Question

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

Explanation:

Surface water is exposed to the environment and can easily pick up contaminants like chemicals, pathogens from runoff, sewage, and industrial waste, making it a less - suitable primary drinking water source without proper treatment. Evaporation is not the main concern for using it as drinking water, and population proximity is not related to its quality as a drinking water source.

Answer:

because surface waters are easily contaminated
