In May 2011, a shocking 80 percent of the 59 water samples taken from various sites in the Hudson River were determined to be unacceptable by the Riverkeeper, a non-profit organization dedicated to improving water quality on the Hudson River. What makes water “unacceptable”? Sampled sites are tested for enterococcus, a human pathogen often found in sewage that can potentially cause health problems like Meningitis and urinary tract infection.
According to the Environmental Protection Agency (EPA), Enterococcus count standards vary for different sites (for beaches, state governments discourage swimming if the count is over 35 colony forming units per 100ml). As for the part of Hudson River bordering New York City, an enterococcus count greater than 104 units per 100mL is considered “unacceptable.” And, quite frankly, gross.
