“…Many methods such as multivariate statistical techniques (e.g., cluster analysis, principal component analysis, and factor analysis) [13,14], hydro-geochemical evaluation [15,16], heavy metal indices (e.g., heavy metal pollution index, degree of contamination, heavy metal evaluation index, contamination factor, and health risk assessment) [17][18][19], and water evaluation indices [13] have been developed for assessing water quality considering physicochemical parameters. Grading water quality indicators largely depends on indicator concentration and the rate of relative toxicity.…”

Groundwater is a major source of drinking and agricultural water supply in arid and semiarid regions. Poor groundwater quality can be a threat to human health especially when it is combined with hazardous pollutants like heavy metals. In this study, an innovative method involving entropy weighted groundwater quality index for both physicochemical and heavy metal content was used for a semiarid region. The entropy weighted index was used to assess the groundwater’s suitability for drinking and irrigation purposes. Thus, groundwater from 19 sampling sites was used for analyses of physicochemical properties (electrical conductivity—EC, pH, K+, Ca2+, Na+, SO42−, Cl−, HCO3−, TDS, NO3−, F−, biochemical oxygen demand—BOD, dissolved oxygen—DO, and chemical oxygen demand—COD) and heavy metal content (As, Ca, Sb, Se, Zn, Cu, Ba, Mn, and Cr). To evaluate the overall pollution status in the region, heavy metal indices such as the modified heavy metal pollution index (m-HPI), heavy metal evaluation index (HEI), Nemerow index (NeI), and ecological risks of heavy metals (ERI) were calculated and compared. The results showed that Cd concentration plays a significant role in negatively affecting the groundwater quality. Thus, three wells were classified as poor water quality and not acceptable for drinking water supply. The maximum concentration of heavy metals such as Cd, Se, and Sb was higher than permissible limits by the World Health Organization (WHO) standards. However, all wells except one were suitable for agricultural purposes. The advantage of the innovative entropy weighted groundwater quality index for both physicochemical and heavy metal content, is that it permits objectivity when selecting the weights and reduces the error that may be caused by subjectivity. Thus, the new index can be used by groundwater managers and policymakers to better decide the water’s suitability for consumption.

“…Chen et al (2016) [23] simulated the groundwater contamination in Tainan City, Taiwan, and the study revealed that the total mass of pollutants in the aquifer increased by 72% after 10 years. [24] studied the groundwater quality of Turfy Swamps in the Changbai Mountain area below the highway as the related pollutant, and showed a great influence on the groundwater quality of these wetlands with increasing highway operation time. Paradis et al (2016) [25] investigated groundwater nitrate concentration using a number of different groundwater flow and mass transport simulations to evaluate the potential impact of climate change and agricultural adaptation scenarios on Prince Edward Island, Canada.…”

Evaluating water quality indicators is a crucial issue in integrated water resource management, since potable water is an essential resource for the world's health and sustainable development. The current study was developed using a coupled model of MODFLOW and MT3DMS (Mass Transport 3-Dimension Multi-Species) to integrate two water supply systems, surface water (polluted drains and canals) and ground water, to identify the contamination process of the groundwater from drains as fresh water is polluted and the contamination level exceeds the standard limits. The study was applied to two cases: the first was a hypothetical simulation and the second was the real case of the Nile Delta Aquifer (NDA). Four different scenarios were simulated to first identify groundwater contamination by total dissolved solids (TDS), and then select the more efficient protection process. The first scenario involved changing polluted drain and canal boundary conditions regarding head and concentration; the second consisted of studying the location of the polluted drain in a low permeability layer or a confined aquifer; the third was based on installing a cut-off wall in the polluted drain sides; and the fourth investigated the use of lining materials for polluted drains. The results reveal that aquifer contamination was decreased by increasing the water head of canals by 50 cm and decreasing the drain head by 50 cm and concentration by 25%, whereby large quantities of groundwater were protected. The percentages of salt repulsion in the hypothetical case were +10.66, +12.89, and +24.99%, while in NDA they were +6.29, +8.71, and +25% respectively compared with the base case. Decreasing the aquifer hydraulic conductivity led to decrease in aquifer contamination, in which the confined aquifer pollution was less than the unconfined aquifers due to the clay cap, which plays a significant role in minimizing the solute transport into the groundwater reservoir, and to reduction of the aquifer salt variation by +19.01% for the hypothetical case. The results indicate that the cut-off wall is effective for contamination management in shallow aquifers (hypothetical case) and the reduction in aquifer salt was +28.49%, whereas it had no effect in the deep aquifer (NDA), where the salt was reduced by just +0.34%. Using the drain lining scenario prevented contamination from the polluted drains and protected the freshwater in the aquifer, so that the aquifer salt mass reductions were +91.02 and +70.13% for the hypothetical case and NDA respectively, indicating that this method is more effective for controlling groundwater contamination. Polluted drains should be located in a low permeability layer to minimize the water degradation. This study represents a new contribution to groundwater protection techniques by changing the boundary conditions, installing a cut-off wall and using linings for polluted drains, and shows the way forward for the future treatment of polluted stream networks.

“…The quality control was kept in all metal analyses as stated by individual instruction manuals and method precision and more than 95% in confidence interval (CI) with the correlation coefficient, r=~1 of respective calibration curves. Each method was recalibrated after running ten (10) samples and all quantitative analyses were executed in triplicate to ensure precision. Chemical and spectrometry analyses were carried out in the own laboratory of IES and Central Science Lab, University of Rajshahi, Bangladesh.…”

Bangladesh is a densely populated and developing country that faced severe water contamination, crisis, and security. About 100% of the population has access to the availability of freshwater, but the purity of water is always concerned. The groundwater of Bangladesh is under increasing threat from overexploitation, population growth, rapid urbanization, and pollution from industries, domestic and agricultural sources. For the assessment of heavy and toxic metal contamination in shallow groundwater, the study collected 40 water samples from different stations in the middle-west part of Bangladesh. The results showed that three metals ion, viz. iron, manganese, and lead exceeded the concentration limit of WHO (2011) in most of the water samples indicating severe human health hazard. The single-factor pollution index (I i ) and compound pollution index (CPI) value of these three (3) metals were very high, i.e., much greater than 1. The other metal concentrations were found within the safe permissible ranges. The values of heavy metal pollution indices, viz. heavy metal pollution index (HMPI), heavy metal evaluation index (HMEI), degree of contamination (Cd ), Nemerow Index (NeI), and ecological risk measurement (ERI) showed that most of the water samples were found medium to high levels of contamination in the study area. The analysis results revealed that an average of 32.6%, 15.6%, and 51.8% of the water samples was found low, medium, and high risk from heavy metal, respectively. There were 20 samples found highly contaminated with heavy metals out of 40 samples. The study results revealed that both the geogenic and anthropologic activities influenced the groundwater system of the area. It suggested that the groundwater quality should go under a continuous monitoring process for sustainable water quality management in the area. The study findings could help with further planning of potential future remediation measures for policymakers.
