Answer to Question 1

The urban environment pollutes our water supply from sewage disposal systems, chemical runoff, roadway runoff,
surface runoff, and seepage from municipal landfills



Answer to Question 2

Certain macroinvertebrates cannot survive in polluted water. Other species thrive in polluted water. If you sample
the macroinvertebrates in a body of water and find mostly pollution-intolerant species, the water is probably pretty
clean. If only pollution-tolerant species are present, the water is likely very polluted.
