water
pollution
Industry
Agriculture
Municipal
there are three main sources of water pollution
Agriculture
Chemicals applied to farmlands wash in to streams, ponds, lakes or oceans
- Chemicals used for farms include: fertilizers and pesticides
- Excess chemicals can be picked up by rainwater
- Farms can produce millions of gallons of waste which often times get stored in huge lagoons
- Dissolved fertilizer can lead to plant and algae growth, which can lead to dead zones in the ocean
Fertilizer
Algal blooms
