Ch 13 Water Pollution Treatment
Your homework for this lesson is to read chapter 13 (Keller, 9ed) and assess your understanding of the key concepts, the meaning of the focus words, and the answers to questions to consider.
1: Key Learning Concepts:
Clean freshwater is essential for humans and healthy ecosystems. Increasing shortages and contamination of freshwater supplies are a key challenge facing humanity. At the end of this lesson, you should be able to:
Define water pollution and discuss some of the common water pollutants.
Discuss selected water pollution problems, including cultural eutrophication and acid mine drainage.
Describe point and nonpoint sources of water pollution and the difference between them.
Describe how groundwater becomes polluted and treatment methods for polluted water.
Discuss important issues related to water quality standards.
Know the principles of wastewater treatment associated with septic-tank sewage disposal and wastewater treatment plants.
Outline the processes related to wastewater renovation and wastewater treatment involving resource recovery.
Gain an appreciation for federal laws and regulations pertinent to water quality.
2: Focus Words:
Cultural eutrophication
Secondary treatment
Biochemical oxygen demand (BOD)
Point sources
Pollutant
Primary treatment
Acid mine drainage
Advanced treatment
Wastewater renovation and conservation cycle
Water pollution

3: Questions to Consider:
What is the principal cause of cultural eutrophication?
If MTBE (methyl tert-butyl ether) has such an impact on groundwater, why is it added to gasoline?
If sediment is from natural sources, why is it considered a water pollutant?
Saltwater intrusion results from
The level of decaying organic matter in water is indicated by what measure?
Which of the following would be considered a point source of pollution?
Nitrogen and __________ are usually responsible for cultural eutrophication.
