Tap water is generally safe to drink, particularly if sourced from municipal supplies, although contamination can occur after events like flooding. The safety of well water depends on regular testing for contaminants, especially lead from old pipes. Concerns have been raised about disinfection byproducts, particularly from chloramines, which may produce harmful toxins linked to health risks such as bladder cancer. Recent studies have identified new iodoacid byproducts in chloraminated water, raising questions about their toxicity and the need for further research. Overall, while tap water safety varies by location and source, ongoing monitoring and research are essential for public health.
