Fish faring better than expected near TVA coal ash
spill
June 10
While fish living in the Emory River near where 5.4 million yards of
coal ash spilled from failed Tennessee Valley Authority containment
ponds have ingested small amounts of pollutants, overall the fish are
faring better than expected, researchers say.
Researchers with the Oak Ridge National Laboratory in Oak Ridge, Tenn.
have been collecting and testing fish near the site of the Dec. 2008
spill and also in the Emory River’s downriver waters. Fish, including
bluegill, largemouth bass, channel catfish, white crappie and gizzard
shad, have been monitored in the area since February 2009. Scientists
have found that while there are small amounts of contaminants like
arsenic and selenium in the fish, overall the fish are considered to be
healthy.
"We are looking to see if there has been an effect on overall fish
health and reproductive condition, and so far, such effects have not
been evident," said Mark Peterson, leader of ORNL Environmental Sciences
Division´s Ecological Assessment Team and the Aquatic Ecology
Laboratory.
Further testing will be required, scientists said. According to the
report, contaminants like selenium can increase over time in the food
chain. The second year of monitoring will prove important, researches
said.
