Point & Non-Point Source Water Pollution

All right who did it this time?

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

Definition & Types

Point Alaska – Exxon Valdez oil spill Louisiana – BP oil spill

Non-Point Mississippi Delta San Francisco Bay Chesapeake Bay

Location

Point Source Not disposing chemicals properly Sewage

Non-Point Tilling Storm water Boating

Pollution Causes

Point Chemicals get into groundwater Oil stays in sand for a long time Oil goes down 4% every year (Exxon) Arctic habitats take 20-30 years to recover

Non-Point Tilling takes away top soil Sediment runoff affects water quality Fertilizer run of effects biodiversity

Environmental Consequences

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

Pollution Conservation Efforts

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

Cost

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

Applicable Legislation

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
