Arizona's final 2004 Integrated 305(b) Assessment and 303(d) Listing Report has been revised to include changes made by the US Environmental Protection Agency (EPA). ADEQ's report was submitted to EPA in 2004 for approval of the 303(d) list of impaired waters. EPA made the decision to add 19 surface waters, and eight additional pollutants on waters already listed, to Arizona's list. Therefore, all corresponding tables, maps and assessment statistics have been changed to reflect these additions.
