Do you fish in the Cahaba? Here’s what you need to know about where fish is unsafe to eat in 2020.
Three of these advisories occurred in the Cahaba River, and all of these advisories were due to mercury, an airborne pollutant caused by the burning of fossil fuels, as is done by coal-fired power plants, and the burning of waste.
Fish consumption advisories for the Cahaba River have increased in recent years. In 2016, none of the Cahaba sampling locations detected mercury problems. In the 2018 and 2019 Fish Consumption Advisories, THREE of FOUR sampling locations detected enough mercury to warrant limitations on consumption.
