Groundwater samples of bore wells (BW), open wells (OW), Hand Pumps (HP), lakes, falls and streams collected from different locations in Yercaud Taluk in Salem District, Tamil Nadu were analyzed for their physicochemical characteristics. The ground water samples were studied during pre-monsoon (June-July 2010) and post-monsoon (December 2010-January 2011) seasons from 25 different villages. The present study was undertaken to characterize the physicochemical parameters such as temperature, pH, Total Alkalinity (TA), Electrical Conductivity (EC), salinity, Calcium Hardness (CH), Magnesium Hardness (MH), Total Hardness (TH), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Total Solids (TS) and fluoride. Each parameter was compared with its standard permissible limit as prescribed by World Health Organization (WHO). The Water Quality Index (WQI) reflected that most of the samples are of good and excellent quality. The Karl Pearson Correlation matrix has approved the influence of CH on EC, Salinity and TDS with significantly positive correlation. The study reveals that all the villages have hardness within the desirable limit prescribed by WHO.

REST Publisher , 2023
A fundamental natural resource is water, which is essential to life. The increasing urban isation of India has an impact on the quantity and quality of groundwater. According to the Central Ground Water Board, the groundwater beneath Krishnagiri has been reduced by 60%, and additional investigation may reveal salt water intrusion. Our goal in the current work was to investigate groundwater quality assessment.This investigation's goal was to assess Krishnagiri City's groundwater's level of quality. The quality of groundwater determines whether it is suitable for use in industrial, household, agricultural, and drinking water applications. Evaluation of Groundwater Suitability in the Northern and Eastern Krishnagiri District for Irrigation and Drinking Water. Groundwater samples were taken in the research region. In Tamil Nadu's fluorosis-prone Krishnagiri area, water samples were taken from ten villages. Numerous physico-chemical indicators of water quality, including pH, TDS, TH, Ca2+, Mg2+, Na+, K+, Cl, and fluoride (F), have been measured and compared to typical values (WHO and BIS). Groundwater quality has been evaluated by looking at physicochemical elements such pH, TDS, TH, sulphate, chloride, calcium, and magnesium. A substantial linear association between several water quality metrics is revealed by the investigation. Version 16 of the SPSS statistical analysis programme was utilised for the analysis. The outcomes showed that the groundwater's pollutants were almost at the allowable levels. With a few notable exceptions, the bulk of the criteria used to evaluate the water quality showed levels within the range permitted by the Bureau of Indian Standards (BIS). None of the measurements exceeded the BISrecommended allowed thresholds for determining the water quality, with the exception of pH at a specific point in Zone 1.

2024
A hydro-geochemical study for water-quality assessment was conducted in the Tuticorin region of Tamil Nadu in southern India during the pre-and post-monsoon seasons of 2022 and the water samples are examined to comply with BIS and WHO guidelines. In the present study, the values of TDS (75%), Mg (37.5%), and TH (25%) have exceeded the permissible limits namely 500, 100, and 600 mg/L, respectively. The WQI proposed by CCME is used to analyze water suitability. The Pearson correlation and principal component analysis are used to study the relationship between various physicochemical parameters and principal components of water quality, respectively. Piper & Gibbs diagrams are plotted to identify the water types and the main water type predicted by the piper plot is Ca-Mg-Cl-SO 4 which makes up 74.3% of the the samples studied. WQI suggests that 22.5% and 50.0% specimens have excellent water quality during pre and post-monsoon seasons, respectively.

Ground water contamination has become very important issue of concern these days. People of Bihar mostly use ground water sources for household and agricultural needs. In Mohuddinagar block people are dependent on agriculture for their livelihoods and groundwater was the major source. An inclusive assessment of ground water resources was done in the study area from 12 station points in the month of November,2021. The study was done to understand hydrogeochemical facies of groundwater along with the suitability of groundwater in household and for agricultural needs. The physico chemical parameters of water including EC (Electrical conductivity), TDS (Total dissolved solids), pH, major cations and and anions was investigated. The outcomes were compared with the Bureau of Indian Standards-2012. Among heavy metals Arsenic and Iron were tested in water samples and the map showing the distribution of these heavy metals was created. The analysis of samples was done based upon APHA standard methods. Piper trilinear diagram and Chadha's plot represented different hydrogeochemical facies of the groundwater. The SAR, Na% and RSC values were calculated to assess its suitability for agricultural purposes. Most of the statistical operations were done using MS-EXCEL software. Except few all the major ions were found to be present within the prescribed limits of Bureau of Indian Standards-2012. As and Fe concentration at some sampling locations was found to be beyond the permissible limits. In the study area Mg 2+-Ca 2+ − HCO3and Mg 2+-HCO3-Clwere dominant hydrochemical facies. For agriculture purpose 50% of the water samples had high salinity and it needs to be managed before use in irrigation, it is represented by US_salinity diagram. Wilcox plot represented the relation between Na% and EC and it was concluded that groundwater of study area falls under following categories: • Excellent to good • Good to permissible quality and so it can be used for irrigation purposes.
WATER QUALITY INDEX FOR GROUNDWATER IN CHENNAI, TAMILNADU, INDIA
A tremendous increase in the demand for freshwater due to rapid growth of population, urbanization and the accelerated pace of industrialization act as a main driving force for altering local and regional hydrology. It is noted that in Tamil Nadu, there is evidently much dependence on groundwater due to scarce surface water. Overexploitation of groundwater might lead to complex environmental situation. Hence, a thorough investigation of quality parameters is necessary to ensure the potability of water. The objective of the present study is to analyze the various parameters of ground water and to assess the quality of ground water using water quality index for the region of Karayanchavadi in Chennai, Tamil Nadu, India. The study area has been categorized as Residential, Residential with Part Industry, Residential with Part Crop Cultivation area and Crop Cultivable area. Groundwater samples were collected from each zone for two years duration and analyzed for physico-chemical parameters following standard methods and procedures. The results obtained are compared with WHO standards. The results of the study reveal that most of the parameters in the study area are within the permissible limits. Water Quality Index suggests that water is suitable for domestic purposes.

Pollution Research
Groundwater has been considered as an important source of water supply due to its relatively low susceptibility to pollution in comparison with surface water, and its large storage capacity. It should be mentioned that water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives (in) it. When humans drink polluted water it often has serious consequences on their health. Water pollution can also make water unsuited for the desired use. In this context, an attempt has been made to assess the ground water quality of Ujjain city. Samples were collected from 17 locations of Ujjain city from various ground water sources for summer season and analysed for physico-chemical parameters .The results of analysis were compared with the Indian standards (BIS, IS 10500:1991) of drinking water quality parameters. The pH values of all samples indicate with in desirable limit. Turbidity, alkalinity, t...

Groundwater samples (n=15) were collected from various sites of Shah Faisal Town from a variable depth range (70-400 feet). The TDS varied from 766.08 to 5490.24 mg/L with a mean of 3128.16 mg/L. Circum-neutral pH (6.84-7.56) is evident within the WHO guidelines (6.5-8.5) for drinking. All the samples have objectionable (> 500 mg/L) level of hardness content where it shows a wide range (600-1800 mg/l; mean: 1200 mg/l). The samples ' sodium content (Range: 200-1223; mean: 711.5 mg/L) exceeded WHO limit (200 mg/L). Calcium and magnesium concentrations varied between 40-240 and 92.34-340.2 mg/l with a mean of 220 mg/l and 216.27 mg/l, respectively. Both these elements exceed about 5 times the corresponding permissible limits set by WHO for drinking water. On the other hand, two third samples show elevated bicarbonate content (Range: 210-500; Mean: 355 mg/l). Similarly, nitrate varies between 3.758-14.2 mg/l with a mean of 8.97 mg/l. Fluoride concentration varies between 0.78-1.65 mg/L with a mean of 1.215 mg/L where only 2 samples exceed WHO limit (1.5 mg/L). The water quality index (WQI) is found to be87.32 which suggests that the groundwater is very poor and only suitable for irrigation. It is concluded that about half of the samples failed to meet the water quality criteria set by WHO for drinking. The problem is aggravated due to anthropogenic activities mainly by sewage infiltration and water supply conditions.
