20. 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

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

22. ! Database$Framework:$$Start$using$as$a$planning$
