“…The plot of Ca 2+ + Mg 2+ vs. HCO 3 − + SO 4 2− also confirmed that the presence of HCO 3 − and SO 4 2− (63.89% of samples) was associated with the soil system that majorly affects the nature of groundwater in the study area (Figure 7c). This was supported by plotting HCO 3 − vs. Cl − + SO 4 2− graph, indicating that 61.1% of the samples (Figure 7d) fell below the equiline; this also confirmed that weathering and the influence of anthropogenic activities are the primary source of excess concentrations of ions in groundwater [59]. In particular, an excess amount of HCO 3 − in the groundwater indicates that physical weathering of Na + and K + silicates along with anthropogenic activities of organic waste decomposition are significant sources of groundwater contamination in the study region.…”

The quality of groundwater plays an important role in human health, and it majorly influences the agricultural process in the southern part of India. The present study mainly focused on evaluating the quality of groundwater used for domestic purpose in semi-arid regions of the southern part of India. The samples were collected in 36 locations, covering the entire investigation zone. The collected samples were analyzed for various physical and chemical characteristics of groundwater and compared with the world health organization standards. The entropy-weighted water quality index (EWQI) of the groundwater revealed that 16.67% of the samples required primary-level treatment before they could be used for drinking purposes. About 72.23% of the samples were in the good-to-medium category for drinking purposes, as was identified through weighted overlay analysis. The ionic relationship plot was used to identify the source of contamination and it revealed that carbonate weathering and anthropogenic activities are the primary sources of groundwater contamination. The present results show the contaminated zones and offer more helpful solutions to strengthen the water management policy in the study region.

“…This can be challenging and cost-prohibitive. Re-use for irrigation purposes is theoretically appealing; however, prolonged application of CBM-produced waters can result in salt alkalization and salinization of agricultural soils, and these effects are exacerbated by significant transpiration and/or water stagnation due to poor drainage (Mallants et al 2017;Wang et al 2018). Other disposal mechanisms are expensive-costing as high as US$ 0.3 per m 3 (where corresponding value of gas is of the order $ 10 2 -10 3 ) (Boysen et al 2002).…”

Management of coalbed methane (CBM)-produced water is a crucial part of the water-energy nexus, especially as CBM is projected to play a key role as a bridge fuel in major economies. In this paper, we consider one management technique, i.e., desalination of CBM-produced water to generate potable water. We discuss a confluence of geographic, sociotechnical, regulatory, and other circumstances that could make this concept viable for select coal-bearing regions. Having said that, for maximizing benefits, it is prudent to take a synergistic view targeting multiple objectives (water access, health, environmental impacts, and ease of waste management). Thus, we make design recommendations and suggest a system-evaluation framework for making sustainable decisions related to produced-to-potable water systems. For instance, a key question is whether such systems should be centralized or decentralized-and this paper highlights crucial tradeoffs that are present in both the cases.

“…Moreover, where groundwater is available, obtaining shallow groundwater is more economical and convenient than deep groundwater [13][14][15]. However, the shallow groundwater has direct recharging and discharging relationships with local precipitation and surface water and is greatly affected by anthropogenic activities due to shallow buried conditions and rapid circulation [16][17][18]. Therefore, the quality and safety of shallow groundwater have drawn global attention.…”

Understanding factors influencing groundwater quality is critical to the development of best management practices at the large watershed scale. In this study, the shallow groundwater (10–20 m depth) in the Su-Xi-Chang region, eastern China, was investigated as part of a monitoring program from 2007 to 2008 to analyze the regional groundwater quality as well as the hydrogeochemical processes and their controlling factors. Conventional physicochemical water parameters (pH, turbidity, electrical conductivity, dissolved oxygen, total phosphorus), major cations (Na+, Ca2+, Mg2+ and NH4+) and anions (Cl−, NO3− and SO42−) were measured. Hydrochemical methods and multivariate statistical methods were applied to analyze the hydrogeochemical signatures, origins, the similarities among the variables and to identify the main pollution sources in the groundwater. The results showed that (1) the concentrations of TDS (224.89–1086.70 mg/L) and turbidity (0.1–18.60 NTU) were higher than the class II groundwater quality standards in China and the WHO drinking water standards, (2) there were extremely high concentrations of ammonia (0.01–32.90 mg/L), with a mean value of 0.72 mg/L and (3) the nitrate concentrations (average value of 22.07 mg/L) exceeded the class III groundwater quality standards. The study also provided evidence that weathering, dissolution of carbonate, halite and silicate and cation exchange were the possible primary hydrogeochemical control mechanisms in the groundwater. The sources of ammonia, total phosphorus, sulfates and nitrates included rock–water interactions and anthropogenic activities. The groundwater administration of pollution sinks and sources, long-term legal frameworks and economic incentives should be improved to optimize watershed scale management in the context of rapid development in China.
