This practise is being driven by corporate sustainability goals, munity and societal pressures to demonstrate improved water stewardship, as well as climate and regulatory pressures. However, water reuse often results in water quality promise which can then result in decreased recovery through problems in processing circuits, product quality, and an increased likelihood of discharge of water that cannot meet environmental regulatory requirements. On most mine sites, there is usually a disjuncture between water quantity management and water quality management with the latter being managed solely as an environmental problem. It is being increasingly clear that water quality and quantity must be managed as an integrated system. In order to integrate water quality and quantity management to achieve multiple objectives the dynamics of water and constituents must be understood. Using examples from a study being conducted at a coal mine the Bowen Basin, this paper will outline the dynamics of water and salts on the site. Introduction The need for sustainable water management practises is being driven by corporate sustainability goals, increased public scrutiny of water use, management, and environmental stewardship, the relative economics of increasing reuse against the alternative of increased supply of fresh water and climate conditions. The ability to simultaneously meet water quantity, water quality and product quality objectives is being an increasingly challenging ponent of water management on mine sites. However, because the water system on a mine site acts as a plex system with feedbacks and interactions between the natural climate driven system and the engineered reticulation there are often unintended impacts from water management decisions that only consider one set of objectives In the coal industry, there has been considerable investment in improving water management on sites. This has been driven by widespread and prolonged drought as well as corporate targets for freshwater savings. Over the last decade most sites have adopted water reuse as a means for making freshwater savings. However, water reuse results in increased salinity in site water stores (Moran et al, 2021). The increase in salinity is driven largely by evaporation and ongoing salt inputs from spoil, coal and groundwater. Effective management of dissolved salts can provide opportunities for reducing risks and costs in managing water and the environment, processing efficiency, product quality and operating/maintenance. In order to manage both water quality and quantity in an integrated system to meet multiple objectives on coal mines requires an understanding of the nature and sources of salts。 the dynamics of the salt fluxes on a site。 and the impact of water quality on production and product quality. These factors must also be balanced against the risk of nonpliant discharge. The aim of this work was to increase understanding of the mine and climate conditions that result in salt fluxes from various parts of the site into the mine water reticulation system. With this information, operational guidelines can be developed that allow sites to proactively, rather than reactively manage the water system to meet multiple objectives. This pap
