	LEADX® TEST - Philip Services SOIL REMEDIATION Heavy Metals Contamination in Soil LEADX® was blended with a contaminated soil sample to determine its effectiveness as a treatment for heavy metals. The soil sample contained a variety of heavy metals in the concentrations shown below. After blending with LEADX® the soil was analyzed using the Toxicity Characteristic Leaching Procedure (TCLP) and analyzed using EPA Method 6010. The LEADX® produced significant reductions in the levels of leachable heavy metals in the sample:   Heavy Metal Before LeadX (ppm) After LeadX (ppm) % Reduction EPA Limit (ppm) Lead 5.040 0.051 99% 5.000 Silver 0.647 <0.011* >98%* 5.000 Beryllium 0.551 0.039 93% Zinc 0.898 0.075 92% Mercury 0.577 0.046 92% 0.200 Cadmium 0.643 0.070 89% 1.000 Chromium 0.804 0.110 86% 5.000 Barium 8.950 2.300 74% 100.000 Nickel 0.812 0.290 64% Selenium 0.102 <0.066* >35%* 1.000 Arsenic 0.475 0.310 35% 5.000 * Below detectable levels. Laboratory tests of LEADX® were conducted by an independent laboratory, Philip Services Corporation of Houston, TX, on a certified soil sample provided by Environmental Resource Associates of Arvada, CO Conclusion: LEADX® significantly reduced levels of leachable heavy metals - Even when multiple heavy metals were present - Even when only trace amounts were present RC Global Marketing, Ltd. 542 County Road 211 Reagan, TX 76680 254-587-2445, e-mail leadx@leadx.org Web page www.leadx.org
