The sewage water supply in western New York is being treated by a new industry in which sewage plants are pumping out water at a rate of about 2.6 million gallons a day.
The amount of water being discharged into waterways and the amount of pollutants it contains is a concern because the city has a long history of poor water quality and is expected to have a more acidic future.
That could lead to pollution problems in the region and the state, including increased algae growth and more harmful bacteria, a study by the New York State Department of Environmental Conservation said.
The study examined sewage treatment plants in five counties in New York City and the Bronx, and compared the levels of nitrogen and phosphorus in water.
In New York, wastewater treatment plants can discharge about 1.3 million gallons of wastewater a day, and the study found that, in the Bronx alone, about 3.5 million gallons were discharged from the facilities.
The wastewater is then treated by the city’s municipal water supply, which has a limited capacity to treat it.
The city’s water supply also has a high concentration of arsenic and other toxic chemicals.
In the study, the New Yorkers studied in New Jersey were more likely to be exposed to arsenic, and they also had higher levels of nitrates and nitrates in their blood than people in the rest of the country.
A spokesman for the state Department of Health said the study was “incorrect” and that it should not be used to suggest that the treatment plant is the cause of problems in New Yorkers.
The sewage plant at Westchester County Public School in Queens, which is owned by the State Water Authority, does not have any control over the amount discharged.
The plant has been a major focus of federal scrutiny since it was reported to have failed to treat sewage properly, according to the federal Centers for Disease Control and Prevention.
The agency has also called on the state to take more aggressive action to improve sewage treatment in New England.
It has warned that the state’s treatment plants could be the most significant water pollution problems for New York in decades.
The EPA, which oversees the agency, issued a report in July saying that New York was in danger of becoming “the first state in the nation to experience a public health crisis related to inadequate treatment.”
A study released this month by the University of Massachusetts at Amherst found that New Jersey has the worst treatment quality in the country, and that pollution in the state is expected more than double the national average by 2050.
In June, the state agreed to improve the state water supply by 10 percent and pay $8.5 billion in federal payments to cover future costs, but said it will take at least another 10 years to make the necessary improvements.
The state has also agreed to a $50 million payment to help pay for the new sewage treatment plant.
