Spatial assessment of groundwater quality in Mamundiyar basin, Tamil Nadu, India

Abstract

Understanding the groundwater quality is important as it is the main factor determining its suitability for drinking, domestic, agricultural, and industrial purposes. In order to assess the groundwater quality, 30 groundwater samples have been collected in year 2008. The water samples collected in the field were analyzed for electrical conductivity, pH, total dissolved solids (TDS), major cations like calcium, magnesium, sodium, potassium, and anions like bicarbonate, carbonate, chloride, nitrate, and sulfate, in the laboratory using the standard methods given by the American Public Health Association. The groundwater locations were selected to cover the entire study area and attention was been given to the area where contamination is expected. The expected groundwater contaminants were chloride, nitrate, TDS, etc. The results were evaluated in accordance with the drinking water quality standards given by the World Health Organization (WHO 1993). To know the distribution pattern of the concentration of different elements and to demarcate the higher concentration zones, the contour maps for various elements were also generated, discussed, and presented.

“…The high NO − 3 groundwater content (sampling sites 15, 16, and 20) is the result of dissolution of fertilizers and the leakage of municipal sewage. Moreover, according to Dar et al (2010) the NO − 3 is the most frequently introduced pollutant into the groundwater systems.…”

“…Overdependence on groundwater to meet the ever-increasing demands of domestic, agriculture, and industry sectors has resulted in the overexploitation of groundwater resources and deteriorated the quality in many states of India (Machiwal, Jha, & Mal, 2011). Several studies were conducted in different parts of the country by a large number of researchers to evaluate the groundwater quality and its suitability for various purposes, spatial distribution, chemical composition, saline intrusions, groundwater-surface water interactions and groundwater vulnerability (Elango, Kannan, & Senthil Kumar, 2003;Subramani, 2005;Srinivasamoorthy et al, 2011;Vasanthavigar et al, 2010;Dar et al, 2011;Kumari, Singh, Verma, & Yaduvanshi, 2014;Gulgundi & Shetty, 2018). Identification of the factors affecting groundwater quality needs to be done using suitable evaluation methods.…”
