Abstract

This article focuses on the assessment of uranium concentration in groundwater of Davanagere district, Karnataka, India, and its associated radiological and chemical health risks. Groundwater samples from 75 locations revealed uranium levels ranging from 18.41 to 173.21 μg L⁻¹, with higher concentrations found in areas underlain by metamorphic, plutonic, and volcanic rocks, particularly in the Eastern Dharwar Craton region. Approximately 15.3% of samples exceeded the Atomic Energy Regulatory Board (AERB) limit of 60 μg L⁻¹, and 66.8% surpassed the World Health Organization (WHO) and United States Environmental Protection Agency (USEPA) guideline of 30 μg L⁻¹. The estimated annual effective ingestion dose varied up to 141.11 μSv y⁻¹, with some values exceeding WHO’s Individual Dose Criterion, and lifetime cancer risk (LCR) assessments indicated potential health concerns for a portion of the population. The study underscores the influence of local geology on uranium levels and recommends ongoing monitoring to manage public health risks.
