Abstract:

Adverse effect of rapid industrialization on groundwater quality and quantity is widely known problem especially in developing countries. Komarapalayam, which is situated on the bank of Cauvery & Bhavani River in India, is known for intensive textile processing activities. As groundwater is the main water source for drinking water, there is an urgency to assess the groundwater quality. Twenty groundwater samples were collected for each post and premonsoon sampling during October 2015 and November 2015, respectively. Chemical and statistical analysis along with numerical modeling has been performed to assess the current status. The hydro-geochemical study revealed that the dominance of Mg–Cl and Na– HCO3 groundwater type in the upstream region Komarapalayam industrial hub of Kauvery River basin. Na–Cl groundwater type was found increasing in industrial hub and downstream of the industrial hub sites. The dominance of Na–Cl type of water is mainly due to the impact of salts like NaCl, Na2SO4, etc. used in textile processing, which after discharge, percolate and accumulate in the aquifers. Seasonal groundwater quality of Komarapalayam region as a whole showed the dominance of Ca–HCO3 - , Na– HCO3 - and Na–Cl water types. The output indicates that nearly all the groundwater samples were over saturated with respect to calcite and dolomite and under saturated with respect to gypsum and halite. The results obtained in this study were then compared with groundwater quality of the Kauvery River basin for the year 2008–2009. Among the two sites, Komarapalayam was found to be most contaminated due to incessant industrial discharge. But with the advent of new treatment technologies like CETPs having zero liquid discharge system and MBR, there has been slight decline in the concentration of different physicochemical parameters from 2002–03 to 2008–2009.
