Which statement is true about average water use?

• A. Average water use depends on temperature, rainfall, cost, supply, and economic level.
• B. Water occurs in four forms.
• C. Surface water prior to treatment is called fresh water.
• D. The state must be notified about changes to public water systems.

Answer: (A)

Average water use is driven by a mix of climate, price, and supply factors that influence how much people and systems consume on a daily basis. Temperature affects how much outdoor and indoor water is needed—hot days drive more irrigation and cooling water, while milder weather reduces outdoor demand. Rainfall plays a big role too: more rain generally lowers outdoor irrigation needs, so average use goes down in wet periods. Cost matters because water price signals encourage conservation; higher prices tend to reduce per‑capita and per‑household usage. The available supply and reliability of that supply also shape use— if water is viewed as plentiful, usage can rise; if supply is uncertain or scarce, people and utilities conserve more. Economic level matters as well since wealthier communities often have larger homes, more landscaping, and more water-using appliances, which can raise average use. The other statements aren’t about how much water is used on average. Water occurs in forms that aren’t relevant to daily use patterns. Untreated surface water isn’t classified as “fresh water” in a way that dictates average use, and regulatory notification about changes to public water systems concerns compliance, not typical demand.
