Pasig river Pollution

Water Pollution

PollutionoAfter World War II, massive population growth, infrastructure construction, and the dispersal of economic activities to Manila's suburbs left the river neglected. The banks of the river attracted informal settlers and the remaining factories dumped their wastes into the river, making it effectively a huge sewer system. Industrialization had already polluted the river.oBy the 1970s, the river started to emanate offensive smells, and in the 1980s, fishing in the river was prohibited. By the 1990s, the Pasig River was considered biologically dead.
