On the basis of groundwater chemistry, an evaluation of groundwater for domestic and irrigation purposes  was carried out for different regions of Bangladesh. Using the chemical compositions and different quality parameters, irrigation quality was assed using 6 different techniques: USDA method, FAO guidelines, Water-Types approach, Combined approach proposed by Al-Bassam et al. (2003), Ali (2010), and GOB (2007) guidelines. Drinking quality was judged by WHO (2011) provisional guidelines and GOB guidelines. Concentrations of major cations and anions of most groundwater samples were within allowable limit. Except one location (i.e. Barisal), the water for irrigation purpose are suitable to 19 marginally suitable considering salinity and sodicity. For drinking purpose, all except 2 locations (i.e. 20 Sunamgonj and Barisal, where iron is a concern) are found suitable. At these locations, other aquifer layer 21 with low Fe can be searched for safer Fe level. Alternatively, Fe removal system can be assembled for 22 collecting drinking water.Keywords: Groundwater, Hydrochemistry, Quality parameters, Integrated quality assessment, Bangladesh

AbstractThe study examines the water quality of Shahdadkot, Qubo Saeed Khan and Sijawal Junejo talukas of Qambar Shahdadkot District, less affected by industrial contamination. A total of 38 groundwater samples were collected and analysed for 28 parameters. The results indicated that 57.89% samples were not suitable for drinking purpose with total dissolved solids above than maximum permissible limit of World Health Organization (WHO) (1000 mg/L). The pH, total phosphate, orthophosphate and nitrite were within WHO limits. The concentration of essential metals more than half samples, fluoride in 60.52% and heavy metals 0–50% were contaminated higher than permissible limits of WHO. The statistical analysis of water quality parameters was also carried out to evaluate coefficient of determination among the parameters, cluster analysis and principal component analysis. Water quality determined for irrigation based on Kelly index (KI), sodium percentage (Na%), chloride–sulphate ratio, sodium adsorption ratio, permeability index (PI), chloroalkaline indices 1 (CAI-1), residual sodium carbonate and chloride bicarbonate ratio indicated that samples (55 to 100%) could be used for irrigation purposes. The consumption of water with high concentration of salts and fluoride above the permissible limits may be a cause of a number of diseases in the area.

The aims of the current research are to assess the drinking water quality of the groundwater in the Gadilam River Basin, which is located in the northern part of Tamil Nadu, by identifying the groundwater quality index and examine its suitability for drinking. The current work determines the levels of groundwater quality parameters based on 120 groundwater samples; 50 samples from Archaean formation, 34 samples from Quaternary formation, 35 samples from Tertiary formation and the remaining sample from Cretaceous formation. Additionally, this research compares the determined levels with the various standards for drinking. Furthermore, the variability of parameters of the groundwater quality is explored in this paper by using the spatial interpolation method. The conclusion of this research reveals that the groundwater quality parameters such as Calcium (Ca2+), Magnesium (Mg2+), Nitrate (NO32-), Fluoride (F-), Sulphate (SO42-), Bi-carbonate (HCO3-) and Percentage of Hydrogen (pH) values are observed to be within the limiting value for WHO 2017 in all the formations during the seasons in which they were taken. The water quality index (WQI) values of the Archaean, Quaternary and Tertiary formations are found to be less than 100 meq/L in all stations in both seasons. In order of WQI, these stations come under the category of “Excellent” and “Good”. The Piper trilinear classification of groundwater samples fall in the field of mixed Ca-Mg-Cl, and No dominance, some of the samples represent Na-K, Cl types of water.

The quality of selected bored well and dug well waters from the central tracts of the Lalitpur region in the state of Uttar Pradesh, India, was investigated for irrigation purposes.  The study area is situated within the latitudes 24° 35' N and 24° 43' N, and the longitudes 78° 20' 41" E and 78° 30' E in the basin of the Shahzad River, which is a tributary of the Betwa River. Granites and gneisses of Archaean age are exposed in various parts of the area. The selected groundwater samples were analysed for major cations, anions, trace elements, pH, electrical conductivity (EC), sodium absorption ratio (SAR), residual sodium carbonate (RSC), permeability index (Pl), and sodium per cent (SP). The analysed data were plotted on Wilcox and U.S. salinity diagrams to evaluate chemical quality of groundwater for irrigation. The SAR values (ranging from 0.47 to 79) are within the permissible limits. A majority of samples (i.e., 57.5%) belong to C3-S, class whereas remaining samples (42.5%) fall in C2-S1 class. Plots of SP against EC indicate that a large number of samples (67.5%) fall within Excellent to Good type of water whereas remaining samples lie within Good to Permissible type. Hence the water can be used for all types of crop on soils of medium to high permeability.

In this study, the hydrogeological characterization of the northern sector of the Lauria Mounts carbonate hydrostructure (southern Apennines, Basilicata region) has been carried out and the hydrochemical properties of different collected groundwater samples have been characterized. Several normal springs drain the hydrostructure, some of them characterized by high annual mean discharges. Groundwater samples were collected from different springs; many parameters such as pH, electrical conductivity, and total dissolved solids have been measured, and major (cations and anions) elements and stable isotopes have been analysed following standard test procedures. Other chemical characteristics were derived from the analysed quality parameters. The results elucidate that the main hydrogeochemical processes control the chemical content and assess the quality of the groundwater within the hydrostructure. The analyses highlight that the chemical compositions of groundwater are strongly influenced by the lithology, especially limestones and dolomitic limestones; they explain and confirm the hydrogeological setting of the system. The groundwater system displays light different geochemical signatures. The processes contributing to the concentrations of major ions depend primarily on carbonate dissolution. The analysis, in all studied groundwater samples, shows that the facies groundwater type is Ca–HCO3, bicarbonate is the dominant anion, and calcium is the dominant cation with appreciable magnesium concentrations. To identify the aquifer’s recharge areas, the environmental stable isotopes oxygen and hydrogen, deuterium, and 18O were analysed. The unaltered δ18O and δD signatures for the groundwater of the major springs allows identifying the recharge area of these emergencies at elevations ranging from 900 m to 1000 m (a.s.l.), pointing out the presence of deeper flow regime feeding of these springs. The groundwater sample isotopic characteristics of D and 18O suggest that most of the groundwater is recharged directly by infiltration in a high-permeability medium.

Groundwater from nine wells of three different districts, located at Sana’a  secretariat was analyzed for hydrochemical quality assessment. Measurements of water quality parameters including pH, EC, CO32-, HCO3-,Cl-,NO3-,SO4 2-,Ca2+, Mg2+, Fe3+, K+, and Na+ were carried out . Classification of the groundwater samples according to Cl, SO4 2-, CO32- and HCO3-, hardness(H), total dissolved solids (TDS), base-exchange, and meteoric genesis was demonstrated. Suitability of ground water samples for irrigation and industrial uses according to sodium adsorption ration (SAR), ratio of dissolved sodium (RDS), residual sodium carbonate (RSC) and saturation index (SI) was also investigated. The results of this study showed that almost all ground water samples were of good quality that makes them suitable for drinking and  domestic uses. Results also indicated that even though some of the ground water samples were suitable for irrigation purposes, almost all of them were found not be good for industrial uses. Despite all drawbacks of the sewerage system built around Sana’a secretariat at the beginning of the first decade of the third millennium, the results of this study indicate that there is scope of significant improvement in Sana’a secretariat ground water quality.

Hard rock aquifer is the most predominant in the southern peninsula exclusively in Tamil Nadu, India. Virudhunagar district is situated in the South west part of Tamil Nadu, mostly of hard rock topography. Groundwater plays a major role in this area contributing to domestic, irrigation and industrial practices. Running down of groundwater by extreme consumption and less recharge in the study area has reduced the level of groundwater. On the other hand, intensive domestic, agriculture and industrial practices impacts the quality of quality of groundwater as well. Hydro geochemistry plays an important role in evaluation of suitability of groundwater for its usage in several purposes. A total of 72 samples from North East Monsoon (NEM) and Post Monsoon (POM) has been analyzed hydrochemically. The irrigation quality parameters such as sodium adsorption ratio (SAR), %Na, Residual Sodium Carbonate (RSC), Kelley’s index and Magnesium hazard were calculated using CHIDAM software 2020 in conjunction with USSL and Doneen diagrams. During NEM, EC and TDS ranges from 273 to 5869 mg/L and 194 to 4159 mg/L and during POM is from 235 to 6850 mg/L and 233.8 to 6916 mg/L. The hydrogeochemical facies represents that Ca-HCO3 and mixed Ca-Mg-Cl facies are predominant during NEM and Na-Cl and mixed Ca-Mg-Cl are predominant during POM. The higher concentration of TDS and EC in the samples reflects the unsuitability of groundwater in both seasons.

The hydrochemical characteristics and the type of groundwater were identified in order to investigate the elements of major ions of groundwater samples in hydro-meteorology station located in Universiti Tun Hussien Onn Malaysia, UTHM. The objectives of the study were to measure the concentration of major ions and evaluate their chemical compositions . The measured ions were namely sodium (Na), magnesium (Mg), calcium (Ca), potassium (K), chloride (Cl), bicarbonate (HCO3), sulfate (SO4), heavy metals substance such as zinc (zn), ferum (Fe), copper (Cu), and manganese (Mn). Eight (8) groundwater samples were collected between January 2018 and March 2018 from a tubewell located at the Universiti Tun Hussein Onn Malaysia, Parit Raja, Johor followed by laboratory analyses by using Standard Methods for the Examination of Water and Wastewater. The concentrations of major cations and anions were determined and the concecutive strength were Na>Mg>K>Ca and Cl>HCO3>SO, respectively. Correlations among various pollutants were also observed. Strong correlations (p<0.01) were found between Total Dissolved Solid (TDS) and Electric Conductivity (EC). Both TDS and EC also showed strong positive correlations with Na, Mg, and Cl ions. The dispersal of major ions in groundwater was determined using piper diagram. The major cation and anion found were Na and Cl, respectively. The type of water that predominates in the study area was Na–Cl which indicated the groundwater influence from seawater intrusion. Mean concentrations for heavy metals parameters were also identified. The values milligram per litre (mg/L) were Mn (0.20), Cu (0.01), Fe (0.50) and Zn (0.04), respectively. Overall, the selected heavy metal parameters which were Mn, Cu, Fe and Zn met the Recommended Raw Water Standard by Ministry of Health, Malaysia.
