A Comprehensive Geochemical Evaluation of the Water Quality of River Adyar, India

Abstract

The River Adyar flows through the fault of south Chennai for about 50 Km and enters into the Bay of Bengal. This river is almost stagnant and do not carry enough water except during rainy season. Rapid industrialization and urbanization along the river course during 80s and 90s of last century has increased the pollution of the river water. The main objective of this study is to identify and assess the nature of pollution. In order to achieve this objective, necessary geochemical parameters were determined and the quality of water is evaluated using various tools, such as Wilcox diagram, USIS, Piper, sodium absorption ratio (SAR), 3D scattered diagrams, and seasonal variation diagrams. The monsoonal variations in the data matrix of the river water (River Adyar) was monitored at 33 stations for the premonsoon and postmonsoon periods during September 2005 and February 2006.

Multivariate statistical techniques for the evaluation of surface water quality of the Himalayan foothills streams, Pakistan

“…In contrast, mean Cu concentration in pre-monsoon (0.21 mg L −1 ) and post-monsoon (0.08 mg L −1 ) falls within the USEPA, EU and WHO criterion for water quality. However, measured concentrations are higher to those reported in other studies (Venugopal et al 2009). Mn concentration (0-7.8 mg L −1 )…”

“…Similarly, Zn concentration was also above USEPA criteria but lower to those of WHO guideline of drinking water quality. Zn concentration recorded in the current study was higher to those reported in other studies (Jaji et al 2007;Venugopal et al 2009;Zhou et al 2007). …”

“…Pb concentrations (0.03-2.38 mg L −1 ) were higher to the EU and WHO standard for drinking water and USEPA standards of surface water. Measured concentrations were also higher to those reported in Adyar River India (Venugopal et al 2009), and Ogun River Nigeria (Jaji et al 2007). …”

Geochemical Parameters of Water Quality of Karra River, Hetauda Industrial Area, Central Nepal

“…River water studies have received wide attention due to the need to understand the weathering, hydrological, seasonal, and anthropogenic factors which influences the water quality (Venugopal et al 2009). …”

Chemical composition of runoff water in Raipur city, central India

“…The urban runoff water quality greatly affects the surface and groundwater quality, fishing, animal and bird life, agriculture production, etc. in India (Chattopadhyay et al 2005;Mujumdar 2008;Rao and Mamatha 2004;Sargaonkar 2006;Solaraj et al 2010;Patel et al 2012;Venugopal et al 2009;Zafar and Alappat 2005). Water pollution is a very serious problem in India, which is the second most populous nation in the world.…”
