Appraisal of age-dependent geogenic radiation exposure and carcinogenic risks in the groundwater of Sevathur mine region, Pambar River basin, South India.

This study investigates groundwater uranium contamination and radiological risks in a part of Pambar River basin, South India, a region with significant geogenic radiation influenced by carbonatite rock formations. Uranium concentrations ranged from 5.8 to 240.

Health hazards from perchlorate enriched groundwater of a semi-arid river basin of south India and suggesting in-situ remediation through Managed Aquifer Recharge.

The present study was conducted to assess the groundwater quality and perchlorate contents in the pre- and post-monsoon groundwater samples along with its associated health concerns with suggesting in-situ remediation in semi-arid Arjunanadi River basin of south India. Most of the samples (86 in pre-monsoon and 84 in post-monsoon out of total 94) showed secondary salinity and secondary alkalinity, and the perchlorate showed positive relations with Na, K, SO, Cl, and NO contents. The main source of perchlorate could be fireworks manufacturing industries with 23 % of pre-monsoon (246.

Assessment of groundwater fluoride and human health effects in a hard rock province of south India: Implications from Pollution Index Model (PIM) and Geographical Information System (GIS) techniques.

This research examines whether the groundwater in the Sivakasi Region of South India is suitable for consumption, and assesses the possible health hazards for various age demographics including infants, children, teenagers, and adults. A total of 77 groundwater samples were gathered, covering a total area of 580 km and analyzed for major and minor ions. The hydrogen ion concentration (pH) of the samples indicates neutral to marginally alkaline.
