Water Quality Reports

 

Dear Customers:

 
We are committed to providing the highest quality drinking water to our customers. Our laboratory tests our water at the wellhead, at various stages of treatment and within the distribution system for bacteria and a wide range of inorganic and organic chemicals. In fact, we test our drinking water for far more chemicals than required and at a frequency far in excess of local, state and federal regulations. Because of these stringent safeguards, we can reassure all our customers that the water we deliver to them meets all drinking water standards and guidelines.
 
If you click on the link below, it will take you to the Suffolk County Water Authority's 2014 Annual Drinking Water Quality Report. This report includes charts, data, maps and information about the quality of your drinking water. I hope the report answers all of your questions, but if not, please do not hesitate to call our Customer Service Center at (631) 698-9500.
