• 1888

• 530

• 280

• 3800

Point-source pollution is one that:

• can be found coming from many different places

• is from a specific singular location

Nonpoint source pollution is one that

• happens only once a year

• happens every several years

• is from unknown sources

• is from many places spread over a large area

Eutrophication results from the presence of which things in water:

• salts

• cyanide

• nutrient

• carbon dioxide
