Runoff from construction sites often flows to storm drainage systems and ultimately is discharged into local rivers and streams. The runoff can contain:

SEDIMENT (soil, sand, etc.)
During a short period of time, construction sites can contribute more sediment to streams than can be deposited naturally during several decades. 

NUTRIENTS (nitrogen and phosphorous) 
These are of specific concern because they can cause significantly impaired water quality. 

OTHER POLLUTANTS
Solid and sanitary wastes, pesticides, oil and grease, concrete truck washout, construction chemicals, construction debris, and metals may be discharged and cause an impact on receiving waters.

Effective construction site pollution prevention can dramatically reduce pollute loading to stream ecosystems.
