  • 1. 
    How did the study authors determine the toxicity of the sediment being tested?
    • A. 

      By identifying the substances in the sediment.

    • B. 

      By comparing the concentration of the contaminants in the sediment to known chemical benchmarks.

    • C. 

      By examining sediment-dwelling organisms.

    • D. 

      By testing fish, birds and animals in the area of the contamination.

    • E. 

      By analyzing the water in the river.

  • 2. 
    How did the authors conclude that the contamination in the WBGCR could injure humans?
    • A. 

      The toxicity of the sewer sludge pulled from the river exceeds safety benchmarks.

    • B. 

      Tests on birds living near the river revealed physical defects.

    • C. 

      Tests on fish caught in the river showed contamination.

    • D. 

      Reduced fish populations, degraded physical habitats, and alterations in the benthic vertebrate community are all evidence of contamination.

    • E. 

      Increased physical defects in fish, increased water staganation and increased populations of sediment dwelling organisms are all evidence of contamination.

  • 3. 
    Why couldn't the study authors develop a list of priorities for cleanup in the WBGCR?
    • A. 

      They did not have a complete list of the contaminants.

    • B. 

      The contaminants combined to make several unknown substances.

    • C. 

      Chemical benchmarks were not available for several of the identified substances.

    • D. 

      Only a limited area of the WBGCR was contaminated.

    • E. 

      The study funding was too limited to permit exhaustive testing of the substance.

  • 4. 
    What does the location of the highest concentrations of contaminated sediment suggest?
    • A. 

      The injury to the sediment is greatest in these locations.

    • B. 

      The most highly contaminated sediment is close to the source of the contamination.

    • C. 

      The turbidity of the water causes contaminants to congregate in certain parts of the river.

    • D. 

      People should be warned about fishing in these parts of the river.

    • E. 

      The most precise results of the levels of contaminants can be found in these locations.

  • 5. 
    Based upon the list of contaminants, what process is likely to have been responsible for the contamination?
    • A. 

      Dumping from ships in the river.

    • B. 

      Rainwater runoff from the surface streets.

    • C. 

      Airborne pollution that settled in the river.

    • D. 

      The contamination occurred naturally.

    • E. 

      Untreated manufacturing waste directly dumped into the water.
