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
