What you need to know

A lead service line is the pipe that connects your home to the public water main under the street. If your line is made of lead, water can pick up lead as it travels to your tap—especially if the water is acidic or your pipes are old.

The presence of a lead service line does not automatically mean your water is unsafe to drink. Lead levels depend on water chemistry, pipe age, water usage patterns, and whether your home has other lead sources (like lead solder or fixtures). Testing is the only way to know your actual exposure.

Your water systems

Water Authority of Western Nassau serves the vast majority of New Hyde Park's population (120,000 residents) and has identified 260 lead service lines in its service area.

Amagansett Laundry serves 50 people and has identified 260 lead service lines recorded—which likely reflects a data reporting difference rather than an unusually high concentration. Contact this utility directly if you're served by them to clarify their inventory.

Next steps for residents

  • Find out if you have a lead service line: Contact your water utility (Water Authority of Western Nassau is the primary one) and ask for your service line material. Provide your address. They may have this on file or can help you arrange an inspection.
  • Get your water tested: If you have a lead line or are unsure, ask your utility about free or low-cost testing. The EPA recommends testing the first draw of water in the morning.
  • Talk to your pediatrician or call the CDC: If you have young children or are pregnant, discuss lead exposure risk. The CDC has guidance on blood lead testing and reducing exposure.
  • Ask about replacement programs: Some utilities offer programs to replace lead lines. Contact your utility to learn about costs, timelines, and any financial assistance available.

Common questions

How do I know if my house has a lead service line in New Hyde Park?

Contact Water Authority of Western Nassau with your address and ask for your service line material. They maintain records of known lead lines. You can also visually inspect the pipe where it enters your home—lead is soft, dull gray, and can be scratched with a coin.

Is the water in New Hyde Park safe to drink if there's a lead service line?

The only way to know your actual lead levels is to test your water. Many homes with lead lines have low or undetectable lead due to water chemistry and other factors. Contact your utility about free or reduced-cost testing.

Will my utility replace my lead service line for free?

It depends on your utility's replacement program. Water Authority of Western Nassau may offer assistance, rebates, or low-interest loans. Contact them directly to learn what options are available in your area.

What should I do if I'm worried about lead and my kids?

Talk to your pediatrician about your concerns and ask whether blood lead testing makes sense for your children. The CDC also has evidence-based guidance on reducing lead exposure at home.
