“…Due to its high salinity, water generated in CBM production must be disposed of via regulated injection wells or surface discharge. It can also be used for beneficial applications; however, its application is hindered by limited knowledge of water quality [313,325]. A composite geochemical database was recently generated by Dahm et al [325] to assess the geochemical signature of CBM produced water in four of the major CBM basins in the Rocky Mountain region of the United States.…”

“…Results reported that TDS, sodium adsorption ratio (SAR), temperature, iron, and fluoride are the parameters that most commonly exceed standards for drinking, livestock and irrigation water applications. Database water composition was dominated by sodium bicarbonate and sodium chloride type waters with TDS concentrations of 150 to 39,260 mg/L [325]. The U.S. Bureau of reclamation reports that within basins, the TDS of CBM water varies from 200 to 170,000 mg/L [326].…”

“…The U.S. Bureau of reclamation reports that within basins, the TDS of CBM water varies from 200 to 170,000 mg/L [326]. Based on the database it was suggested that prediction of water quality compositions for beneficial use applications in CBM-producing basins worldwide is going to be based on basin geology, hydrogeology, and methane generation pathways [325]. The unique quality of produced water from CBM/CBNG as well from the oil and gas industry provides opportunities for novel treatment technologies.…”

Membrane distillation is a process that utilizes differences in vapor pressure to permeate water through a macro-porous membrane and reject other non-volatile constituents present in the influent water. This review considers the fundamental heat and mass transfer processes in membrane distillation, recent advances in membrane technology, module configurations, and the applications and economics of membrane distillation, and identifies areas that may lead to technological improvements in membrane distillation as well as the application characteristics required for commercial deployment.

Produced water (PW) is a large‐volume waste product from the oil and gas industry. Converting this waste into a resource requires system models to optimize treatment designs, transportation, and storage costs. Five models are presented and evaluated for their capabilities. All the models fall within the AACEI Level 5 standard for preliminary evaluation uses, with cost accuracies of ±30%. Three databases that contain useful geospatial data that could improve model results are presented and described. The USGS PW database is the most comprehensive of the group. Most PW data, for both volume and chemistry, has problems with incompleteness, inaccuracies, and lack of correlation from state to state. Model improvements that are needed include the following: Application of correct desalination processes to varying ranges of salt content and different PW types. Use of appropriate organic removal technologies. Inclusion of up‐to‐date cost indices. Clear graphical results and flow diagrams; energy usage at each step, pumping parameters, energy recovery opportunities, and water and waste stream flows. Costs output for each step and for the whole system with improved accuracy. Indications of the output water quality. Ability to evaluate toxicity of trace constituents. Linkages with real data sets and GIS. Ongoing support/funding for maintenance and upgrades. Feedback loops to validate results with proven field data. Common computing platforms for model development and evolution.

Bicarbonate is often a major ionic constituent associated with produced waters from methane gas extraction and coal mining, yet few studies have determined its specific toxicity. Currently, the environmental risk of bicarbonate anion in water discharges is assessed based on the toxicity of sodium chloride or artificial seawater and is regulated via electrical conductivity. Increased NaHCO(3) added to Ceriodaphnia dubia in synthetic or natural water gave similar 48-h 10% effective concentration (EC10) values of 1750 ± 125 mg NaHCO(3)/L (mean ± standard error) and 1670 ± 180 mg NaHCO(3)/L, respectively. Bicarbonate was toxic to C. dubia in both waters with conductivities above 1900 µS/cm. In contrast, when conductivity was elevated with NaCl, toxicity to C. dubia was observed only above 2800 µS/cm. Bicarbonate also impaired C. dubia reproduction with an EC10 of 340 mg NaHCO(3)/L. Major ion composition also influenced Zn bioavailability, a common co-occurring metal contaminant in coal mine waters, with sublethal concentrations of NaHCO(3) and elevated pH increasing Zn toxicity. Higher pH was the dominant parameter determining a 10-fold increase in the 48-h 50% effective concentration (EC50) for Zn toxicity to C. dubia at pH 8.6 of 34 µg Zn/L (95% confidence limit = 32-37 µg Zn/L) compared with the Zn toxicity at approximately circumneutral pH. Exposure of the freshwater shrimp Paratya australiensis (Atyidae) in natural water to increasing bicarbonate gave a mean 10-d 10% lethal concentration (LC10) of 850 ± 115 mg NaHCO(3)/L, associated with a mean conductivity EC10 of 1145 µS/cm, which is considerably lower than toxicity of NaCl and artificial seawater to this species reported elsewhere. Because toxicity was influenced by salt composition, specific ions should be regulated rather than conductivity alone in mine wastewater discharges.
