MINING CAN IMPACT WATER QUALITY IN MANY WAYS. For a start, mines often operate in remote areas where supplies are often very localised. For instance, surface and groundwater resources that…

Mine closure plans (MCPs) detail the post mining land use (PMLU) of landforms constructed during mining that are left at closure and how they are intended to perform. Completion criteria…
Defining a post mining land use (PMLU) is fundamental to developing an over-arching vision to pit lake closure planning. However, multiple PMLUs can present issues to all closure planning, including…
Pit lakes often present poor water quality as a key hazard Pit lakes are characterised by their frequent poor water quality, due to elevated concentrations of contaminants of potential concern…
Understanding pit lake water quality is critical to operational management and especially closure planning. Why do we need to know pit lake water quality? Pit lake water quality defines…
Mesocosm studies were used for studying whole aquatic biotic communities for site-specific magnesium guideline values as per ANZG (2018) Water Quality Guidelines. Magnesium (Mg) is a mining‐related contaminant in the...

LIABILITIES OR OPPORTUNITIES? Pit lakes can represent significant liabilities at mine closure. However, depending upon certain characteristics of which water quality is key, pit lakes often also present opportunities to...

Every mine closure plan should contain a clear description of what the next land use will be. Pit lakes present a significant departure from the terrestrial land that was there...

Toxicity testing is primarily used for determining acceptable chemical concentrations in receiving systems. Testing occurs at a variety of scales, with benefits and contraindications for each scale. However, single-species tests...
