1. Point & Non-Point Source Water Pollution
All right who did it this time?

2. Definition & Types Point source – one identifiable source of pollution
Factory dumping sewage
Dumping oil into ground water
Non-Point Source – can’t be traced to a single source
Two or more farmers using same pesticides
Contaminated storm water

3. Location Point Non-Point Alaska – Exxon Valdez oil spill
Louisiana – BP oil spill
Non-Point
Mississippi Delta
San Francisco Bay
Chesapeake Bay

4. Pollution Causes Point Source Non-Point
Not disposing chemicals properly
Sewage
Non-Point
Tilling
Storm water
Boating

5. Environmental Consequences
Point
Chemicals get into groundwater
Oil stays in sand for a long time
Oil goes down 4% every year (Exxon)
Arctic habitats take years to recover
Non-Point
Tilling takes away top soil
Sediment runoff affects water quality
Fertilizer run of effects biodiversity

6. Pollution Conservation Efforts
Dispose of chemicals properly
Direct roof runoff to a grassed area or a rain collector
Collect litter and animal waste before they wash into a storm drain
Fertilize lawns and gardens according to soil test results
Watch for soil erosion, replace with sod to protect the eroded site

7. Cost BP fined 40 million dollars – for clean up efforts
5.5 million foot boom cost 850 million dollars
8.2 billion dollars to clean up water and debris after Katrina
$150 for 100 square feet of sod (includes installation)
$115 for a 50 gallon bin rain collector

8. Applicable Legislation
Clean Water Act
Protects water quality
Safe Drinking Water Act
Protects water quality of drinking water
Coastal Zone Management Act
Protects coastal waters and was added to focus on non-point source water pollution
Federal Insecticide, Fungicide, and Rodenticide Act
Requires farmers to register for their pesticides
Public trust Doctrine
Mandates that the government are stewards of common property such as water

9. Extra Facts Exxon paid half a billion dollars for damage in Alaska.
Factories and sewage treatment plants are two common types of point source water pollution.
The biggest oil spill ever was in Kuwait during the Gulf War.
The worst spot for sediment buildup
is at a delta or bay.
Citarum River in West Java, Indonesia
is one of the worst polluted rivers
