ADEQ issues fish consumption advisory for Bartlett Lake


NORTH VALLEY – The Arizona Department of Environmental Quality, in association with the Arizona Game and Fish Department, has issued a fish consumption advisory recommending that people limit consumption of channel catfish and largemouth bass caught from Bartlett Lake in Maricopa County. ADEQ is issuing this advisory because recent fish tissue samples from Bartlett Lake contained elevated levels of mercury.

ADEQ recommends that adults limit consumption of channel catfish and largemouth bass to 2.4 ounces (uncooked weight) per week and children 12 years of age and under limit consumption to two ounces per month (uncooked weight).

This advisory does not limit the use of this waterbody for fishing, bird watching, swimming, or other recreational uses. In general, the level of contaminants in fish is several folds higher than levels found in water.

Any health risks associated with eating fish from this advisory area are based on long term consumption and are not representative of risk from eating fish occasionally.

According to the ADEQ Fish Consumption Advisory Fact Sheet, ADEQ is currently working on this issue through “data collection, analysis, and research to determine mercury sources in Arizona and develop feasible mitigation and remediation measures.”
