Env Sci 3B Human Impacts on Water & Air

Which of the following is NOT an example of point-source pollution

• oil that is escaping from a damaged tanker

• Water runoff from lots of residential lawns

• heavy metals that are leaching out of an underground mine

• untreated sewage that is accidentally released from a wastewater treatment plant

Thermal pollution has a harmful effect on aquatic environments because

• water has been circulated around power-plant generators

• it increases the number of disease-causing organisms in aquatic environments

• it reduces the amount of dissolved oxygen in aquatic environments

• it decreases the nutrient levels in aquatic environments
