AbstractThe present study focused on the seasonal investigation of hydro-geochemical characteristics of groundwater samples collected from the vicinity of three tributaries of the Beas River, Punjab, India. Total 45 samples were analyzed during the pre- and post-monsoon season for physico-chemical parameters and heavy metals along with health risk assessment. Results revealed that the majority of samples were below the permissible limits set by the BIS and WHO. The relative abundance of major cations was Ca2+ > Mg2+ > Na+ > K+ and Ca2+ > Na+ > Mg2+ > K+, while that of the major anions was HCO3− > SO42− > Cl− > CO32− in the pre- and post-monsoon season, respectively. Groundwater was alkaline and hard in nature at most of the sites. Bicarbonate content exceeded the desirable limit having an average concentration of 337.26 mg/L and 391.48 mg/L, respectively, during the pre- and post-monsoon season. Tukey’s multiple comparison test was applied for finding significant differences among samples at p < 0.05. The dominant hydrochemical face of water was Ca–Mg–HCO3 type. US salinity (USSL) diagram indicated that during the pre-monsoon, 48.9% samples were C2S1 type and remaining 51.1% were C3S1 type while during the post-monsoon all samples were C3S1 type. It indicates that groundwater of the study area is at risk of salinity hazards in future and is not to be ignored. Such monitoring studies are recommended to design future safety plans to combat soil and human health risks.

Belchampa-Pratappur villages about 8 Kms towards East from district head-quarter Garhwa has been undertaken to study the groundwater quality, especially fluoride contamination. These places are situated on the border of the Garhwa and Palamu district. Bishrampur is the prominent place lying to about 11 km east of area under consideration. The area is underlain mostly by granite and gneisses. Fluoride containing minerals as indeed Fluorite, apatite, different amphiboles and micas occur in association with these rocks. 18 Groundwater samples during Pre-and Post-monsoon have been collected from tube wells and analyzed for major cation ( Ca+2,Mg+2,Na+,K+) and anion(HCO3-, Cl-,SO42-,F-) in addition to fluoride. Fluoride concentration as high as 5 mg/l has been found in many samplesof groundwater in the area, which is above the admissible limit of 1.5 mg/l (WHO). The inhabitants of these two villages belong to very poor economic background and of diverse communities. Many people of these villages are fluoride affected. Dental and Skeletal fluorosis is common in the area, which is very alarming. The total dissolved solid (T.D.S.) is also found to be much higher, at many places. It ranges from 586 mg/l to 408 mg/l in pre-monsoon and 736 mg/l to 194 mg/l in post monsoon season respectively. Consequently the electrical conductivity is also much higher at several places which ranges from 915 micro mhos/cm to 637 micro mhos/cm at 250C in pre-monsoon and 1150 micro mhos/cm to 303 micro mhos/cm in post-monsoon season respectively.

High altitude lakes are very sensitive to climate change due to their small catchment area, limited vegetation cover, surface water with low nutrients, and thin soil and low bedrock weathering rates. The present study was focused on high altitude Himalayan Lake Gosainkunda, situated at an elevation of 4300 m in the Langtang National Park, and carried out during the post- monsoon season (October) in 2010. The main aim of the study was to assess the water quality quantitatively considering the anthropogenic as well as natural impacts in the lake. The water samples were collected at six different sites to represent entirely the quality of the lake. The sampling sites were systematically designated as the inlet, outlet, human influence site, littoral zone, middle (central) and the deepest part of the lake. Some major cations (Ca++, Mg++, Na+ & K+) and anions (Cl-, SO4 — & HCO3 -) were analyzed; the cation type is dominated by Ca++ (64%) while the anions are dominated by Cl- (49%). Among the trace elements (Al, Fe, Mn, Zn, Cu, Cd, Cr, Ni, Pb & As), except for Al and Fe, all others were found below the detection limit.

AbstractHydrogeochemical investigations have been carried out in a semi-arid region of Aland taluk of Karnataka State, India. The analysis has been done to examine the quality of groundwater for drinking, domestic and irrigational purposes. In this concern, thirty-two groundwater samples were collected in pre-monsoon (April 2016) and post-monsoon season (November 2016), from the different location within the study area. These samples have been further analysed for different ions such as CO32−, HCO3−, NO3−, Ca2+, Mg2+, Na+, K+ Fe2+, SO42−, Clˉ and F− to evaluate the hydrochemical behaviour with SSP (sodium soluble percentage), SAR (sodium absorption ratio), % Na (percentage sodium), RSC (residual sodium carbonate), KR (Kelly’s ratio), PI (permeability index) and MH (magnesium hazards). These positive and negative ions have been further correlated with the maximum annual rainfall within the study area to find out the variations between these ions for the precipitation. Suitability of groundwater for drinking purposes around the catchment was not suitable except in a few places. Irrigational suitability of groundwater showed that the water is within the limit for irrigation except in a few locations. Wilcox diagram depicts that 90% of the pre-monsoon samples and 65% of the post-monsoon samples fell into excellent to good category zone. US salinity diagram explains that 71% of pre-monsoon samples belong to medium-salinity-hazard to low-sodium-content zones, whereas 50% of post-monsoon samples fall into high-salinity-hazard to low-sodium-content zone. Gibbs’s plot showed that the water–rock processes control the geochemistry of the Aland region in both monsoon seasons. Chadha’s diagram depicts that 56.25% of the groundwater samples fall under the subfield of Ca2+–Mg2+–Cl− water type with permanent hardness during pre-monsoon season, whereas 50% of groundwater samples falls under the subfield of Ca2+–Mg2+–HCO3− water type with temporary hardness during post-monsoon season.

Abstract The Intrusion of saltwater into a freshwater aquifer is of particular concern to the coastal community. Removal of excess groundwater from the shallow aquifers is known to be the primary cause of contamination by saltwater. In this study, groundwater samples were obtained in the 2016 and 2017 pre-monsoon and post-monsoon seasons at 105 locations from dug wells and bore wells along the coast of Andhra Pradesh in the Krishna and Godavari deltas. Groundwater samples are tested for large ions to determine the infiltration of salt water and to classify the salinity sources in the delta zone. The Various hydro-geochemical parameters such as pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Ca2+, Mg2+, K+, Na+, CO3, HCO3-, Cl-, and SO42- are evaluated for the delineation of the intrusion of saltwater in terms of Ca2+/ Mg2+, Cl-/(CO3+ HCO3-), Na+/Cl- ratios. It is reported that the availability of fresh groundwater is 14%and 62% respectively during the pre-monsoon and post-monsoon seasons. The percentage levels of contamination in groundwater for slight, moderate, injuriously, highly, and severely categories are 43%, 22%, 12%, 8%, and 1% respectively for pre-monsoon season. However, during the post-monsoon season, the levels of contaminations in the above- mentioned categories are 22%, 9%, 4%, 1%, and 3%. The extent of contamination during the post-monsoon season is observed to be lower than during the pre-monsoon. The groundwater ratio of Na+- Cl− during pre-monsoon and post-monsoon seasons is 71%and 60% respectively. The Saltwater Mixing Index (SMI) is also measured, and extremely high is found.

Abstract Hazardous compounds in aquifers, especially potentially toxic heavy metals, are a major environmental and socioeconomic problem around the world. Hence, the study is intense to quantify, for the first time, the pollution status and ecological risk of heavy metals around inactive mining sites in the Southwestern (SW) region of Cuddapah Basin. Ten heavy metals, including arsenic (As), cobalt (Co), cadmium (Cd), iron (Fe), chromium (Cr), nickel (Ni), manganese (Mn), lead (Pb), zinc (Zn) and strontium (Sr) were investigated for a total of 50 groundwater samples of this study. The findings of the study revealed that arsenic (0-60.5 and o.56.3 µg/L), cadmium (0-28.1 and 0.31.1 µg/L), nickel (0-110.2 and 0–99 µg/L)), lead (0-175.6 and 0-92.3), Strontium (0-1150 and 0-1440 µg/L) concentrations are above the acceptable levels in both pre and post – monsoon seasons. The Heavy Metal Pollution Index (HPI), Heavy Metal Evolution Index (HEI) and Degree of contamination (DOC) are applied to assess hazardous metal pollution in drinking water of this area. According to HPI values 17.5 % and 10% of samples fall under high pollution index; as per the classes of HEI, 95 % and 100% of samples fall under low pollution class during the pre and post-monsoon season. According to DOC, all groundwater samples fall in a low zone. As per ecological risk classification, 90% of the samples cause extreme high ecological risk in pre & post-monsoon season in the study area.

Abstract In most regions of the present study area, Bhavani Taluk, groundwater quality is deteriorating at an alarming rate as a result of anthropogenic activities, however, little attention was given to groundwater quality and management. This research examines the quality of groundwater in Bhavani Taluk, Tamilnadu and compares its suitability for irrigation. The Bhavani region of Erode District, Tamilnadu is the most cultivated, with a considerable use of fertilizers and pesticides. Groundwater quality for irrigation purposes was assessed during the pre-monsoon season by collecting samples from 53 different locations. Physico-chemical parameters such as pH, EC, TDS, HCO3−, CO32−, Cl−, SO42−, NO3−, Ca2+, Mg2+, Na+ and K+were measured in these groundwater samples. Irrigation quality measures such as salinity hazard, sodium hazard expressed as SAR, percentage of sodium (% Na), and permeability index (PI) were calculated to evaluate groundwater quality for agricultural irrigation. Based on the classification of Electrical conductivity (EC) most of the groundwater samples are falling under the permissible limit. As per the USSL diagram, the large majority of groundwater samples fall within the category of C3-S1 and the water is suitable for irrigation. Piper trilinear diagram interpretations were made to know the chemical type of the groundwaters. The piper diagram indicates that 50% of the groundwater sample were belongs to Mg2+, Ca2+, HCO3−, and Cl−. The groundwater samples fall under Class I category according to Doneen’s Classifications.
