Naturally-Occurring Radiation: 

Water Treatment Wastes

TENORM

Drinking water treatment wastes are thought to contain low concentrations of radium (Ra-226), comparable to those found in typical soils. However, some water supply systems, primarily those relying on groundwater sources, may generate wastes with much higher Ra-226 levels. Furthermore, some water treatment systems are more effective than others in removing naturally occurring radionuclides from the water.

Wastewater treatment wastes may contain both naturally-occurring radionuclides and radioactive material legally disposed into the sanitary sewage collection system under federal and state regulations.
