Abstract: The current study was carried out for examining the heavy metal pollution profile of seven urban ponds in Chavara industrial area, south west coast of India. The study was conducted seasonally for a period of one year from January 2014 to December 2014. Results obtained from AAS analysis showed that toxic heavy metals such as copper (Cu), Manganese (Mn), zinc (Zn), Iron (Fe), lead (Pb), Cadmium (Cd), Nickel (Ni), Cobalt (Co), and Chromium (Cr) in the water samples were found to be higher than drinking water standards prescribed by WHO, BIS and FAO. This study is an attempt to compare the hydrological assessment of heavy metals in water of different ponds due to pollution from near industry-KMML, situates in Chavara, Kollam, India.
