Few land uses generate more water pollution per acre than construction sites. Federal law requires that once the initial two- to four-week earth-moving phase ends on construction sites all exposed soil must be protected with a thick layer of straw mulch, grass or other erosion-stabilizing treatments. Compliance with this law is generally poor due to a lack of public awareness. This lack of awareness prevents construction regulatory agencies from gaining the public support key to achieving a high level of compliance. Volunteers participating in this project can assess compliance in their area. If compliance is low then publicizing their findings will be an important step towards improving local water quality.
