Abstract
([he study of the prevalence of Escherichia coli as indicator bacteria was carrie<I out in Sg. Sarawak, which involved four stations. The number of bacteria colony was measured in CFU/IOOml unit and relate to the water quality parameters such as pH, DO, FCC, TCC, and temperature. The presence of the E. coli and other bacteria is related with the human activities nearby the river. The drivers of the microbial contamination were studied based on community practiced of the households waste Indirectly, the environmental awareness among the community was measured based on participation in river activities, the opinion about river and daily practise that bring the effect to the river. From the study, the level of E. coli was highest at Satok Brigde station which was 90 CFU/ I OOml. This is due to the improper sewage disposal from residential area, low flow of the river, existence of municipal waste from local wet market, and domestic wastes. Meanwhile, the highest TCC and number of bacteria were identified at Waterfront Kuching stations which were 415 CFU/IOOml and 3372 CFU/IOOml, respectively. The common practise of the community that settle nearby the river was 18 % of the respondents involved in the questionnaires survey thrown domestic waste into the water, and 49 % of the respondents channelled the liquid waste directly to the river as well as the discharge of human waste into the river was 18% of the respondents. Lack of education and awareness campaigns on river pollution, has lead to low enviwnmental awareness about effective and correct practice to protect and conserve the river. The respondents opinions about river was 39.22 % of them mentioned the river was polluted with a Jot of waste found on the water surface.
