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

• it is where fresh and salt water meet

• it receives water directly from precipitation

• it rises to the surface near the ocean

• pollutants are filtered by rock and soil deep within Earth

Which would indicate the water in a lake is not safe for drinking?

• many varieties of fish in the lake

• high dissolved-oxygen levels in the lake

• cold water temperature of the lake

• high turbidity levels in the lake
