ANN ARBOR, Mich. — NSF International announced it has published the first consensus-based American National Standard to evaluate municipal water filtration technologies’ performance in removing Cryptosporidium from public drinking water supplies, according to a press release.

The new standard, NSF/ANSI 419: Public Drinking Water Equipment Performance – Filtration, incorporates federal and state regulatory requirements, “assisting state regulators in verifying compliance while reducing time and costs for manufacturers by streamlining the testing process,” stated the release.

Dow Chemical Company, Hydranautics, Hyflux Limited, Inge GmbH, and Qua Group LLC are the first to have products earn NSF/ANSI 419 certification, and several other water filtration technologies are currently undergoing the testing and certification process, reported the release.

In addition to federal and state requirements such as certification to NSF/ANSI 61: Drinking Water System Components – Health Effects, the NSF/ANSI 419 standard, continued the release, incorporates the U.S. Environmental Protection Agency’s (EPA) Long Term 2 Enhanced Surface Water Treatment Rule (LT2).

The LT2 Rule, noted the release, was created by EPA to ensure Cryptosporidium is effectively removed from public drinking water and applies to all public water systems using surface water or groundwater that is under the direct influence of surface water.

“Water treatment technologies certified to the NSF/ANSI 419 standard have been tested to verify they effectively remove Cryptosporidium in drinking water, which is known to cause gastrointestinal illness,” said Clif McLellan, vice president of NSF International’s Global Water Division. “Instead of every state drinking water agency having to review each validation report for each product, state regulators can now verify compliance through the official listings found on NSF’s website.”
