Lead is a naturally occurring metal harmful to our health. It can be in air, soil, dust, food, and water. Lead was commonly used in gasoline and paint until the 1970s. It is still sometimes found in products such as ceramics, batteries, ammunition, and cosmetics. Lead was also used for centuries in plumbing because does not rust, crack or leak like other metals. In fact, lead’s chemical symbol, Pb, is from the Latin word for plumbing.
Although the U.S. Congress took steps to limit lead in pipes in 1986 and again in 2014, lead may still be in a home’s plumbing and fixtures. Lead in plumbing can contribute to lead in drinking water by slowly dissolving into the water it comes in contact with, or breaking off in tiny pieces as the water flows through in a process called corrosion.
There is no lead in the water that leaves the Aquarion treatment plant, or the large underground pipes it runs through to reach customers, called water mains. But, lead can enter your tap water through a service line, which is the line that brings lead from the main to your house and also from the pipes, plumbing and faucets inside your home.
Aquarion consistently complies with Federal and State water quality standards, including those for lead. Aquarion also adjusts the water’s chemistry to prevent corrosion that may result in lead at the tap. Each year, we report to customers the levels of lead and many other potentially hazardous substances that may be in water systems.

The U.S. Environmental Protection Agency’s Lead and Copper Rule (LCR) requires water systems test for lead and copper at the tap in certain homes. The tests focus on homes with lead service lines, which are expected to have higher lead concentrations.
Lead samples are required to be “first-draw samples,” or a sample taken from tap water that has stood motionless in the plumbing pipes for at least six hours. Water systems, like Aquarion, compare sample results from these homes to an action level (AL) of 0.015 milligrams per liter (mg/L), also known as 15 parts per billion. If 10 percent of the samples from these homes have lead above the 15 parts per billion (ppb) action level, then the systems must conduct public education, corrosion control treatment modification, and lead service line replacement if applicable.
Aquarion conducts many other water quality tests to comply with U.S. Environmental Protection Agency (EPA) regulatory requirements. To learn more about water quality in your area, read our Water Quality Reports.
On December 16, 2021, EPA announced Lead and Copper Rule Revisions (LCRR). The LCRR requirements are effective October 2024. Aquarion has proactively taken steps to meet these requirements. Major changes from the LCRR include:
Aquarion performs over 175,000 tests of its water annually.Learn More
