Rao, V. Rao, K. Ranganathan, L. Surinaidu, J. Mahesh, G. Ramesh] Evaluation de la contamination de l'eau souterraine par un site de dépôt dangereux à Ranipet, Tamil Nadu, Inde Tanneries located in an industrial development area of Ranipet (India) manufactured chromate chemicals during 1976-1996. A large quantity of associated hazardous solid wastes has been stacked about 5-m high above ground level, spread over 3.5ha inside one of the factory premises. The study area receives an average annual rainfall of 1,100mm. The granitic formation in the northern part of Palar River catchment has high infiltration rates and has resulted in fast migration of the contamination to the water table. Chromium levels in the groundwater were found up to 275mg/l. The available hydrogeological, geophysical and groundwater quality data bases have been used to construct a groundwater flow and mass transport model for assessing the groundwater contamination and it has been calibrated for the next 30years. The migration has been found to be very slow, with a groundwater velocity of 10m/year. This is the first field-scale study of its kind in this industrial area. The findings are of relevance to addressing the groundwater pollution due to indiscriminate disposal practices of hazardous waste in areas located on the phreatic aquifer. Further, it has been reported that the untreated effluent discharge adjacent to the chromium dump site is most influential in the migration of contaminants.
