Significant environmental impacts to coastal and ocean ecosystems occur via direct pollution from vessels, and as a vector for the invasion of non-indigenous species. Pollution from recreational, commercial, and military vessels emanates from a variety of sources, and include: gray water, bilgewater, blackwater (sewage), ballast water, anti-fouling paints (and their leachate), hazardous materials, and municipal and commercial garbage and other wastes.
