Question

1 multiple choice 2 points which of these is a common strategy used to reduce water pollution under the clean water act? ignoring water pollution problems encouraging the release of more pollutants into water bodies requiring industries to treat wastewater before discharge promoting the dumping of waste into rivers 2 multiple choice 2 points runoff from urban streets, parking lots, and rooftops is a common example of: point source pollution nonpoint source pollution industrial pollution natural pollution 3 multiple choice 2 points what causes dead zones in the ocean? excessive nutrient runoff from land low water temperature abundant aquatic plants high oxygen levels

Explanation:

1. The Clean Water Act aims to protect and improve water quality. Requiring industries to treat wastewater before discharge helps reduce pollutants entering water bodies. Ignoring pollution, encouraging pollutant release, or promoting waste dumping are contrary to pollution - reduction goals.
2. Nonpoint source pollution comes from diffuse sources like urban runoff (from streets, parking lots, rooftops). Point source pollution has a single identifiable source (e.g., a pipe from a factory). Industrial pollution is a subset of point or non - point depending on the source. Natural pollution is from natural processes (e.g., volcanic ash in water), which urban runoff is not.
3. Excessive nutrient runoff (like from fertilizers) causes algal blooms. When algae die and decompose, oxygen is depleted, creating dead zones. Low water temperature, abundant aquatic plants (if not overgrown due to nutrients), and high oxygen levels do not cause dead zones.

Answer:

1. Requiring industries to treat wastewater before discharge
2. Nonpoint source pollution
3. Excessive nutrient runoff from land
