Abstract
The present work aims to assess health risks associated with the exposure to uranium and heavy metals via potable groundwater in Uttarakhand state of India. For this purpose, potable groundwater samples were collected from the area and analyzed using LED fluorimetry and inductively coupled plasma mass spectrometry (ICPMS). The radiological (carcinogenic) and chemical (non-carcinogenic) risks associated with the exposure to uranium in majority of locations were observed below the safe limits suggested by WHO and USEPA. The levels of heavy metals present in potable groundwater were found well below the permissible limits recommended by WHO. An inter-comparison exercise between the results obtained with LED fluorimetry and ICPMS techniques was performed for the assurance of reliability and accuracy of results. The results were found in good agreement with each other.
