Non-point Source Pollution

Non-point source pollution (NPS) does not have a single point of origin; it is the cumulative result of our everyday personal actions and land use policies.

Types of NPS include: pathogens, nutrients, sediment, and debris

Low Impact Development

When we develop land, we can do so in a way that minimizes our impact. Low Impact Development or LID is a design principle that strives to maximize the amount of pervious surfaces and to imitate nature whenever possible. LID might include something as simple as a rain garden, a compost filter berm, or a constructed wetland. Here you can find an extensive listing of best management practices (BMPs) http://www.urban-nature.org/landuse/low_impact_development.htm

MS4 Permits

Polluted stormwater runoff is commonly transported through Municipal Separate Storm Sewer Systems (MS4s), from which it is often discharged untreated into local waterbodies. To prevent harmful pollutants from being washed or dumped into an MS4, operators must obtain a NPDES permit and develop a stormwater management program.
