sewers carrying human waste
storm sewers
sewers carrying road and parking lot runoff
release of natural waters or a partially treated mixture of sewage and street runoff usually after heavy rains

9 steps causing hypoxia in LIS
1. excess nitrogen is sprayed on hundreds of residential lawns
2. rain brings nitrogen to rivers then to the sound
3.excess nitrogen in the water causes an algae bloom
4.the alage die in a short while and settle to the bottom of the water
5. bacteria decompose the dead alage using more and more dissolved oxygen as the bacteria multiplies
6.dissolved oxygen levels become very low
7.fish leave and other less mobile animals weaken and die
8. the animals that did from low oxygen levels dcompse
9 decomposers use more oxygen and the problem of low oxygen becomes worse
