SOME TRACE ELEMENTS INVESTIGATION IN GROUNDWATER AROUND INDUSTRIAL BELT OF ROPAR BLOCK, RUPNAGAR DISTRICT, PUNJAB, INDIA
This paper deals with short review and the determination of five heavy metals viz. Fe, Hg, Pb, As and Cd in the groundwater of Ropar Block of Rupnagar District, Punjab which is also the industrial belt of the district. All activities carried out on the groundwater whether associated with urban, industrial or agricultural activities have impact on groundwater resources. Large scale concentrated source of pollutants such as industrial discharge and subsurface injection of chemicals and hazardous substances are obvious source of groundwater pollutants. The samples were collected from 15 locations from tubewells and handpumps at varying depths around the industrial belt. The analysis was done with the help of Atomic Absorption Spectrophotometer (AAS). Results obtained are compared with safe limits in ppm for heavy metals laid down by WHO (1993). The investigations reveal that most of the study area is highly contaminated due to the presence of Iron which has rendered nearly 95% of the water samples tested, non potable.
