TREATING ACIDITY IN COAL PIT LAKES USING SEWAGE AND ...

Treating acidity in pit lakes using sewage and greenwaste
(i.e., day 37). Although treatments containing sewage were very variable between replicates,
both treatments containing sewage appeared to decline in solute concentrations greater than
did green waste alone.
