Memphis (UPI) Jan 14, 2008 Memphis officials are considering treating wastewater with small amounts of bleach to protect Mississippi River recreational users from E. coli infection. Until now, Tennessee state regulators have not required the city to disinfect its wastewater because it empties into the vast Mississippi River in a stretch where previously there was little recreation, The Memphis Commercial Appeal reported Sunday. But growing recreational activity on the river south of the Stiles Wastewater Treatment Facility -- including swimming and kayaking -- has led the Tennessee Department of Environment and Conservation to reconsider. A Memphis city study found nearly all E. coli could be eliminated from its wastewater by adding a small amount of bleach. The solution is not without hazards, however, the newspaper said. Chlorine-based disinfectants can cause trihalomethanes -- cancer-causing compounds -- to form, which could affect downstream drinking water.

![]() ![]() In order to increase productivity, forest practices have become more intense in recent decades. Forest fertilization increased by 800% in the southeastern United States from 1990 to 1999, and the total acreage fertilized in the Southeast exceeds the forest area fertilized in the rest of the world. This has generated concern that intensive forest practices, including fertilization, may negatively impact water quality in forest streams. |
