The study focused to assess the groundwater in Madhavaram, Chennai, Tamil Nadu, for irrigational purposes. Irrigation indices like SAR, SSP, PI and KR was determined in each groundwater sample to identify its irrigational suitability. This study further envisaged that these groundwater aquifers have low Sodium adsorption ratio and hence groundwater is fit for irrigation, while residual sodium bicarbonate and Kelly’s ratio values indicated that majority of these aquifer have water of marginal to harmful quality against irrigation. The dominance pattern of cations in the studied ground water was in the order of Na > Ca > Mg > K and the sequence of anionic dominance was as follows: Cl > HCO3 > SO4. All 20 wells fall under the excellent category of SAR. SSP values of groundwater range from 49 to 71 and indicated that 15 wells are under permissible and 5 wells are under doubtful classification.  PI value indicated that groundwater is unsuitable against irrigation.  The KR indicated that groundwater quality in 18 wells is not fit for irrigation.  Hence, necessary pre-treatment methodology is to be adopted for utilizing groundwater for irrigation purpose.

Tiruppur is a textile city located on the banks of Noyyal River a tributary of the River Cauvery. Twenty groundwater samples were collected in identical locations from bore wells. The concentrations of physicochemical parameters of pH, Electrical Conductivity (EC), Total Hardness (TH), Ca, Mg, Na, K, HCO3, SO4, Cl and NO3 were analyzed. The results of the concentrations were interpreted and measured with different irrigation indexes like Percent Sodium (%Na), Sodium Adsorption Ratio (SAR), Residual Sodium Carbonate (RSC), Permeability Index (PI), Kelly’s Ratio (KR), CAI-1 and CAI-2 were analyzed.

Groundwater is generally used for various purposes, particularly domestic and industrial purposes in all over the world. Fresh water from groundwater sources is high in the recent years and the groundwater is polluted high because of rapid population and industrial growth. It is very difficult to restore the contaminated groundwater by various pollutants.  Hence, it is important to analyse physico-chemical parameters of groundwater for its need for various sectors. Therefore, the present study was under taken to define the quality of groundwater with the help of WQI. The ground water samples were collected from 20 different places around Ambattur Industrial Estate in Chennai city. The groundwater quality assessment showed that the water quality of bore wells around Ambattur Industrial Estate is poor for drinking purpose as per WQI for BIS acceptable limit.  WQI observed from those selected 20 groundwater bore wells are ranging from 63.30 to 219.63.   The analysis reveals that the groundwater from the Ambattur Industrial Estate needs pre-treatment before it is being used for various purposes.

Abstract Increasing population, erratic distribution of rainfall, and their rising demand for water in domestic and irrigation is fulfilled by groundwater resources. Due to overexploitation, there is the deterioration of groundwater quality and hence to evaluate the groundwater quality, a study was undertaken to understand the water suitability for drinking as well as for irrigation purposes. For this study, five villages namely Kumulur, Tachankurunchi, Pudurutamanur, Pandaravadai, and Poovalur were selected from Trichy District, Tamil Nadu, India with an areal extent of 45.1 km2. For the water quality assessment, samples were drawn from 53 locations from the sources like open well, bore well and hand pumps, etc., Parameters of pH, EC, TDS, Anions - CO3 2−, HCO3−, Cl−, SO4 2−, Cations - Ca2+, Mg2+, B3+, Na+ and potassium (K+) were estimated using the standard analytical procedure in three different seasons Viz., S-I (September 2019), S-II (December 2019) and S-III (March 2020). The WQI was computed for drinking water quality and it was found that 25% samples in S-I, 80% samples in S-II, and 83% samples in S-III were above the permissible limit for drinking purposes. Indices like Sodium Percentage, Sodium Adsorption Ratio, Permeability Index, Kelly’s Ratio, Magnesium Hazard Ratio, Potential Salinity, USSL Diagram, Wilcox Plot, Piper Diagram, and Gibbs plot were evaluated for examining irrigation water quality. The results revealed that 90% of the area, the water is suitable for irrigation purposes and a few locations (10%) wherein the salt content of water are relatively higher than the entire study area.

Abstract The present work was carried out in the deltaic region of the river Godavari in Coastal Andhra Pradesh of Southern India to evaluate the status of groundwater quality for irrigation. Groundwater is predominantly used in these productive agricultural fields. Saline water intrusion in fresh groundwater aquifers was recorded in the study area which is mainly due to the excess withdrawal of groundwater. A total of 80 groundwater samples were analyzed for various physical and chemical parameters using standard chemical procedures. The groundwater mainly represents sodium-chloride type which exhibits the mixing of fresh water with the saline water. The high correlation between Na+-Cl− and Mg2+-HCO3− explained that the intermixing of aquifer waters and the leaching of secondary salts. The mechanisms of groundwater have been shown mainly evaporation-fractional crystallization process. The irrigation water quality index was calculated by using different quality indices such as Na%, SAR, RSBC, PI, MH, KR, PS, Cl−:HCO3−, Mg2+:Ca2+, and Na+:Ca2+ to estimate the suitability of groundwater quality for irrigation. Spatial distribution maps were prepared using raster interpolation in GIS. The assessment revealed that the areas covering 67.6% of electrical conductivity, 100% of total dissolved solids, 57.5% of percent sodium, 21.3% of residual sodium bicarbonate, 66.3% of permeable index, 16.3% of magnesium hazard, 65% of Kelly's ratio, 100% of potential salinity were required severe to moderate restrictions. Overall, the groundwater in the study region showed potential salinity due to geogenic and anthropogenic activities thus it must be monitored for sustainable agriculture.
