1. Solution
1.1. Reduce phosphate in lake by 40%
1.1.1. Reduce amount of phosphate running into lakes
1.1.1.1. better run off system
1.1.2. algal blooms spread
1.1.2.1. prevent spread of algal blooms by preventing the production of algal bloom in first place
1.2. equip water treatment plants with proper detoxifying technology
2. Impact
2.1. increase government spending
2.1.1. government devote 12 million to algal bloom solution for Ohio
2.2. disrupt ecosystem
2.3. contaminate town drinking water
2.3.1. Most Dense Bloom near intake of city's water plant
2.3.1.1. Microcyctin level three times over WHO standard for drinking water.
3. Causes
3.1. Chemicals encourage cyanobacteria growth in lake
3.1.1. the chemicals came from
3.1.1.1. Fertilizer run off
3.1.1.1.1. run off mostly caused by the increase of storms
3.1.2. Cyanobacteria produces microcystin
3.1.2.1. microcystin is a form of potent toxin
3.1.3. chemicals include potassium, phosphate, nitrogen etc.
4. Duration
4.1. last for long time
4.1.1. spreads to different areas over long time
4.1.1.1. reach peak population in a few months
5. climate change
5.1. leads to more storms
5.1.1. cause more run off containing chemicals which encourages cyanobacteria growth
