ABSTRACT
In considering water reuse, it is important to acknowledge that most tap water has had some contact with treated sewage. Wastewater treatment plants discharge into streams that feed rivers from which other cities pump water for drinking. By the time New Orleans’ residents drink the Mississippi, the water has been in and out of more than a dozen cities. More than 200 communities, including Las Vegas, discharge treated wastewater into the Colorado River’ which is used as a drinking water source for southern California. In these natural waterways, most contaminates le in the euent are diluted, biodegraded, and/or photodegraded. In addition, the drinking water treatment process removes anything le over [18].
