Contaminants can impact natural resources, public health and the economy. Most enter the environment from industrial and commercial facilities; oil and chemical spills; non-point sources such as roads, parking lots, and storm drains; and wastewater treatment plants and sewage systems. Many hazardous waste sites and industrial facilities have been contaminated for decades and continue to impact the environment. NOAA acts as a trustee through many legislative authorities. As part of NOAA’s responsibilities as a natural resource trustee, NOS response and restoration experts evaluate and address contaminants in the coastal environment.
