Lead-free and NSF 372 Certified Waterstops



Lead is a metal used in the plumbing and waterworks industry. Lead can dissolve into the water supply from drinking water system components it contacts (pipes, fittings, waterstopset al.). The maximum lead content in drinking water system components is 0.25%, as defined by the NSF 372 Standard.


Earth Shield® polyvinyl chloride waterstops are certified to NSF/ANSI 372 and conforms with the lead content requirements for the U.S. Safe Drinking Water Act.
