Tribes in the American southwest have made great strides in their efforts to monitor and control nonpoint source (NPS) pollution on reservation lands. Many of these tribes’ projects were recently highlighted in this publication. The document describes how the Indian tribes have used Clean Water Act Section 106 funds for water quality monitoring, thus enabling them to develop NPS pollution runoff control and management programs that ultimately improved environmental quality.
The document describes the long-term results of water quality monitoring from the NPS management programs and other management efforts by 12 Tribes in California, Nevada, and Arizona. Thanks to EPA and the other federal agencies that offer training and environmental program development and project support, increasing numbers of tribes are managing comprehensive water quality programs to protect, improve, and enhance natural resources for the benefit of all Tribal members.
