The paper presents the results of the physicochemical parameters of the springs of Andros which were studied to evaluate the chemistry of the major ions and solute acquisition processes, which control the chemical composition and the suitability of the quality of water for drinking use. Forty two samples were taken for physicochemical analysis almost at the end of the summer period, in September 2014. The Piper plot was used for the hydrogeochemical classification of groundwater which also indicated that the majority of groundwater samples belong to the Ca-Na-HCO3-Cl type. According to the Durov plot the majority of samples, can be positioned in field 2 in which a process of cation exchange is in progress. Also, the HCO3 /(HCO3 +SO4) ratio indicates a weathering process from carbonic acid. In general, the majority of samples can be characterized as potable.

AbstractThe aim of this study is to evaluate the hydrogeochemical characteristics and water environmental quality of shallow groundwater in the Suxian mining area of Huaibei coalfield, China. The natural formation process of shallow groundwater in Suxian is explored using Piper trilinear charts and Gibbs diagrams, and by examining the ratios between the major ions. United States Salinity Laboratory (USSL) charts, Wilcox diagrams, and the water quality index (WQI) are further employed to quantify the differences in water quality. The results reveal that the main hydrochemical facies of groundwater are HCO3–Ca, and that silicate dissolution is the main factor controlling the ion content in shallow groundwater. The USSL charts and Wilcox diagrams show that most of the water samples would be acceptable for use in irrigation systems. The WQI results for each water sample are compared and analyzed, and the quality of groundwater samples around collapse ponds is found to be relatively poor.

This study is part of the more general framework for diagnosis of the quality of water resources in the Biskra area and its suitability for irrigation. This work reports the results of an analysis of physicochemical groundwater quality. Groundwater samples were collected from 12 boreholes in different aquifers exploited in the area, and used for drinking and domestic purposes. The results showed that the water of the limestone aquifer (Maastrichtian) is better than other aquifers (phreatic, Miopliocene, Lower Eocene). This affects more particularly the pH, conductivity (mineralization), total hardness, and concentration of the major elements. As far as the same aquifers (phreatic, Miopliocene, Lower Eocene), present water which classified mediocre highly mineralized for irrigation because EC > 2250 μS/cm (class 4). The Maastrichtian aquifer presents a poor water quality (class 3), according to the Riverside classification.

The modelling of water quality is an integrated source of good management, which benefits the environment and its people. In the present study, the quality of water was measured in terms of physicochemical analysis and WQI. This analysis facilitates the eco-management study of the water. In this article, we have measured the quality of the water in Taladanda canal and river Mahanadi nearby Paradip area in terms of WQI for the year 2017. Five different sampling stations were selected from Taladanda canal and nine sampling points were selected from river Mahanadi. It was found that the water quality index in most of the areas was much higher, however, the water is of poor quality. But in PPL site areas, the quality of water was found to be very poor and not suitable for human use. The pollution load was found to be much higher in the Taladanda canal and moderate in Mahanadi River near the Paradip area.

A study was carried out to determine the groundwater quality in parts of Perumal Lake, Kurinjipadi Taluk, Cuddalore district, Tamilnadu. Totally, 12 groundwater samples were collected at different parts of study area and 16 water samples from surface reservoirs (Perumal lake) and analyzed for physicochemical parameters (pH, EC, TDS, TH, Na, K, Ca, Mg and Cl, SO4 , HCO3- , NO3 ) in order to understand the hydro geochemistry of the water. The results of analysis were interpreted with geology and geomorphology of the area and also by various geochemical diagrams such as Piper trilinear plot and USSL classification diagram. Suitability of this water for its utility was verified using Indian standards. The result indicates irrespective of the seasons that only one well is suitable for drinking purpose, with remaining suitable for domestic and irrigation purpose. Further, from the results, it is pointed out that most of the well water falls in Na-Cl type indicating the influence of seawater in these wells which was confirmed by Piper plot. According to SAR (alkali hazard) and specific conductance (Salinity hazard) is plotted in USSL diagram, classification of water for irrigation purpose can be determined. Majority of groundwater samples fall in C3S1 zone indicating high salinity and low sodium hazard, satisfactory for plants having moderate salt tolerance on soils. In surface water most of the samples fall in C2S1 indicates medium salinity and low sodium hazard.

Abstract. The quality of drinking water is dependent of its source(s) and means of collection. The water available for drinking in the study area is accessible through groundwater exploration. This research was carried out to determine the quality of water from the selected boreholes within the university and checked by the World Health Organization (WHO) drinking water standards for the various parameters considered. Samples were gotten from seven (7) of the sited boreholes and various physico-chemical parameter tests such as turbidity test, conductivity test, pH test, copper test, manganese test, chloride test, sulphate test, chromium test, nitrate test and cadmium test and bacteriological tests as total plate count, total coliform count and faecal coliform count were carried out following due procedure, precautions and the results analyzed. The results show that most samples were satisfactory for the tests carried out while only two (samples from Behind Admin and Engineering) were unsatisfactory in turbidity while one sample (sample from Back of College 2) was unsatisfactory in the cadmium test. WQI showed that the water samples had excellent qualities except for that from Back of College 2 which had poor quality and is unsuitable consumption.

Quality of water in the subsidence area related to coal mining is important for water usage in the coal mining areas. In this study, forty-two samples from the subsidence pools in the Luling coal mine, northern Anhui Province, China have been collected and measured for their major ion concentrations, and the data have been applied for quality evaluating of drinking and irrigation purposes. The results suggest that the water samples from different pools have different concentrations of major ions and all of them can be classified to be Na-HCO3 type. According to the results of water quality index, all of them are suitable for drinking (considering only about the major ion concentrations). However, sodium absorption ratio (SAR) and residual sodium carbonate (RSC) give different answers about irrigation purpose, the water can be used for irrigation according to SAR whereas cannot be used according to RSC, and can be attributed to the high concentrations of CO32− and HCO3−. Gibbs diagrams and relationships between Na+ normalized Ca2+, Mg2+ and HCO3− suggest that different extents of contributions from weathering of silicate, dissolution of carbonates and evaporates are the main mechanism controlling the major ion concentrations of water from the subsidence areas in this study, which is related to the natural conditions of the pools.
