The most common nonpoint pollutants are sediment and nutrients. These contaminants wash into water bodies from lawns, roads, construction sites, and other areas of disturbance. Runoff pollutants include fertilizers, pesticides, pathogens (bacteria and viruses), salts, oil, grease, toxic chemicals, and heavy metals. Beach closures, destroyed habitat, unsafe drinking water, fish kills, and many other severe environmental, economic, and human health problems result from these widespread pollutants. Each year, polluted runoff threatens community vitality. Restoration and protection of coastal resources cost millions.
