This project started after debris created from the demolition of the former Ithaca Gun Club was found to contain high levels of lead. Pre-construction activities consisted of constructing a decontamination pad, installing erosion control and installing an intricate dust suppression system to run continuously during site activities.
Utilizing a TerraBond chemical reagent and a hydraulic excavator OP-TECH mixed and stabilized approximately 600 tons of lead impacted debris to a TCLP level of less than 5 milligrams per liter (mg/l). Confirmatory samples were collected and a final report was prepared showing the reduction in lead concentration. Based on the results of the stabilization process, the previously hazardous debris was approved for disposal at a non-hazardous landfill. The 1,950 tons of non hazardous lead contaminated crushed masonry were then loaded, transported and disposed of.
