Effect of water-guard on bacterial load in drinking water

Abstract

Water is the most important thing for the existing earth and also  known to serve as a route for transmission of water borne diseases worldwide most especially in the developing countries. The current study was initiated to evaluate the effect of water-guard in drinking water. Nutrient agar was used to isolate bacterial colonies from water-guard treated drinking water and untreated one. The result revealed that there was high difference in bacterial colonies among treated and untreated drinking water that untreated one contained 165,131 and 148 bacterial colonies from replication 1,2, and 3, respectively. In the other hand, treated water contained very low bacterial colonies that 4,6,5 from replication 1, 2,and 3 respectively.  Treating with water-guard is highly recommended for risk minimization that if the number of bacterial colony is high the opportunity to get pathogenic bacteria or water borne diseases can be also high.
