Additional site remediation studies are being undertaken by national institutions, as desired by the Tamil Nadu Pollution Control Board (TNPCB) and the Court's Scientific Experts Committee (SEC) during the project review meeting in January 2010. IIT Delhi is revalidating the risk assessment study and site-specific clean-up standards; the National Botanical Research Institute, Lucknow, is studying the impact on trees and preservation of trees; and the Centre for Soil and Water Conservation Research and Training Institute, Ooty, is studying the impact on soil and soil erosion. Based on the above study findings, results of remediation trials and recommendations of the SEC, the TNPCB will take a final decision on the clean-up standards. Hindustan Unilever Ltd. will commence soil remediation work at the factory site once a decision on clean-up standards is taken and consent is given by TNPCB.
