The Soil Substrate Or Dirted Planted Tank a How to Guide B 20 Soil Washing Study Conclusion United States Army
May 20 32 The Soil Substrate Or Dirted Planted Tank a How to Guide Discussion in Substrate started by Tim Harrison Jul 31 In a low energy tank a filter that turns over about 5 times the tanks total volume per hour will suffice However having said that I tend to stick to the general rule of turnover for a planted tank that is 10 times the 527 Reduction of Toxicity Mobility and Volume Soil washing reduces the toxicity mobility and volume of contaminated soil at the site With the removal of contaminants from the site the overall toxicity and volume of particulate lead will be reduced 528 Cost It is estimated that soil washing will cost $140 per ton

Lead in Residential Soils Sources Testing and Reducing AUDIT REPORT mvsusacearmymil
Lead occurs naturally in soils typically at concentrations that range from 10 to 50 mg/kg milligrams of lead per kilogram of soil equivalent to parts of lead per million parts of soil or ppm Because of the widespread use of leaded paint before the mid s and leaded gasoline before the mid testing a soil washing process designed to chemically extract uranium from contaminated soils Based on the test results the Department expected that soil washing would reduce the volume of soil requiring disposal by 95 percent generate minimal amounts of radioactive wastewater and reduce cleanup costs by about $40 million
