Hydrogeochemistry and groundwater quality assessment of Ranipet industrial area, Tamil Nadu, India

Abstract

India located at Ranipet occupies around 200 tanneries and other small scale chemical industries. Partially treated industrial effluents combined with sewage and other wastes discharged on the surface cause severe groundwater pollution in the industrial belt. This poses a problem of supply of safe drinking water in the rural parts of the country. A study was carried out to assess the groundwater pollution and identify major variables affecting the groundwater quality in Ranipet industrial area. Twenty five wells were monitored during pre-and post-monsoon in 2008 and analyzed for the major physico-chemical variables. The water quality variables such as total dissolved solids (TDS), Iron (Fe 2+), Hexavalent Chromium (Cr 6+), at most of the sampling locations exceeded the ISI and WHO guideline levels for drinking water. Multivariate statistical techniques such as factor analysis were applied to identify the major factors (variables) corresponding to the different source of variation in groundwater quality. The water quality of groundwater is influenced by both anthropogenic and chemical weathering. The most serious pollution threat to groundwater is from TDS, Cr 6+ and Fe 2+ , which are associated with sewage and pollution of tannery waste. The study reveals that the groundwater quality changed due to anthropogenic and natural influences such as agricultural, natural weathering process.

Investigation of contamination pathway and human health risk assessment from metals in milk from the cows grazing in an industrial area: a mass balance approach

“…Ranipet industrial area spreads over km and mushroomed with numerous tanneries, ceramics, pigments and paints, pharmaceuticals, refractories, chemicals and industrial hubs (Tamma Rao et al 2013). This is also the location of Tamil Nadu Chromate and Chemicals Limited (TCCL); which is reported to have 0.15 million tons of open dumps of Chromium wastes for decades; contaminating groundwater and soil in its vicinity to considerable extent (TNPCB 2010).…”

Accessible Phreatic Groundwater Resources in the Central Shijiazhuang of North China Plain: Perspective From the Hydrogeochemical Constraints

“…Concerns on groundwater chemistry and quality have been raised worldwide due to the worsening quality of groundwater in recent decades (Li et al, 2019;Alqahtani et al, 2020;Keesari et al, 2020;Liu et al, 2020). The poor quality of groundwater would greatly constrain the suitability of subsurface water for various uses by human society (Rao et al, 2013;Li P. et al, 2018;Qu et al, 2021a). Especially, some elements (such as fluoride, arsenic, nitrate, and heavy metals) in groundwater would pose adverse effects on the health of water consumers and induce many water-borne diseases like fluorosis, diabetes, cholera, dysentery, etc.…”

Risk Assessment of Groundwater Quality for Drinking Purposes During COVID-19 Pandemic Period Around Industrial Areas, Perundurai, Erode, Tamil Nadu, India

“…Signi cant studies have been carried out on groundwater quality assessment in this study area, but did not conduct the risk assessment of groundwater quality for drinking purposes using GIS technology and Statistical approach [Vinnarasi et al 2020]. The present study is supposed to generate awareness among the people of the study area about iron, uoride and chloride related problems due to minor and major elements contamination of water [Nitasha Khatri and Sanjiv Tyagi 2015].The nding of the study will be forwarded to the concerned authorities at district, state and national level for taking up the mitigation measures in iron, uoride and chloride affected areas of surrounding SIPCOT industrial estate, Erode district [Rao et al 2013]. Moreover, this study is important as there is very little information available about the groundwater quality of 15 km radius of Perundurai SIPCOT area is to provide safe drinking water to the people.…”
