AB  - Tanneries in an industrial area of Ranipet (India) manufactured sodium bi-chromate crystals and
chromium sulphate tanning powder during 1976-1996. Tamil Nadu Chromate and Chemicals (TCCL) factory
generated approximately 1,60,000 m ton of chromium waste which is dumped in the factory premises to a height
of 2-4 m of Hexavalent chromium Cr (6). Disposal of this waste face a threat to the people residing in around the
area for 40 years. Disposal of the chromium waste is the great problem to be addressed. It was observed that
the Hexavalent chromium contamination reached to a depth of 15 m in the upstream of the dyke and in the
downstream to a depth of 8-10 m. The migration of Hexavalent chromium is very slow with a ground water
velocity of 10 m/year. The sludge is mixed with the soil and the ground water being contaminated with
chromium. Because of this environmental effect we had taken initiative to make remediation onsite. As a
remedial measure an onsite Geo chemical fixation method may be adopted for decontamination of hexavalent
chromium.
