Factors dictating number and diversity of organisms
Excess nutrients enter water ways and cause overgrowth of plants that block sunlight and deplete oxygen
Eutrophication
Areas where life cannot exist due to the lack of oxygen
Dead zone
Pollution from an easily identifiable source
Point Source
Pollution that is an accumulation of many smaller sources
Non-point Source
Power Pool Limit
When the water level is too low to be able to generate power
Dead Pool Limit
When the water level is too low to feed the river
NYC’s drinking water source
Catskills
Binghamton’s drinking water source
Rockbottom Dam
Vestal’s drinking water source
Wells along the southern bank of the Susquehanna River
U.S.’s largest source of water
Groundwater and surface water
Chemicals are added to untreated water
Coagulation
Water and chemicals are mixed
Flocculation
Big particles settle and are removed
Sedimentation
Dissolved solids, germs, and odors are removed
Filtration
Chlorine and other chemicals kill remaining parasites
Disinfection
Water is pumped up to regulated pressure and is then distributed to consumers
Use of water towers
Sinking of land due to depleting of groundwater
Land Subsidence
