Spills that involve materials such as fuels (oil, diesel, or gasoline), paint, or other chemicals can be particularly harmful to the environment and residents. Materials can enter the natural environment:
- into local water bodies via storm sewers and ditches;
- directly to the earth or water bodies;
- into buildings and water treatment facilities via sewer laterals, mains and foundation drains; and,
- into the air via exhausts, ventilation systems, and chimneys.
