Conceptual Modelling of Pit Lake Processes and Ecological Risk

Conceptual Modelling of Pit Lake Processes and Ecological Risk

Clint McCullough (MiWER), Mark Lund (MiWER) Conceptual modelling to better understand ecological risks posed by pit lakes To ensure greatest scientific robustness of conceptual models we held a site visit and workshop in Collie with an expert panel of scientific researchers and managers from universities and State regulatory staff to best understand how these processes are likely working in different pit lakes. This workshop identified conceptual model needs e.g., a carbon cycling model and an acidity budget model. The intent is to then present the conceptual models as diagrammatic representations highlighting the nature of relationships between parameters and processes. These models will also…

Biological remediation of acid mine waters in a sewage evaporation pond

Biological remediation of acid mine waters in a sewage evaporation pond

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…
