People who are obtaining uncontaminated soil from another entity can also prove that the soil is uncontaminated by having a licensed Professional Engineer test samples from the soil and verify that it meets Illinois EPA standards for uncontaminated soil with a pH between 6.25 and 9.0. To receive this certification, all testing on samples must demonstrate that the soil in question does not exceed maximum allowable concentrations of certain volatile organic compounds or other contaminants. If the location is either commercial or industrial, the Professional Engineer must also sign the certification in order for it to be valid. Construction or industrial site owners and managers do not need to obtain both certifications, but they must be able to demonstrate full compliance for one or the other.
Proving you have uncontaminated soil for your operation requires careful testing and certification. Contact us today to request information and verification for LPC-662 or LPC-663 certification.
