Soundkeeper stated its mission as the protection and enhancement of the biological, physical, and chemical integrity of Long Island Sound and its watershed. To accomplish the organizations stated goals, Soundkeeper Inc. undertook activities in several program areas. In addition to the main program areas which include legal advocacy, monitoring and patrol of Long Island Sound and wetlands restoration, Soundkeeper operated five pump out vessels in western Long Island Sound to prevent sewage from being discharged overboard from vessel into the Sound. Soundkeeper pioneered new storm water pollution prevention by establishing a pilot program in Norwalk, CT. The "Filter Project" placed 254 storm drain filter inserts in catch basins designed to kill bacteria, and capture hydrocarbons and other pollutants.
