--- Quote from: nid404 on June 04, 2009, 07:25:36 am ---It's A cuz when sewage enters the river it promotes growth of algae and bacteria feed on them;use up a lot of oxygen. But as u go downstream most of the nutrients in the sewage r either used up or fed upon by bacteria......so the groeth of algae and number of bacteria decrease and this restores the level of oxygen.
Tell me if u didn't get it
