Clint McCullough (MiWER), Mark Lund (MiWER), Joel May (Xstrata Coal Pty Ltd) Is a mining operations sewage evaporation pond able to biologically remediate acid pit dewatering water? Workshop Evaporation Pond 2 (WEP2) is a water body used to reduce low pH and/or high salinity surface water volumes through evaporation. Approximately 4 ML of acid dewatering water from WEP2 was introduced into the 60 ML Workshop Evaporation Pond 1 (WEP1) in late May 2003. WEP1 is a hyper-eutrophic water body into which raw sewage and CCP workshop vehicle washdown and waste waters are continuously fed. In situ sulfate reduction processes produced alkalinity and removed heavy…
