Water is always found pure in nature.

Water is always found pure in nature.

• A. TRUE
• B. FALSE
• C. ONLY IN MOUNTAINS
• D. ALWAYS CLEAN

Answer: (B)

The main idea here is that natural water is not inherently pure. In nature, water interacts with rocks, soils, and organic matter, dissolving minerals such as calcium, magnesium, iron, and others, which changes its chemistry and taste. It also carries microorganisms and organic compounds from decaying material. Even rain can collect pollutants from the air before it reaches the ground. Because of these factors, water from lakes, rivers, streams, and groundwater typically contains impurities and cannot be assumed to be pure. From a water-treatment perspective, this is why sources must be treated to remove contaminants and pathogens to make the water safe to drink. That’s why the statement that water is always found pure is not correct. It’s not restricted to mountains, and it isn’t always clean—contaminants can be present in many environments.
