Assessment of quality of drinking water in Amasaman, Accra (Ghana)

Abstract

The physico-chemical and microbial quality attributes of untreated water samples from hand dug wells and treated water delivered by tankers (mobile services) were assessed to determine the susceptibility of Amasaman community to water borne diseases. The physico-chemical parameters of all the water sources for domestic use were within the World Health Organization (WHO) drinking water guidelines and Ghana Standards (GS), with the exception of turbidity and colour which showed higher values for the well waters. With respect to the micro-bial quality, the waters from the hand-dug wells and tanker services showed presence of both total and faecal coliforms, at levels higher than WHO and GS values of zero counts per 100 mL for drinking water. The poor microbial quality (presence of coliform bacteria) of all the water samples suggested susceptibility and exposure of the community to waterborne diseases on continuously drinking the available water.
