What health risks are associated with contaminated drinking water?

Contaminated drinking water poses significant health risks, primarily through exposure to waterborne diseases and potential long-term health issues. Water can become contaminated with various pathogens, chemicals, and heavy metals, leading to illnesses such as cholera, dysentery, and hepatitis A. These diseases are particularly dangerous in vulnerable populations, including children and the elderly. Moreover, long-term exposure to contaminated water, especially with pollutants like lead or arsenic, can result in chronic health issues, including developmental delays in children, cancer, and cardiovascular diseases.

The other options do not encompass the serious nature of the risks involved. Minor skin irritations or increased hair loss and skin aging might occur in limited contexts but are far outweighed by the severe consequences associated with waterborne diseases and long-term exposure to harmful contaminants. Furthermore, asserting that there are no risks at all ignores the reality of how water quality directly impacts public health.
