Formatted Abstract/Summary
Coal seam gas (CSG) is becoming a major energy source in Australia. Coal seam gas water (CSGW) is a byproduct that is pumped out of coal seams in order to release CSG. CSGW is generally considered water of poor quality (containing brine and petrochemicals) and thus the management and potential further usage of CSGW has been subject of concern. CSGW has a number of potential uses such as irrigation, coal washing for coal mining, cooling in power stations etc. Treated water has been discharged into local rivers or re-injected into underground aquifers. However, no comprehensive hazard assessment has attempted to study the quality and quantity of organic micropollutants in CSGW. Conventional chemical monitoring programs have been criticised that they do not account for the combined effects of mixtures of chemicals, in the case of CSGW this is a particular problem where the identity of organic micropollutants is often unknown and in addition to organics there is a suite of inorganic pollutants and heavy metals. Bioanalytical tools have been used in a wide range of water sources from sewage to recycled water to complement chemical analysis for cost-efficient risk assessment. Here, we are reporting for the first time the application of bioanalytical assessment of three CSGW samples taken from private wells and are pristine, untreated bore waters in proximity to commercial CSG wells. Baseline toxicity levels were comparable to the range of secondary treated effluent and clearly higher than surface waters. Induction of arylhydrocarbon receptor was observed in one sample where polyaromatic hydrocarbons were also detected in chemical analysis. Slight estrogenicity was detected but the level was comparable to other groundwater samples, and other endocrine endpoints were below the detection limits. No genotoxicity was detected and the oxidative stress response was very low. Outcome of the project will improve the understanding of CSGW toxicity in order to enhance risk assessment and better inform water management decisions.
