The "2010 Woodlawn Beach Sanitary Survey Report" completed by the New York State Office of Parks, Recreation, and Historic Preservation notes several potential bacteria sources which may affect the beach, including sewage overflows, stormwater outfalls, urban runoff, contaminated stream drainage, algae and leafy debris.[citation needed] Woodlawn Beach was identified by the Natural Resources Defense Council as the third most polluted swimming beach in New York State after failing 32% of water sample tests in 2011.[8]
