CWA Surface Water Quality Data

The Arizona Department of Environmental Quality (ADEQ) is seeking surface water quality data. The 2022 Clean Water Act (CWA) Assessment will use the data. This report is also known as Arizona’s Integrated 305(b) Assessment and 303(d) Listing Report. ADEQ uses monitoring data to assess whether lake and stream uses are protected by the CWA and in addition can be used for recreation, drinking, agriculture, wildlife and fish consumption. 

ADEQ encourages and welcomes data from all sources. These sources can include private citizens, businesses, public agencies, state as well as federal governmental agencies, and non-profit organizations.

Time Period

ADEQ requests surface water quality data collected for the period from July 1, 2012, to April 30, 2021 that has not previously been submitted to ADEQ. The deadline for submissions is April 30, 2021.
