Item RELATIONSHIP BETWEEN CHLORINE RESIDUE AND BACTERIOLOGICAL QUALITY OF PUBLIC TAP WATER SUPPLY IN ILORIN, NIGERIA(Department of Geography and Environmental Management, University of Ilorin, Nigeria, 2013-12) Kayode Ademola, Iroye; Lawal, F.O.The study examined the relationship between chlorine residue and bacteriological qualify of top water in Ilorin. Twenty six water samples were collected from public tops at equidistance position of 500m along three road axis away from treatment plants using sterilized 50cl capacity plastic bottles. The samples were subsequently analysed at both Chemistry and Microbiology Laboratories of University of Ilorin following the standard procedure on drinking water. Of all the five water quality parameters examined in the study, only chloride level conforms to WHO (2008) standard on drinking water. Correlation analysis carried out revealed a strong negative relationship (r=-0.86) between free chlorine residue and fecal coliform count. The poor quality of pipe born water supply in the study area can be linked to inadequate chlorination, ageing infrastructure, unwholesome workmanship by plumbers and poor maintenance culture on the part of consumers authority concerned. The study thus put forward a number of recommendations towards improving the quality of water piped to the people.
