PUBLIC NOTICE | TMDL Analysis for Three Reaches of Queen Creek, Arnett Creek and Two Unnamed Drainages

Public Notice No. 17-10

Published in: Superior Sun on Wednesday, Sept. 27, 2017

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 three reaches of Queen Creek located near Superior, Ariz. TMDL’s have also been developed for Arnett Creek and two unnamed drainages. ADEQ has determined through sample collection and data analysis that the six separate stream reaches are impaired for dissolved copper.


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.
