NOTE: The data provided in this report differs slightly from the information provided in the New York State Department of Environmental Conservation (NYSDEC) 2008 303(d) list. One example is a discrepancy between the number of waterbody-impairment combinations in EPA's database/web site and the NYSDEC web site, which is due to NYSDEC not including approximately twenty waters that are listed for "other toxics" and other causes. The NYSDEC 2008 303(d) list is available at http://www.dec.ny.gov/chemical/23852.html
