Question

why is using surface water as a primary drinking water source problematic? because not many people live near surface water because surface water evaporates too easily because surface waters are easily contaminated

Explanation:

Surface water is in contact with the environment, making it prone to contamination from various sources like industrial waste, agricultural runoff, and sewage. This contamination can introduce harmful substances such as bacteria, viruses, heavy metals, and chemicals. In contrast, the first option is incorrect as many people do live near surface water sources (e.g., rivers, lakes). The second option about evaporation is not the main reason for it being a problematic primary drinking water source compared to contamination risks.

Answer:

because surface waters are easily contaminated
