R J}, abstractNote = {The Brice Environmental Services Corporation (BESCORP) Soil Washing System (BSWS) and its applicability in remediating leadcontaminated soil at lead battery sites was evaluated.
In soil washing, the most important factor affecting removal of Pb was pH, with greater removals observed at a lower pH. Ethylenediaminetetraacetic acid (EDTA) addition significantly improved soilwashing performance at pH 3, and the temperature and liquidtosolid (L/S) ratio had a minimal effect for the range of conditions studied.
Mar 07, 2022 · Guidance for Groundwater Cleanups. EPA's corrective action goal for groundwater is to prevent adverse effects to human health and the environment, both now and in the future. EPA believes that shortterm exposure prevention and longterm cleanup goals are both essential elements to achieve this overall goal. With respect to shortterm ...
(c) (2) If an employee is exposed to lead for more than 8 hours in any work day the employees' allowable exposure, as a time weighted average (TWA) for that day, shall be reduced according to the following formula: Allowable employee exposure (in µg/m 3) = 400 divided by hours worked in the day.
Oct 01, 1995 · The efficiencies of six washing solutions in removing lead from the contaminated soils were then investigated via batch washing experiments. Unlike conventional fieldscale soil washing, all particle size fractions were washed and recovered in these benchscale experiments. HCl and EDTA obtained the best Pbremoval efficiencies.
Lead can be present in outdoor and indoor air. Lead in outdoor air comes mainly from industrial sources (, smelters, waste incinerators, utilities, and leadacid battery manufacturers). Windblown soil and road dust also may contain naturally occurring lead as well as lead from industrial sources, deteriorated paint, and the combustion of ...
Steps taken during the last two decades have reduced exposures to lead in tap water. These steps include actions taken under requirements of the 1986 and 1996 amendments to the Safe Drinking Water Act and the Environmental Protection Agency's (EPA's) Lead and Copper Rule. Even so, lead in water can come from homes with lead service lines that connect the .
A typical decision tree for soil remediation is shown in Figure 1. The relative costs are shown in Figure 2. Each address a contaminate or group of contaminates and may designed to be effecting in a variety geological settings and geochemistries. The product links provide a more detailed review of how each may be used.
A novel chemical extraction/washing process is described for detoxifying lead contaminated materials, and in particular, for detoxifying broken lead/acid storage battery casings made from ebonite. In particular, the preferred process of the invention enables the lead content of broken ebonite battery casing material to be reduced to the point that the processed ebonite is no .

Oct 01, 2013 · Transfer of Pb and As into vegetables grown on orchard soils historically contaminated by Pb arsenate pesticides was measured in the greenhouse. Lettuce, carrots, green beans, and tomatoes were grown on soils containing a range of total Pb (–915 mg/kg) and As (–211 mg/kg) concentrations. The vegetables were aciddigested and analyzed for total Pb .
Feb 26, 2014 · A study published online last month in the Journal of Environmental Quality looked at lead contamination at an urban community garden in Kansas City, MO. The study measured lead concentrations in the soil before planting and at harvest. The researchers then checked lead concentrations in the edible portions of vegetable samples after harvest.
Oct 01, 2008 · AA was investigated for its applicability for the removal of lead, cadmium and nickel from soil. Batch soil washing experiments were performed on g portions of the spiked soil using different ...
