Water Resources - Complete Interactive Lesson

Part 1: Core Concepts

💧 Water Resources

Part 1 of 7 — Freshwater Supply, Use, and Pollution


Global Water Distribution

Water SourcePercentage of TotalAvailability
Oceans (saltwater)97.5%Not directly usable
Ice caps/glaciers1.7%Locked up; melting due to climate change
Groundwater0.76%Major freshwater source; aquifers
Surface water (lakes, rivers)0.01%Most accessible; heavily used
Atmosphere/soil moisture0.04%Part of water cycle

🔑 Only ~0.77% of all water on Earth is accessible fresh water (groundwater + surface water). This makes freshwater conservation critical.


Water Use by Sector

SectorGlobal Water UseExamples
Agriculture~70%Irrigation of crops, livestock
Industry~20%Manufacturing, cooling, mining
Domestic~10%Drinking, sanitation, cooking

Key Groundwater Terms

TermDefinition
AquiferUnderground layer of permeable rock holding water
Water tableTop surface of the saturated zone
Recharge zoneArea where water infiltrates to replenish aquifer
Cone of depressionLowering of water table around a pumping well
Ogallala AquiferLargest aquifer in US (Great Plains); being depleted faster than recharged

Non-point sourceDiffuse, widespreadAgricultural runoff, urban stormwater, atmospheric deposition

Major Water Pollutants

PollutantSourceImpact
Nutrients (N, P)Fertilizer, sewageEutrophication, algal blooms, dead zones
PathogensSewage, animal wasteCholera, typhoid, dysentery
SedimentErosion, constructionReduces water clarity; smothers habitats
Thermal pollutionPower plant cooling waterReduces dissolved oxygen; harms aquatic life
Heavy metalsMining, industryMercury, lead — bioaccumulate in food chains
Endocrine disruptorsPesticides, plastics, pharmaceuticalsInterfere with hormone systems in wildlife

Water Treatment

MethodPurposeLevel
Primary treatmentPhysical removal (screens, settling)Removes solids
Secondary treatmentBiological breakdown by bacteriaRemoves organic matter
Tertiary treatmentChemical/advanced treatmentRemoves nutrients, chemicals, pathogens

Applied Recall ✍️

  1. Pollution from a single identifiable location (like a factory pipe) is called _______ source pollution.

  2. Agriculture uses approximately _______% of global freshwater.

  3. An underground layer of permeable rock that holds water is called an _______.

Classify the Pollution 🔍

AP Exam Strategy: Water Resources

  • Point vs non-point source pollution is tested almost every year — know examples of each
  • Know the three levels of water treatment and what each removes
  • Groundwater depletion (especially Ogallala Aquifer) is a common FRQ topic
  • Understand cone of depression and how over-pumping affects water tables
  • Water scarcity affects 2+ billion people — know the connection to agriculture, population growth, and climate change
