USA has successfully applied a wide range of treatment methods to soil contaminated with solvents, pesticides, heavy metals, petroleum compounds, and other priority pollutants. We can help you identify the best technology for each site based on your schedule and space constraints, nature and concentration of the contaminants present, cleanup standards, soil permeability, proximity to groundwater, and a variety other site-specific parameters. USA's role is to provide physical personnel and equipment to implement the required soil remediation program (excavation, material handling, mechanical piping, electrical, and site restoration services).
These methods include:

USA has experience with a variety of treatment methods and can help you determine the most cost effective solution for your client's environmental problems. For example, we are often asked to provide cost proposals for the on-site treatment (stabilization) of lead impacted soil. Our clients ask us to provide them with a proposal to treat the lead to below 5 ppm TCLP. If you are treating contaminated soil that is characteristically hazardous for lead, treatment must meet the Universal Treatment Standards (UTS) found in 40 CFR 268.48. For lead impacted soils, the treatment standard is 0.75 mg/L TCLP. In addition to meeting the UTS, you must also identify any Underlying Hazardous Constituents (UHC) that may apply (arsenic, cadmium, chromium, etc). These UHC's can be identified by applying either generator process knowledge or analytical testing. If any UHC's are identified, they must also meet the UTS for those constituents.

Should treatment not meet the UTS, the material must be disposed of as a hazardous waste. If the material is less than ten times the UTS, it may be possible to dispose of the material at a permitted Subtitle C landfill (hazardous) with no further treatment required (direct burial). Notifications to the Texas Commission on Environmental Quality may be required dependent upon the method of treatment, types of contaminants, and where the treatment is occurring. Please consult 30 TAC 335.2 for any permitting or notification requirements.
