Uranium contamination in Delhi's groundwater has become a significant public health concern, with recent reports indicating that 13-15 percent of samples exceed safety limits, a rise from previous years. This places Delhi third nationwide for such contamination. The issue is particularly critical for communities relying on borewells and tankers, especially in low-income areas. While India adopted WHO's 30 parts per billion limit, some advocates argue for stricter international standards, highlighting the silent and slow-acting health impacts of uranium.
