Mercury and radioactive elements found in Savannah River bass

By  | 

(WRDW/WAGT) -- Plenty of people in the river region go fishing and keep their catch for dinner. But some fish have restrictions on how much you should eat because they could make you sick or even give you cancer.

This includes fish caught in the Savannah River between Thurmond Dam and Screven County. A study from Georgia Department of Natural Resources says you should only eat large mouth bass once a week if it comes from the Savannah River. That's because of mercury contamination.

There are currently no restrictions on catfish, but there is a restriction to eating sunfish only once a week for areas along the river in Screven County.

Mercury poisoning affects pregnant women and children the most so it's best these groups avoid eating bass from the river. Also, some fish in the river south of the Lock and Dam may also be contaminated with radioactive chemicals known to cause cancer.

Additional fish data on the Savannah River from the South Carolina Department of Health and Environmental Control show results that are totally different from Georgia DNR’s findings. We will compare the two studies tomorrow for the Savannah River and Clarks Hill Lake. ​
