MUTAGENIC POTENTIALS OF POTABLE WATER FROM GROUND SOURCES

Abstract

Method: Four different types of samples were collected from four water treatment factories within Port Harcourt metropolis: raw water from borehole (1), water after sand and granular activated carbon filtration (2), water after reverse osmosis (3), and water after Ozone and UV treatment (4). These samples were subjected to mutagenicity test using two mutant strains of Salmonella typhimurium (TA 100 and TA 98) without S9 activation enzyme.
