Project Description

  • Assessment and Remediation of former disposal pit contaminated with petroleum, metals, Lead Arsenate, and DDT pesticide mixing area at former apple orchard.
  • Disposal pit soils to be excavated had high levels of lead, which were stabilized on-site to avoid classifying the excavate as hazardous materials saving $100,000+ in disposal fees.
  • Disposal pit area was part of residential subdivision and final conditions were required to meet unrestricted residential use criteria.
  • Pesticide mixing area had extremely high levels of pesticides requiring all remediation work to be conducted in Level C personal protective equipment.
  • Approximately 150 tons of soil was excavated from the pesticide mixing area and, due to high pesticide concentrations, was transported to Quebec, Canada for disposal.
