Water Systems

1.1

• Water distribution & quality
• Waves, tides & erosion
• Continental drainage
• Water & climate
• Diversity/population in water systems
• Humans & impacts

1.2

• Water quality = water vs what else is there
• Testing - clarity, chlorine, hardness, organisms, ph, dissolved O2, turbidity, solids/dissolved and not.

Distillation vs Reverse Osmosis

• Home demo of distillation
• Reverse Osmosis

To Recap

Distribution

• A small percentage of water is fresh. A smaller percentage is available. What determines if it’s potable?

Testing

• Colour
• Turbidity
• Toxins
• Bacteria count
• Hardness
• Solids
• Dissolved solids

In the dirty 30s, streams and sloughs dried up. Ignorance led to top soil being blown away. As the climate resets, how we adapt will define us.
