- The waste water from industrial, agricultural and domestic could reduce the quality of water if dispose direcly to the water body. Water quality can be assessed biologically using aquatic biota as a bio-indicator. The research took place at Singkil River on Mei to Juni 2012. There are five research stations has been monitored. Biological parameters that be calculated include diversity index, evenness index and biotic index. In general the biggest proportion of makrozoobentos community is Melanoides sp dan Anantome sp, plankton community is Gonatozygon sp from family Mesotaniaceae. Makrozoobentos individual abudance is around 64.815 ind/m2 - 457.407 ind/m2, plankton individual abundance is around 2.368 – 3.288 ind/l and biotic index is 8. Based on diversity index and biotic index approaches, pollution level and water quality of the Singkil River is categorized as unpolluted to moderat polluted.
