Is rain water the cleanest

Answer 1

Rainwater is generally considered clean and pure when it initially falls from the sky. However, as it travels through the atmosphere and collects impurities, it can become contaminated. Factors such as pollution, dust, and debris can affect the cleanliness of rainwater. Additionally, rainwater can pick up contaminants from rooftops, buildings, and other surfaces as it flows into collection systems. Thus, rainwater is not always guaranteed to be the cleanest source of water.
