چکیده
Increase in urbanization and industrialization has posed a major problem of safe disposal of sewage and industrial effluents in different parts of country. Ahmedabad city had the highest number of composite textile mills in the country. In association, most of the SSIs and MSIs were established and they utilize large amount of water and discharge their effluents into the nearby Kharicut canal. The matter of pollution in Kharicut has been an important issue for the State Government and various agencies. The present study was conducted to investigate the water quality by analysing samples collected at various sites of Kharicut Canal passing through Vatva area and its vicinity in Ahmedabad city in months of February-March 2005. In date-wise study (study-A), there were changes in colour and odour at three sites on different dates. Site-III had maximum changes in most of chemical parameters studied compared to WHO and GPCB standards. A study at different sites on same day (Study-B) showed marked differences in water quality. Most of the samples were colourless and odourless. There was gradual increase in pH from site I towards site V. However, pH values were within permissible limit. Most of the changes were reported at site-IV and VI in terms of parameters like total hardness, calcium hardness, chlorinity and salinity. The residential areas of Vatva also showed higher amount of calcium and magnesium hardness, chlorinity and salinity compared to WHO and GPCB standards. There is need of more number of sampling and continuous monitoring to evaluate the pollution status.
