Hopes to fix the Santee Sioux Nation’s lack of clean drinking water faded as federal funding for a pipeline project is increasingly tangled in government turmoil. Tribal citizens are forced to drink bottled water to avoid the high levels of manganese in well water. On the Navajo Nation, dozens of people's water wells are contaminated with chemicals, like benzene, associated with the oil and gas drilling industry. There are many mysterious, uncapped wells that could be contributing to the problem. They are just two of the problems tribal citizens are having when it comes to accessing the most basic resource.
