EEn.2.4 Evaluate how humans use water.
Clarifying objective:
EEn.2.3.2 Explain how ground water and surface water interact.
EEn.2.4.1 Evaluate human influences on freshwater availability.
EEn.2.4.2 Evaluate human influences on water quality in North Carolina’s river basins, wetlands and tidal environments.
EEn.2.3.2
• Illustrate the water cycle to explain the connection between groundwater and surface water, detailing how groundwater moves through the lithosphere. (Emphasize the processes of evaporation and infiltration in the conceptual diagram of the hydrologic cycle.)
• Explain river systems including NC river basins, aquifers, and watersheds.
• Explain how flood events might be affected by groundwater levels.
EEn.2.4.1
• Explain various water uses by humans and evaluate for benefits and consequences of use (ex. wells, aquifer depletion, dams and dam removal, agriculture, recreation).
• Explain consequences of aquifer depletion including subsidence and salt-water intrusion on the coast.
• Evaluate the effects of population growth on potable water resources. Infer future effects
• Explain how pollutants might flow through a watershed and affect inhabitants that share the same watershed.
EEn.2.4.2
• Evaluate issues of ground and surface water pollution, wetland and estuary degradation, and salt water intrusion.
• Analyze how drinking water and wastewater treatment systems impact quantity and quality of potable water.
• Evaluate water quality of NC streams (chemical, physical properties, biotic index).
• Analyze non-point source pollution and effects on water quality (sedimentation, stormwater runoff, naturally and human induced occurrences of arsenic in groundwater).
• Evaluate conservation measures to maximize quality and quantity of available freshwater resources.
EEn.2.1.4
• Conclude the best location for various types of development to reduce impacts by geohazards and protect property.
• Explain precautions that can be made to protect life from various geohazards and include meteorological hazards. Some examples include landslides, earthquakes, tsunamis, sinkholes, groundwater pollution, and flooding

Key Questions
1. Where does our drinking water come from?
2. Where does water go when I flush it down the toilet? 3. Where does water go when it flows down a storm drain? 4. What factors increase the risk of flooding? 5. What are the causes and consequences of groundwater depletion? 6. How do we know if our water is safe? 7. Why is water conservation important? What can we do to conserve water? 8. Why are wetlands important? |
Criteria for Success: "I will"
-Compare and contrast coastal plain and Piedmont sources of drinking water.
-Compare and contrast primary and secondary water treatment, and identify ways private citizens can help keep water clean. -Assess how land use impacts permeability, run-off, and the potential for flooding. -Discuss severe cases of groundwater depletion, such as the Ogallala Aquifer, San Joachim Valley, Houston, and others—why did they over pump? What happened as a result? -Use water quality data and table of “ideal” ranges to assess local water quality. -Calculate water footprint, and suggest ways to make it smaller. -Describe three important ecosystem services wetlands provide. |
