1. Ch. 12.3 Water Sustainability through Science and Technology

2. Connection between Land and Water ongoing research and technology is offering solutions to many of our water system problems – example: repairing riparian zones along rivers these solutions, however, must always be assessed in terms of how it affects the environment and society

3. Sustainability Solutions Using Bioremediation bioremediation – technique of using living organisms to clean up contamination in land and on water phytoremediation – the technique of using plants as environmental clean-up remedies – a subset of bioremediation

4. Sustainability Solutions Using Bioremediation bacteria are the microorganisms most often used to clean up contamination in our water systems – oil companies use bacteria to clean up petroleum spills – some types of bacteria use the petroleum chemicals as food, breaking down these chemicals into natural substances (such as carbon dioxide gas, a type of alcohol, and water)

5. Water Supply Solutions Using Desalination Technology desalination – process of removing salt from water – used to turn ocean water into drinking water – does have some drawbacks the waste water from the desalination plant contains a heavy concentration of salt this waste water can be toxic even to saltwater organisms other chemicals that are toxic to marine life are also found in this waste water
