Storm Water Management

Stormwater discharges are generated by runoff from land and impervious areas such as paved streets, parking lots, and building rooftops during rainfall and snow events that often contain pollutants in quantities that could adversely affect water quality. Most stormwater discharges are considered point sources and require coverage by an EPA NPDES permit (see link below). The primary method to control stormwater discharges is through the use of best management practices.

Nonpoint Source Pollution

Florida's surface and ground water resources are extremely vulnerable. This is partially the result of the state's sandy, porous soils, geology and abundant rainfall in combination with rapid growth. The destructive effect of unplanned growth was seen as early as the 1930s when Southeast Florida's coastal water supply was threatened by saltwater intrusion. Extensive destruction of wetlands, bulldozing of beach and dune systems, over-development and poor land management practices have all led to the degradation of the state's waterbodies.

Industrial discharge, runoff from agriculture, silviculture and various types of animal husbandry contribute to pollution of the state's waters. Additionally, the state's growing population increases the problem of pollution associated with urban development and aging stormwater infrastructure.

Nonpoint source pollution is caused by stormwater runoff. Water flowing over, the land, during and immediately following a rainstorm is termed stormwater runoff. Stormwater runoff carries fertilizers, pesticides, soil, heavy metals, oils, grease, pathogens, debris and any other materials that accumulate on the land between rains into a receiving waterbody. The receiving waterbody in Florida's diverse water system could be a lake, river, estuary, or the groundwater system, all of which may ultimately drain into the coastal waters of the state.
