Beritabali.com reports that bio-indicator tests measuring life forms found in the Badung river that flows though Bali’s capital of Denpasar have resulted in a biotic reading of 2.7. A clean river would have a reading of 7, meaning that the Badung River in Bali can be officially considered as “very polluted.”
The water-quality tests were conducted by the Bali Center for Environmental Education (PPLH).
The coordinator of educational programs for the PPLH in Bali, Herni Frilia Hastuti, declared the Badung River has very polluted water quality after taking samples at five different locations.
At the subject five locations only bottom-feeding fish and mollusks were encountered. Such a finding indicates that the waters of the Badung River are unfit for human use – including even for secondary uses such as bathing, washing or toilet use.
According to Herni Frilia Hastuti, every bottom sample from the River uncovered large quantities of mollusks and bottom-feeding fish. Of some further concern is that fact that local populations are eating the fish living off the waste that collects on the bottom of the highly polluted river way.
She also confirmed that the pollution of the river starts from its source and extends to where it empties into the ocean. Heavily populated areas at the river's source are causing household pollution to be deposited into the river in substantial quantities.
