Measures taken during the last two decades have greatly reduced exposures to lead in tap water. These measures include actions taken under the requirements of the 1986 and 1996 amendments to the Safe Drinking Water Act and the U.S. Environmental Protection Agency’s (EPA’s) Lead and Copper Rule.

Even so, lead still can be found in some metal water taps, interior water pipes, or pipes connecting a house to the main water pipe in the street. Lead found in tap water usually comes from the corrosion of older fixtures or from the solder that connects pipes. When water sits in leaded pipes for several hours, lead can leach into the water supply.

The public drinking water supplies serving Cuyahoga County are recognized as safe and the water quality is routinely checked per regulation. The source water, whether it is Lake Erie, Rocky River, or a well is free of lead.

Situations may occur where the private distribution system may contribute lead to the water if inactive for extended periods of time.  This may be a concern in large distribution systems such as schools, and especially if the water pipes and fixtures were installed prior to 1986.

It is recommended that these systems institute a flushing protocol after a weekend of non-use.  This protocol is included on page 56 of the EPA’s 3T’s for Reducing Lead in Drinking Water in Schools publication.

Concerns regarding the public drinking water supply should be directed to the entity that provides water for your facility.
