Which statement is true regarding well water compared to rainwater?

Rainwater can be contaminated with pollutants due to a variety of factors such as environmental conditions, air quality, and collection methods. When rain falls, it can pick up particles from the atmosphere, including dust, pollutants, and chemicals. If rainwater is captured in storage systems, it can also become contaminated by the materials used in those systems or by biological contamination from animals or debris.

In contrast to well water, which generally comes from underground aquifers and can be tested for purity, rainwater is more susceptible to varying quality depending on its collection and the environment it passes through. Understanding the potential for contamination in rainwater is crucial for anyone considering its use for drinking, irrigation, or other purposes. This awareness emphasizes the need for proper filtration and treatment if rainwater is to be utilized safely.
