Protecting LI’s Drinking Water Against Lead Contamination

The Long Island Water Conference assures residents that there has been no lead contamination in their water supply for more than 30 years. All Long Island water providers continually test and treat for lead content.

To ensure the water supply is not contaminated with lead, all Long Island water suppliers comply with the United States Environmental Protection Agency’s (USEPA) Lead and Copper Rule. Suppliers are advised to treat the water by raising the pH to help prevent the leading of lead from household pipes and plumbing fixtures.

“On Long Island, public water suppliers have been providing treatment for corrosion control for over 30 years,” said Chairman of the Long Island Water Conference, Ralph Pugliese. “Water providers take every precaution to ensure a situation like the one in Flint, Michigan never occurs on Long Island. We are fully transparent with test results and would never withhold any information pertaining to resident’s safety and the well-being of Long Island families.”

The regulation requires all systems to monitor drinking water by sampling the tap water from multiple households throughout Long Island communities. If lead and copper concentrations exceed a certain level in more than 10 percent of customer samples, the system must take a number of actions to control the corrosion. It is also required to inform people what steps they can take to replace lead service lines and safeguard their water.

All results of testing are presented to residents each year in the Annual Water Supply Statement prepared by the individual water supplier.
