ADEQ Lifts Fish Consumption Advisory for Gila River and Tributaries

From the Arizona Department of Environmental Quality:

PHOENIX (September 30, 2015) – The Arizona Department of Environmental Quality (ADEQ) announced today that it has lifted the consumption advisory for fish caught in the Gila River and its tributaries within and downstream of the Phoenix metropolitan area – this includes 100 miles of streams and 286 acres of lakes. Fish caught from these waters are no longer unsafe to eat due to banned pesticides (DDT, chlordane or toxaphene).

“This is the first time ADEQ has lifted a fish consumption advisory,” said ADEQ Water Quality Division Director Trevor Baggiore. “Fish tested by ADEQ and the U.S. Fish and Wildlife Service show that banned pesticides no longer pose a health risk in the Gila River and its tributaries.”

Lifting this advisory, which has been in place for 24 years, is credited to the cessation of the use of the pesticides in the 1970s, 1980s and 1990s. Detailed information about the delisting of the Gila River and its tributaries can be found at:

ADEQ and the U.S. Fish and Wildlife Service tested 67 fish tissue samples from 8 different fish species in the Gila River and several of its tributaries west of Phoenix during 2011 and 2012. Fish tissue data demonstrated banned pesticide levels (DDT, toxaphene and chlordane) dropped from more than 160 times higher than the threshold levels designed to protect human health in the 1990’s to 16 times lower than these thresholds in 2011 and 2012.

On March 10, 2015, ADEQ requested that the U.S. Environmental Protection Agency (EPA) remove the Gila River and its tributaries from Arizona’s Impaired Waters List, which EPA approved August 7, 2015. Each water body removed from the list also had a fish consumption advisory in effect. ADEQ has lifted the fish consumption advisory for the following waterbodies:
