The MBS® stabilizer powder used in LEAD OUT® Paint Stripper was verified in the EPA's Superfund Innovative Technology Evaluation Program in the 1990's. Here is an exert from the EPA's report on MBS®: From the EPA “Superfund” Report

“Solucorp® developed a patent-pending system to reduce the leachability of heavy metals in soils, slags, and other solid wastes. Metal compounds are rapidly converted to less-soluble metallic sulfides. MBS® utilizes proprietary chemicals to treat the soil; soils can be excavated and treated in a pug-mill or in situ using soil mixing augers. The technology was demonstrated at the Midvale Slag Site in Midvale, Utah. Three waste streams, contaminated with arsenic (As), cadmium (Cd), and lead (Pb), were treated; approximately 500 tons of each waste was treated. A second test of 500 tons of one waste was conducted by Solucorp using EPA's protocol and oversight contractor. Toxicity Characterization Leaching Procedure (TCLP) leachable [lead] Pb concentrations were reduced to below the regulatory limit.” 

From our own tests and our customers’ verification tests

FYI: We recommend testing the paint waste by TCLP to document non-hazardous lead levels. Some of these tests were done using other methods and we are supplying these descriptions for information purposes only. (See our TCLP results : Reduced 23 mg/l and 36 mg/l down to 3.5 mg/l – below federal lead limit of 5.0 mg/l of lead).

  1. LEAD-OUT® Paint Stripper was used to successfully remove and remediate lead based paint in Big Sur and the Point Sur Lighthouse in California. The paint was tested by EPA SW846 test protocols, and the lab results showed 12% lead content by weight in the paint. The same lab using the same testing protocol tested the paint removed with LEAD-OUT®, and the results showed a reduction of lead content from 12% to 0.4% by weight. The paint waste was easily contained, and it was disposed of as non-hazardous waste.

  2. LM Installation out of Bainbridge, Georgia successfully removed and remediated lead based paint off a 2 million gallon fuel tank using LEAD-OUT® Paint Stripper. The lead based paint originally tested over 6800 parts per million (mg/kg) of hazardous lead. After LEAD-OUT® was used to remove the lead paint, it tested at approximately 95 parts per million. EPA regulations define lead based paint as paint containing at least 5000 parts per million of lead or 0.5% by weight.

  3. Untreated, flaking lead-based paint residues were mechanically removed from the metal structure of a derelict boat lift. These were tested by TCLP and found to leach in excess of 400 mg/l lead. LEAD-OUT® was used to strip this paint. The stripped residues were collected and submitted for TCLP testing, and leachable lead levels were found to be non-detectable, i.e., less than 0.010 mg/l.
