Test Programs Large Stockpiles Nutrient Testing Compost Amendment Goals$ Observe the behavior of parameters in large stockpiles with no treatment Assess impacts of adding nitrogen, heat retention & anoxic conditions Accelerate reduction of PAH and PHC concentrations by adding to compost Length$ 2 years 1 year 6 months Lab$Results$$Table$ 1$&$2$SC$ Reduction PAHs EC, boron, SAR were just above Table 2 SCS in one or more samples Variable results for PHCs N was being used to support bacterial growth Thinner stockpile – most promising results Reduction in PAH Samples met CCME & Ontario stds for metals Consulting with MOE re acceptable limits for PAHs and PHCs
