Air pollution is caused by human introduction of chemicals, particulates, or biological materials into the atmosphere that harm humans or the environment. It causes deaths and respiratory disease. While major stationary sources contribute, the greatest source is actually mobile sources like automobiles. Smog results from large amounts of coal burning and is caused by smoke and sulfur dioxide. Acid rain damages buildings and statues and seriously harms trees. For nearly a billion years, the ozone layer protected life from ultraviolet rays but human activity like CFCs used in refrigerators and aerosols has contributed to holes in the ozone layer.
This document discusses various sources and effects of air and water pollution. It identifies seven main sources of air pollution, including exhaust from combustion engines, use of coal and fossil fuels, fertilizer dust, mining operations, chemical pesticides, power lines, and radioactive fallout.

13. Dredging Methods and Alternatives
1. Mechanically dredge
deposited sediment and
haul wet
2. Drain lake and dry
deposited sediment in
place before hauling
14. PRE-DREDGING:
An estimated
35,000 cubic yards
of sediment had
accumulated in
the lake, forming
islands and
reducing water
levels to less than
three feet in most
areas.
Lake Barton Example
19. North Park Lake Example Allegheny County, Pennsylvania
Dredging:
The lake was drained
and the sediment was
dried in-place.
