GIS assists monitoring of heavy metals along Indian coast

The World Health Organisation has begun a project to monitor the level of heavy metals in 400 coastal water bodies in Tamil Nadu in India fearing the tsunami last year may have deposited these substances along the coast. The monitoring is taking place in the coastal water bodies such as wells and deep and shallow tube wells. The water bodies have been identified using GIS. Tests are being done every alternate month for heavy metals such as Cadmium, Lead and Titanium. The aim is to know whether tsunami has caused any damage to the quality of ground water bodies. The project begun seven-eight months back and would run for about one and half years from now. Four observations about the level of heavy metals have already been made in the project.
