New Delhi, Sep 13: While rainwater has long been considered pure and natural, health experts caution that drinking it directly may pose hidden health risks if not treated properly.
According to environmental scientists, rainwater can pick up dust, pollutants, and microorganisms as it falls through the atmosphere or when it comes into contact with rooftops and storage containers. This may lead to contamination by bacteria, parasites, or even heavy metals.
“Rainwater is not inherently harmful, but it is not sterile. Without filtration or boiling, consuming it could expose people to waterborne illnesses,” said Dr. Rakesh Sharma, a public health expert.
Experts suggest that harvested rainwater can be made safe for drinking through proper filtration systems, boiling, or ultraviolet purification. In rural areas, where rainwater harvesting is common, health authorities stress awareness about safe storage and treatment.
They add that while rainwater is excellent for irrigation, washing, and household use, it should be carefully treated before being consumed.
