Why is water from an aquifer more likely to be cleaner than water from other sources?

• because pollutants are filtered by rock and soil deep within the Earth

• because it rises to the surface near the ocean

• because it receives water directly from precipitation

• because it forms where fresh water meets salt water

Water that flows downslope on Earth's surface may enter a stream, river, or lake though

• groundwater

• aquifer

• infiltration

• runoff
