An accidental spill that sent 300 gallons of bleach into a storm drain last week appears to have caused a fish kill in a tributary of Rocky Creek, according to the Augusta Utilities Department.
An initial investigation of the March 15 accident yielded no evidence of damage to the ditch, which crosses Georgia Highway 56 and empties into Rocky Creek.
Department officials who conducted a follow-up survey, however, found three dead fish Tuesday and notified Georgia’s Department of Natural Resources, said Allen Saxon, the department’s assistant director for facility operations.
State biologists who conducted a more extensive assessment recovered about 300 dead fish, Saxon said.
The spill occurred at the department’s Peach Orchard Road office when a pump failed to turn off after loading 12.5 percent bleach solution from a large tank into a smaller one.
Cleanup crews added a dechlorination agent to the storm drain and flushed the area with water to push the chemical through the system.
