Good groundwater quality is essential for crop yield, soil productivity and environmental protection. Suitability of groundwater for irrigation purposes is determined by its geochemistry. Groundwater geochemistry explains links between chemical composition of groundwater and subsurface geological and non-geological pollutants. Subsurface rock formations control the composition of soil and hence that of water and vegetation. The ground water samples were analyzed for physico-chemical parameters like Electrical Conductivity (EC), Hydrogen ion concentration (pH), Bicarbonate (HCO3-), Calcium (Ca2+), Magnesium (Mg2+), Sodium (Na+), Potassium (K+), Sulphate (SO42-), Nitrate (NO3-), and Chloride (Cl-). Inverse distance weighted method of the Geographical Information Systems is used to prepare the distribution map of physio-chemical parameters of groundwater while overlay method is used to assess spatial, temporal changes and prepare groundwater quality zones of Walayar watershed in Parambikulam-Aliyar-Palar basin situated in Coimbatore district, Tamil Nadu, India. The results of study show that the quality of groundwater varies both spatially and temporally in Walayar watershed. The groundwater samples in some of the wells showed deviation from water quality standards indicating groundwater contamination. Hence, proper care must be taken to avoid any contamination of groundwater and its quality be monitored periodically.

Water plays a key role in the survival, growth and reproduction of aquatic organisms. Therefore maintaining good quality of water physico-chemical parameters would ensure optimum productivity of aquatic fauna. The study evaluated water physical and chemical parameters (temperature, hydrogen ion concentration (pH), conductivity, dissolved oxygen (DO) and biochemical oxygen demand (BOD) of Bodo Creek. Sample was collected for 5 months (July 2020 – November 2020) at locations previously studied (before-spill baseline studies, 3 years, 5 years, and 7 years after-spill); by using the sampling methods used in previous studies. Spatially, there was no statistically significant difference in temperature (p > 0.05 = 0.997), pH (p > 0.05 = 0.496), DO (p > 0.05= 0.34) and BOD (p > 0.05 = 0.644). However, the difference in conductivity between the stations was statistically significant (p < 0.05 = 0.006). On monthly basis, there was a significant difference in temperature (p < 0.05 = 0.000) and pH (p < 0.05 = 0.005). In contrast, there was no statistically significant difference in conductivity (p > 0.05 = 0.633), DO (p > 0.05 = 0.559) and BOD (p > 0.05 = 0.75). Most of the physico-chemical parameters were not within the WHO recommended levels for the survival of aquatic lives, indicating a high level of environmental pollution in Bodo Creek. This study provides dataset for future evaluation of the water physico-chemistry of Bodo Creek.

In this research work, hydro-geochemical characteristics were determined from twenty groundwater samples and classified into water quality zones on the basis of the World Health Organization (WHO 2006) using inverse distance weighted interpolation technique. Groundwater samples were analyzed with respect to calcium (Ca2+), magnesium (Mg2+), sodium (Na+), HCO3, total nitrate (NO2+NO3ˉ), chloride (Cl−), sulphate (SO42−), total dissolved solids (TDS), hydrogen ion concentration (pH) and electrical conductivity (EC) were measured form groundwater samples. The water quality indices (WQI1 and NPI = WQI2) were used to categorize the water. Water Quality Index (WQI) value suggest that the 65% groundwater samples (excellent + good) are safe for drinking uses and 35% groundwater samples (very poor + poor) needs treatment before consumptive uses from WQI1. Further, NPI (WQI2), shows 40% and 60% of groundwater falls under good and poor condition respectively. The findings highlight that the groundwater of few areas requires some degree of treatment before consumptive uses.

To assess the groundwater quality of the Paravanar river basin, groundwater data were collected by conventional methods. Hydrogeochemical facies of groundwater of study area reveals fresh to brackish and alkaline in nature. Piper plot shows that most of the groundwater samples fall in the mixed field of Ca-Mg-Cl type. Using GIS mapping technique, major element concentration of groundwater has been interpolated and studied. Groundwater thematic maps on electrical conductivity (EC), hydrogen ion concentration, bicarbonates, chlorides and nitrates were prepared from the groundwater quality data. Different classes in thematic maps were categorized as i) good, ii) moderate and iii) poor with respect to groundwater quality. Northeast and southeast parts of the study area represent the doubtful water class regarding the concentration of EC to represent connate nature of water adjacent to the coast. NNE (North-North-East) and southern parts of the study area have pH ranging from 7 to 8 indicating acidic nature as they were from the weathered Cuddalore sandstone. As northern part of the study area is irrigated, fertilizer used for agriculture may be the source for increase in concentration of nitrates. Chloride clusters in the south central part of the study area from coast up to NLC mines and reveals the chloridization of aquifer in 48 years either due to upwelling of connate water from the deeper aquifer as a result of depressurization of Neyveli aquifer for the safe mining of lignite.

Water is one of the most significant natural resources. In plants and animals, different physiological processes like respiration, photosynthesis, absorption of nutrients and other metabolic process get influenced by the amount of availability of water. This study has been conducted to evaluate water quality of Khaste Lake, Pokhara. After the collection of water samples, chemical parameters such as dissolved oxygen (DO), free carbon dioxide (F-CO2), hydrogen ion concentration (pH), total alkalinity (TA), total hardness (TH), total solid (TS), total dissolved solid (TDS), calcium (Ca), magnesium (Mg) and chloride ions (Cl-) have been measured in the chemistry laboratory, using standard methods prescribed by American Public Health Association (APHA, 1999) whereas the depth, transparency and temperature have been measured on the spot. The obtained values of physico-chemical parameters have been compared with the criteria of World Health Organization (WHO) and other lakes. The research reveals that all the abiotic components of the Khaste Lake meet the WHO standard of water quality. This research work concludes that the water quality of Khaste Lake is much less polluted and suitable for all the aquatic lives so far. Discharge of domestic sewage, use of fertilizers and pesticides in agriculture fields and other solid waste dumps can be the major threats for sustainability of the lakes. Awareness to the public and continual management need to be done to prevent the possibility of pollution and eutrophication process.

Abstract Municipal solid waste management has become an acute problem due to enhanced economic activities and rapid urbanisation. In most cities, solid waste is disposed of in open dumps without proper lining which has tremendous health issues and environmental effects. Kodungaiyur dump yard chosen for this study is the major toxic dump yard in Chennai. In recent years there has been a serious concern about the deteriorating groundwater quality due to leachate contamination. Despite posing strict rules on pollution of water bodies, water continues to be consistently underappreciated and undervalued. So, the present study is emphasized on the ill effects of leachate percolation on groundwater quality and is also represented spatially to understand the impact of the landfill in the selected area. For this study water samples are collected from 12 bore wells in and around Kodungaiyur dumpsite and they are tested for various Physico-chemical parameters like total alkalinity, total dissolved solids, hardness, conductivity, pH, sulphate, chloride, potassium, sodium, Magnesium, and nitrate. The water samples are also analysed for BOD, COD and heavy metals include Cd, Cu, Fe, Pb and Ni. The test results are compared with Water quality standards. The spatial distribution of the Physico-chemical parameters is represented in maps prepared using Quantum Geographical Information System (QGIS). The result obtained from testing and spatial representation using GIS helps in monitoring and managing water contamination in the study area.
