Microbial Contamination of Surface Water of High Density Industrial Zone, Estuarine Environment and Turtle Sanctuary in Davao City

Abstract

A bacteriological water analysis was used to analyze the microbial contamination of surface water of estuarine environment, turtle sanctuary and high density industrial zone in Davao City as a collaborative initiative to address the contamination issues of water quality and to a study conducted on the spatial distribution of selected heavy metals in surface sediments of surface water. Results obtained from this study, sought to provide baseline information on type of microorganisms and the level of contamination of surface water sources in the selected research locale. Further, this study intends to disseminate awareness on how affected communities within to improved water acquisition methods, purification and hygienic implication of using contaminated surface water sources and associated health risks with use. Lastly, this study can be used to strengthen and implement existing public policies in protecting the welfare of nearby communities by continuous surveillance and control of local pathogen infection linked to the use of contaminated surface water. The three sampling areas: estuarine environment, turtle sanctuary and high-density industrial zone were found to be contaminated as it has been determined to be a reservoir of a total of 42 gram-negative enteric bacterial isolates (p>0.05).
