Most people in Tanah Bumbu Regency use water from dug wells for their daily activities. Kotabaru Regency is located in Pagatan Groundwater Basin, which is located in three administrative boundaries, namely Tanah Laut Regency, Tanah Bumbu Regency, The purposes of this study are to determine the type of groundwater facies and Water Quality Index (WQI). The methods were hydrogeological mapping and hydrogeochemical analysis of groundwater samples to evaluate groundwater quality. There were 170 groundwater samples mapped in the study area. The study area has differences in groundwater quality in both confined aquifer and unconfined aquifer. The unconfined aquifer has two types of groundwater facies, namely Ca-Mg-HCO3 (Calcium Magnesium Bicarbonate) and Ca-Cl (Calcium Chloride). In comparison, the confined aquifer has two types, which are Ca-Mg-HCO3- (Calcium Magnesium Bicarbonate) and Na-HCO3- (Sodium Bicarbonate). Based on the calculation of the Water Quality Index (WQI) of unconfined aquifer samples show that 70% of groundwater samples have poor quality. Meanwhile, the confined aquifer samples indicate that 85% of groundwater samples have good to excellent, which is suitable for drinking water.

In the present study, fifty-five groundwater samples were collected from the parts of the Jalna district of Maharashtra, India. The water samples were analyzed to determine various physic-chemical parameters like pH, electrical conductivity, total dissolved solids, total hardness, alkalinity, chloride, sulphate, calcium, magnesium, sodium and potassium. The groundwater’s geochemical control and hydrogeochemistry were evaluated using the Piper plots and water quality index (WQI). The hydrochemical analysis reveals that the groundwater is predominantly of CaNaHCO3 type, Water quality index (WQI) indicates that 33% and 2% of groundwater samples fall in poor and very poor categories for drinking purposes. This study reveals that groundwater quality is unfit for drinking purposes at a few places. The effective leaching, dissolution process and rock-water interaction process are the main sources for degrading the groundwater quality.

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

The quality of groundwater resources is increasingly declining, significantly affecting people’s life and health. The study aims to assess public perception on existing groundwater quality and scheme over conventionally used free groundwater. The contemporaneous analytical procedures applied to determine the concentration of physical parameters: total dissolved solids and total solids and chemical parameters: pH, nitrite (N-NO2-), nitrate (N- NO3-), ammonium (N-NH4+/ NH3), iron (FeII + III) and total hardness were collected for 30 drinking water well samples located in 5 Quarters (An Hoa, An Loi, Ben Don, Phu Hoa, and Phu Nghi) to calculate the water quality index. The results show that up to 96% of people still use groundwater as their main source of drinking, domestic purposes, although groundwater quality is showing a serious decline in quality. The low pH index ranges from 3.0 ÷ 4.5. On average, 3.5 ÷ 4.0 pH of groundwater samples are outside the permissible limit according to VN standards 09: 2015 (5.5 - 8.5), which makes the water acidic, which harmful to human health. Besides, 10% of groundwater samples had high nitrate content, and 6.67% of water samples had ammonium content that did not meet VN standards 09: 2015. The current state of groundwater quality is not good for cooking and drinking. The results will benefit future groundwater exploitation to support more evidence of water quality and deteriorate the water quality soon, ultimately proving to be disastrous for all living beings in the region.

Drinking Purpose

Water Quality Index (WQI) is a mathematical value for quality of water, which includes the concentration of a number of constituents present in it. Chemical and biological measures of water quality are used to represent water quality index. Measured value of the selected parameters, ideal concentration of that parameter in pure water and standard value given by different quality control organizations are used to determine this number. In the present study, three indexing methods; Weighted Arithmetic Water Quality Index (WAWQI), Groundwater Quality Index (GWQI) and Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) were used to calculate water quality index of groundwater. A hydrochemical analysis of 22 groundwater samples was conducted to evaluate the quality of groundwater for drinking purpose. Ten hydrochemical parameters were selected for computing WQIs of groundwater samples and BIS standards were used for standardization. Analytical results show that 100 % of samples have magnesium and total hardness above the acceptable limit of BIS (10500, 2012). The mean concentration of nitrate was found 196.96 ± 9.3.18 mg/L. Spatial distribution of various parameters shows that south-east part of study area has contaminated groundwater. The results of water quality index shows that drinking water quality of 82 % (WAWQI), 95 % (GWQI) and 77 % (CCME WQI) of groundwater samples were poor to unsuitable type. Water quality index map also reveals that groundwater of village Badhpura, Dhoom Manikpur, Dairy Maccha, Khera Dharampura, Bisrakh road, Duryai and Dujana of district Gautam Budh Nagar of India, was not fit for human consumption.

This present hydrological study assessed the groundwater quality of Biratnagar Metropolitan by the application of Water Quality Index (WQI). It has been determined on the basis of analyzed groundwater samples for some important physicochemical parameters such as pH, turbidity, electrical conductivity (EC), dissolved oxygen (DO), free carbon-dioxide (FCO2), bicarbonate (HCO3), total hardness (TH), phosphate (PO4-P), nitrate-N (NO3-N), arsenic (As), and fluoride (Fl) collected from 110 representative tube wells during post-monsoon period of 2015. The status of fluoride was below detectable level (BDL) in all the analyzed groundwater samples. The WQI for these samples ranged from 84.54 to 403.14. The high value of WQI has been found mainly due to the higher values of turbidity, FCO2 and arsenic in the groundwater. The results of study have been used to recommend models for predicting water quality. The classification of water quality on the basis of WQI value have been found to be good water (18.18%), poor water (59.09%), very poor water (13.64%) and unsuitable for drinking (9.09%). The result of the study suggests that the groundwater of the area needs some degree of treatment before consumption, and it also needs to be protected from the threat of contamination. The groundwater is one of the major source of drinking water as well as for irrigation in study area.

Urbanization and industrialization enhance the degradation of the groundwater quality due to the discharge of domestic and industrial effluents in the aquatic bodies or on the surface of ground either in treated or untreated form. Therefore, the present study was carried out to assess the groundwater quality at the Laksar block of district Haridwar in Uttarakhand. Groundwater samples (SS-1-10) were collected from the hand pumps of the study area. The sampling site (SS-1) was taken as control. The distance of all sampling sites from control site ranged from 6.3Km to 18.3Km. The samples were analyzed for various physicochemical parameters viz Temperature, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Total Solids (TS), pH, Dissolved Oxygen (DO), Total Hardness (TH), Calcium Hardness (CaH), Chloride (Cl), Sulphate (SO4--), Nitrate (NO3---), Acidity, and Iron (Fe) for two years (2017 to 2019).  The data obtained after analysis was simplified using Water quality index (WQI). The maximum concentration of TDS, TS, TH, CaH, and Fe was observed at SS-6 that may be due to the direct industrial discharge of Sugar mill effluent on the ground. Based on WQI value, SS-6 (WQI value-150.27) was found most polluted site. Hardness was found above the standard limit (250mg/l) at SS-6 to SS-10. The Fe was also found above the standard limit of WHO and BIS (0.3mg/l) at SS-6 to SS-10. The study may be useful for managing the groundwater quality of the study area.

The aim of this work is to assess the groundwater quality in Pengyang County based on an improved water quality index. An information entropy method was introduced to assign weight to each parameter. For calculating WQI and assess the groundwater quality, total 74 groundwater samples were collected and all these samples subjected to comprehensive physicochemical analysis. Each of the groundwater samples was analyzed for 26 parameters and for computing WQI 14 parameters were chosen including chloride, sulphate, pH, chemical oxygen demand (COD), total dissolved solid (TDS), total hardness (TH), nitrate, ammonia nitrogen, fluoride, total iron (Tfe), arsenic, iodine, aluminum, nitrite, metasilicic acid and free carbon dioxide. At last a zoning map of different water quality was drawn. Information entropy weight makes WQI perfect and makes the assessment results more reasonable. The WQI for 74 samples ranges from 12.40 to 205.24 and over 90% of the samples are below 100. The excellent quality water area covers nearly 90% of the whole region. The high value of WQI has been found to be closely related with the high values of TDS, fluoride, sulphate, nitrite and TH. In the medium quality water area and poor quality water area, groundwater needs some degree of pretreated before consumption. From the groundwater conservation view of point, the groundwater still need protection and long term monitoring in case of future rapid industrial development. At the same time, preventive actions on the agricultural non point pollution sources in the plain area are also need to be in consideration.

Abstract This study focused on hydrogeochemical characterisation and groundwater quality deterioration based on drinking, irrigation purposes in Pudukottai district. Eighty-seven groundwater samples were collected from the bore and dug wells during pre and post monsoon seasons in the year 2019. The order of mean abundance of ions is followed as C l > HCO3 > Na > SO4 > Mg > Ca > K (325.5 > 182.2 > 181.4 > 83.2 > 51.1 > 35.8> 9.1 > 8.6 > o.9 > 0.3) and Cl > Na > HCO3 > SO4 > Mg > Ca > K (415.7 > 230.3 > 198.2 > 82.9 > 53.8 > 43.4 > 14.9) in both seasons. Analytical results are used in Piper, Gibbs, Na% vs. EC, USSL, and PI to evaluate the hydrogeochemical processes. Rock water interaction and evaporation processes causing variations in hydrogeochemistry of the study area during pre and postmonsoon. Nearly 15 % of the groundwater samples were not permissible for drinking based on the standard, which is distributed in south eastern region of the study area. It is revealed from Na%, SAR, RSC, MgC and KR results that majority of the groundwater samples are fit for irrigation uses. The higher concentration of EC, TDS, Cl and Na values noted in south region due to the sea water intrusion that attributed by excess pumping in the coastal regions. The drinking water quality index (DWQI) and irrigation water quality index (IRWQI) are calculated to identify the suitability of groundwater for drinking and irrigation purposes. However, this research concludes that the groundwater quality of maximum part in the district is appropriate for drinking as well as agriculture which can be used for the sustainable growth. It is also recommended implementing the artificial recharge techniques to improve the groundwater quality.

This study takes a look into groundwater quality at Ugbor Dumpsite area using water quality index (WQI), 2-Dimensional (2-D) geophysical resistivity tomography and vertical electric sounding (VES).The geophysical resistivity methods employed revealed the depth to aquifer, the geoelectric layers being made up of lateritic topsoil, clayed sand and sand. Along the trasverse line in the third geoelectric layer of lateral distance of 76 m to 100 m is a very low resistivity of 0.9 to 13 m from a depth range o f about 3 to 25 m beneath the surface- indicating contamination. Water samples were collected and analyzed at the same site during the raining season and during the dry season. The value of water quality index during the raining season was 115.92 and during the dry season was 147.43. Since values at both seasons were more than 100, it implies that the water is contaminated to some extent and therefore poor for drinking purpose. The Water Quality Index was established from important analyses of biological and physico-chemical parameters with significant health importance. These values computed for dumpsite area at Ugbor were mostly contributed by the seasonal variations in the concentrations of some parameters, such as, conductivity, total dissolved solids, hardness, alkalinity, chlorides, nitrates, calcium,  phosphates, zinc, which showed significant differences (P<0.01 and P<0.05) in seasonal variation.
