/*%\ EPA's BEACH Report: New York 2010 Swimming Season ***1 PBO^ May 2011 Introduction The BEACIT Act of 2000 requires that coastal and Great Lakes states and territories report to EPA on beach monitoring and notification data for their coastal recreation waters. The BEACH Act defines coastal recreation waters as the Great Lakes and coastal waters (including coastal estuaries) that states, territories, and authorized tribes officially recognize or designate for swimming, bathing, surfing, or similar activities in the water. This fact sheet summarizes beach monitoring and notification data submitted to EPA by the State of New York for the 2010 swimming season. Each summer, New York monitors bacteriological indicator levels at bathing beaches along Lake Erie, Lake Ontario, Long Island Sound, and the Atlantic Ocean as part of EPA's BEACH Act grant program. Indicator bacteria are used to detect pollution sources, such as sewage or stormwater runoff that could affect water quality at a beach. The New York State Department of Health contracts with local health departments, the New York City Department of Health and Mental Hygiene, and the New York State Office of Parks, Recreation, and Historic Preservation to provide up-to-date information regarding beach water quality conditions to the public. In 2010, beach water samples were collected from the State's 346 monitored coastal beaches and analyzed for E. coli (freshwater beaches) or enterococcus (marine beaches). Sample analysis and local predictive models resulted in 449 instances of beach closures or advisory postings to protect the public from swimming in potentially contaminated water. Public notification occurs if a sample exceeds the threshold of 235 E. coli colonies per lOOmL or 104 enterococcus colonies per lOOmL of water. New York's beach water quality is generally excellent; in 2010 the State's coastal beaches were open 97% of the time. Figure 1. New York coastal counties. Table 1.

When water quality standards are exceeded at a particular beach, New York issues a beach advisory that warns people to avoid contact with the ocean water. A total of 132 monitored beaches had at least one advisory issued during the 2010 swimming season. About 86 percent of New York's 449 notification actions lasted two days or less. Figure 2 presents a full breakdown of notification action durations. What percentage of days were beaches under a notification action? For New York's 2010 swimming season, actions were reported about 3 percent of the time (Figure 3). How do 2010 results compare to previous years? Table 2 compares 2010 notification action data with monitored beach data from previous years. In 2010, there were fewer beaches affected by advisories or closings, and fewer beach days affected by notification actions than in 2008 and 2009. What pollution sources possibly affect investigated monitored beaches? Figure 4 displays the percentage of New York's monitored beaches possibly affected by various pollution sources. In 2010, 55 percent of the beaches included storm-related runoff as a known potential source. No pollution sources were found at 42 percent of the beaches.
