When water leaves the Northern Kentucky Water District’s (NKWD) treatment plants, it does not contain lead. Lead in drinking water is primarily from materials and parts connected to home plumbing and service lines. A service line is the pipe connecting your home to the water main. If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children.
History of Lead Pipe for Service Lines:
Around the 1950’s, lead service line material transitioned to copper.
In 1988, the use of lead pipe and lead solder for joining copper piping and fittings was banned in Kentucky.
In 2014, the standard lead limits in brass faucets and fixtures were reduced from 8% to .25%.
The United States Environmental Protection Agency (EPA) published a regulation in 1991 to control lead in drinking water at customers’ taps. NKWD has been in continuous compliance with these lead standards.
NKWD is required to provide treatment that reduces the likelihood that lead will be released from pipes and fixtures. This is done by adjusting the water’s pH and by adding a corrosion inhibitor, a chemical that provides a barrier to protect the pipe materials from releasing lead into the water.
The EPA regulation includes testing for lead in water samples collected from customers’ homes. The most recent round of lead testing completed in 2021 showed there were no sites above the lead action level* of 15 parts per billion. However, because every home is different, the amount of lead in your tap water may be lower or higher than the monitoring results for the selected sites.
