Tracing Sewage Contamination in Urban Tropical Coastal Waters
Abstract: Most people give
less attention on sewage contamination in urban coastal waters. It is mainly
because sewage contamination in coastal waters mostly was reported not
detected. Using bio-indicator for detecting sewage contamination in urban
coastal waters has problems because of the environmental stress. To better understand
of sewage contamination in urban tropical coastal waters, 48 surface bottom
sediment and water samples of Semarang coastal waters were collected during East
monsoon (July 1997) and West monsoon (February 1998). Coprostanol, a fecal
sterol, had been analyzed to understand the sewage contamination in urban
tropical coastal waters. The analyses included: a) coprostanol contain, b)
sediment characteristics, and c) coliform bacteria. The results show that by
using coprostanol it was clearly defined that Semarang coastal waters was
contaminated by sewage, which by using bio-indicator, fecal coliform, could not
be detected.
