SulfaTreat begins as a safe and stable compound, and when it reacts with H2S, it forms another safe and stable compound, iron pyrite, also known as “fools gold.” Reacted SulfaTreat product has passed every applicable environmental test and EPA regulation including: California’s Title 22 Metals Analysis; Calwet Extraction Test; Fish and Shrimp Bioassay Test For Toxicity; and the EPA’s Toxic Characteristic Leaching Procedure (TCLP). Reacted SulfaTreat has many non-disposal recycle uses: road material, brick manufacturing, and agriculture. A major California university has tested the spent material and found it to be beneficial to plant growth without changes in pH or other detrimental effects to the soil. A CAVALCO OMG representative will assist you in determining the best option for the recycling/disposal of your spent SulfaTreat material.
