New York needs to do better with monitoring drinking water contaminants including in Oneonta. That’s the conclusion of a report released by State Comptroller Thomas Dinapoli. The study found that in Oneonta 4 out of 25 violations did not have notices or public notification issued. Overall the audit determined that 58 of the 126 water violations sampled were never made public with six of those violations possibly resulting in serious health effects. New York has more than 9,100 public water systems which supply water to all but 5 percent of customers.
