Tank in Brazil
On 5th May 1983, a tanker collided with a chemical
storage tank. 500 m3 of carbon tetrachloride, chloroform, 1,2-dichloroethane
and 1.1.2-trichloroethane were released into the Pinheirinho and
Avecuia rivers (Brazil).
Pumping operations began with the deep waters near the spillage
area. In 5 days, 20 m3 of substances were recovered. Dredging operations
removed a layer of between 0.5 and 1 metre of mud from the bottom
of the lake. The decontamination system for the mud was made up
of two 50 m³ drains with walls at a 45° angle.
