To our Valued Customers:
We are committed to providing you, our customers, with water that meets and often surpasses all water quality regulations. Our state-of-the-art 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 assure our customers that the water we deliver to them is of high quality.
Please click on the link below to view the Suffolk County Water Authority's 2020 Annual Drinking Water Quality Report, which covers all of our testing for the calendar year 2019. The report also 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.
