Published in: Arizona Silver Belt on Wednesday, May 3, 2017

Notice Read the Following: The Arizona Department of Environmental Quality (ADEQ), in accordance with Section 303(d) of the Clean Water Act, has developed a Total Maximum Daily Load (TMDL) analysis for Pinto Creek located near Superior, Arizona.  ADEQ has determined that this stream is impaired for dissolved copper.

Watershed Name

Pinto Creek


A TMDL defines the total amount of a particular constituent or pollutant which can be introduced into a water body without causing an exceedance of state surface water quality standards.  The TMDL process enlists the participation of stakeholder groups and other interested parties to assist in identifying possible sources of pollution, to allocate loads of those pollutants in accordance with the objectives of the analysis, and to identify the most reasonable measures that should be implemented in order for the stream to achieve surface water quality standards.
