AbstractGroundwater samples were collected from the Peenya Industrial area of Bengaluru, India to test its quality, elemental composition and inherent bacterial population. Further analysis was done using GIS Based Geostatistical techniques to study the level of groundwater and to generate various maps of lineament, digital elevation, geomorphology, soil erosion, salt affected areas and water logging in this region. Physical and chemical parameters such as Total Dissolved Solids, pH, temperature, BOD, COD, metal ions present in the water samples were studied along with predominant microbial constituents. The Total Dissolved Solids and Total Hardness were far beyond the maximum concentration levels. Further analysis of the isolated bacteria was done using staining methods and biochemical tests. The results obtained showed that the area under study had wells ranging from shallow to deep heights of 30 to 80 meters, with a wide variety of 10-400 LPM; whereas the lineament map suggested that the area was bound with parallel ridges and joints. The geographical data represented pediplain complexes, anthropogenic terrains and water bodies. The area was found to go through a seasonal water logging and the soil loss was due to sheet erosion and rill erosion. It was also observed that the groundwater was contaminated with heavy metals such as lead, chromium etc. along with a diversified bacterial population.

The present work is aimed at assessing the water quality index (WQI) for the groundwater of Tumkur taluk. This has been determined by collecting groundwater samples and subjecting the samples to a comprehensive physicochemical analysis. For calculating the WQI, the following 12 parameters have been considered: pH, total hardness, calcium, magnesium, bicarbonate, chloride, nitrate, sulphate, total dissolved solids, iron, manganese and fluorides. The WQI for these samples ranges from 89.21 to 660.56. The high value of WQI has been found to be mainly from the higher values of iron, nitrate, total dissolved solids, hardness, fluorides, bicarbonate and manganese in the groundwater. The results of analyses have been used to suggest models for predicting water quality. The analysis reveals that the groundwater of the area needs some degree of treatment before consumption, and it also needs to be protected from the perils of contamination

Geothermal water resources are a kind of clean energy, which is a renewable resource to a certain extent and has a high value of development and utilization. To understand the hydrochemical characteristics, origins, and temporal variations of geothermal water quality in Tangtou, 13 geothermal water samples from 2007 to 2019 and geothermal geological conditions were collected. Cl− and Na+ are the major ions, which make the geothermal water belong Cl-Na type. The total dissolved solids values of geothermal waters were 1560–2512 mg/L and pH were in the range of 6.7–8.8. The development of faulted structures provides conditions for the formation of geothermal water. In addition, geothermal water is recharged by shallow underground cold water. Water-rock interaction, as well as mixing processes, in the process of long runoff path and the slower deep-water cycle is the main factor controlling the chemical composition of geothermal water. Calculated saturation index values indicated that the geothermal water was saturated with respect to silicate and carbonate minerals. Cation and silica chemical geothermometers indicated that reservoir temperatures ranged from 94.63 to 196.10 °C and from 69.13 to 123.75 °C, respectively. Based on the grey relational analysis, the main physicochemical components of geothermal water are obviously correlated with the geothermal water exploitation and precipitation. Overall, affected by exploitation and precipitation, main physicochemical components (such as the total dissolved solids, total hardness, temperature, Na+, Ca2+, Cl−, K+, and Mg2+) showed a certain stage.

The present work illustrates the potential application of techniques of spatial analysis via geographic information systems (GIS) to categorize the distribution of temporal and spatial of water prediction characteristics to determine the water quality parameters of the Shatt Al-Arab River (SAA), southern Iraq. Eight main water quality parameters and three heavy metals were measured from December 2018 to October 2019. The total dissolved solids, chloride, sulfate, and total hardness were compared with previous data that were measured from 2014 to 2018 based on data availability. The geochemical characteristics were also investigated to analyze water quality parameters. The study was performed by selecting eleven stations according to the nature areas of SAA. Water samples were acquired from the eleven stations for four seasons (winter of 2018 through autumn of 2019). Results revealed that total dissolved solids ranged between 950 to 8500 mg/L, total hardness varied from 400 to 2394 mg/L as calcium carbonate (CaCO3), the sulfate ranged from 149 to 1602 mg/L, and chloride ranged from 330 to 3687 mg/L. The results showed that SAA had high salinity with a low hazard of sodicity. The SAA waters mainly fall below the Dolomite-Magnesite tie-lines which indicated the dissolution of carbonate rocks. This research also found that the study area confined from Al-Maqal station to Abu Flus port station where the salty marine water coming from the Arabian Gulf remains for longer periods. The SAA is not suitable for drinking and irrigation water according to Iraqi and World Health Organization (WHO) standards. This study suggested building a blocking dam downstream of the SAA to prevent salty water from coming back from Arabian Gulf.

In this present study, the geology, relief, spatial variation and challenges of groundwater quality has been carried out, using Kriging Model. The methodology employed was drawn from primary and secondary data sources. Detailed chemical analyses for some of the parameters of the groundwater were done on a total of twenty-one (21) samples of both hand-dug wells and borehole waters collected during the full field investigation. In the laboratory analysis, the AAS and XRF machines were used to analyze eight (8) samples, namely: Temperature, pH, Total Dissolved Solids (TDS), EC, Total Hardness, Lead, Iron, and manganese. The results of the chemical analyses which were akin to groundwater geochemical characterization based on the ranges of parameters shows that the value of pH in the study area ranges from (6.53 to 7.30), The Total Dissolved Solids ranges between (0.00 to 24.00), the EC has concentrations between (0.06 to 22.00) which was also around the permissible units of both SON and WHO. Total Hardness of the samples of the area run from lowest concentrations of (60 to 3915) which does not exceed the SON permissible unit, but exceed the recommended limit of WHO. The corresponding limited ranges of iron and manganese ranges from (0.53 to 15.24 and 0.4 to 3.35),the concentrations of Lead from lowest to highest were (0.74 to 2.31), both of which defy the recommended limits of WHO (0.05) and that of SON (0.01). Based on this, it was concluded that some of the groundwater sources assessed are safe for human consumption. If the practice of consuming groundwater without treatment continues, it may lead to health hazard.. ANOVA-F (One Way) was adopted in testing the hypothesis (Calculated F=6.63 while Critical F=2.16). The study recommended that appropriate measures should be taken to bring the higher concentrated parameters to desired levels.

Abstract The present work evaluated the groundwater quality index (GWQI) depending on some physicochemical analyses of thirteen groundwater samples in the Zubair district in Basra Province, Iraq. The collected groundwater samples were subjected to an extensive physicochemical analysis to evaluate the characteristics of water for drinking purpose according to Iraqi standard. For calculating the (GWQI), twelve water quality parameters were considered; turbidity, pH, chloride, total dissolved solids, total hardness (TH), electrical conductivity (EC), sodium, sulphate, phosphate, calcium, nitrate, and magnesium. The analysis of the results reveals that all the samples surpassed the portability of drinking water limits. High values of the (GWQI) in the obtained groundwater samples could possibly be caused by the higher values of electrical conductivity, total hardness, chloride, total dissolved solids and sodium within the groundwater. The calculated GWQI values ranged from 73.36 to 595.92. The pollution index (PI) was calculated for the study area with values ranged from 2.97 to 8.26. Correlation coefficients amongst the chosen water parameters exhibited some strong relationships. Finally, the analysis shows that the groundwater in this particular area needs to be treated before its consumption, and in addition, it usually needs to avoid the hazard of contamination. Principal component analysis (PCA) and cluster analysis (CA) indicate that the acquiring-data from groundwater samples are explained 90.5 % of the variance in the data with a four-component system that explains a large portion of the total variance of collected data.

The relation between physical and chemical indices of production and standard crops of plankton, bottom fauna and fish was examined in 100 British Columbia lakes. A significant increase in plankton and fish quantities with increase in total dissolved solid content of lake waters was demonstrated and a similar relationship suggested for bottom fauna. Although the general form of the relationship between mean depth and plankton, and between bottom fauna and fish quantity, suggested a hyperbolic curve with larger quantities in lakes of low mean depth, the only generalization which seemed justified was that quantities of fauna from lakes of great mean depth were never as high as those found in some lakes of low mean depth. No significant relation was found between intensity and length of growing season and quantities of plankton, bottom fauna or fish, although a significant relationship was demonstrated between summer epilimnion temperature and plankton.In a multiple regression analysis using all lakes the predominance of total dissolved solids over mean depth in affecting summed indices of lake fauna was shown. However for lakes in the southern interior plateau, one of the 9 regions distinguished in British Columbia, no significant relation could be demonstrated between mean depth or total dissolved solids and summed indices of fauna or plankton alone. Thus total dissolved solid content of the water appeared to be the most important factor in determining the general level of productivity in lakes studied throughout the province, although within a region neither total dissolved solids nor mean depth could be used either singly or together to predict plankton, bottom fauna or fish quantities.

A geochemical study of mine water in the Western Jharia coalfield area was undertaken to assess its quality and suitability for drinking and domestic purposes. To assess mine water quality of the study area, a systematic sampling was carried out during the monsoon season, 2013. Eighteen representatives mine water sample were collected from both underground (underground sump and surface water discharge) and opencast mines, and analyzed for pH, electrical conductivity (EC), total dissolved solids (TDS) , major cations (Ca2+, Mg2+, Na+ and K+) and major anions (HCO3- F-, Cl-, NO3-, SO42-). The pH of the analyzed mine waters ranged from 6.8 o 8.3 and electrical conductivity (EC) values ranged from 608 uS cm-1 to 1350 uS cm-1. TDS ranged from 432 to 1080 mg L-1 and the spatial differences in TDS reflect the geological formations, hydrological processes and prevailing mining conditions of the region. The anion and cation chemistry indicate the general ionic abundance as: HCO3-> SO42-> Cl-> NO3->F- and Mg2+>Ca2+> Na+> K+ in the mine water of the study area. The water quality assessment indicated that total dissolved solids (TDS), total hardness (TH), magnesium and sulphate are the major parameters of concern in the study area and make it unsuitable for drinking and domestic purposes.

Some interior areas of Sindh are poorly studied previously which are considered as main sites for present investigation. For the study of ignored amphibian fauna, we conducted a survey to observe the environmental condition of amphibian habitats. The physical characteristics of habitat such as types of vegetation and presence of predators were observed, while water samples were collected from all aquatic habitats for analysis of parameters i.e. pH, electric conductivity, total dissolved solids, total hardness, chloride, sulphate, phosphate, nitrite and nitrate as well as carbon dioxide. All the habitats were analyzed thoroughly and designated as highly contaminated and unfavorable especially for spawns and larvae and their conservation status was found entirely deteriorated, though abundance of vegetation was observed alongwith availability of potential predators.
