Stormwater and the Construction Industry
Polluted stormwater from construction sites often flows to municipal storm structures and ultimately is discharged into local rivers and streams. Sediment is usually the main pollutant of concern originating from construction sites. Sediment runoff rates from construction sites are typically 10 to 20 times greater than those of agricultural lands, and 1,000 to 2,000 times greater than those of forest lands. During a short period of time, construction sites can contribute more sediment to streams than can be deposited naturally during several decades. The resulting siltation, and the contribution of other pollutants from construction sites, can cause physical, chemical, and biological harm to rivers and lakes and the aquatic habitats that they support.
The Town of East Lyme supports the use of Best Management Practices (BMP’s) at construction sites in order to control stormwater runoff and the discharge of pollutants into local waterbodies. The Stormwater and the Construction Industry poster that is featured below was created & made available by the Environmental Protection Agency. Additional information in regards to soil erosion and sediment control measures and copies of the Stormwater and Construction Industry poster are available the East Lyme Department of Public Works.
