Organizations to use harmonized chemical risk assessment processes during certification

April 24, 2013

ANN ARBOR, Mich. — The harmonized process will be used by all five certification organizations immediately.

ANN ARBOR, Mich. — To further protect public health, reduce duplicative costs, increase efficiency and promote transparency of human health risk assessment action levels, CSA Group, NSF International, IAPMO R&T, UL and the Water Quality Association will now use harmonized procedures to develop action levels for unregulated chemical contaminants originating from products in contact with drinking water, according to a press release.

The harmonized process will be used by all five certification organizations immediately.

Products that contact drinking water, such as pipes and treatment chemicals, treatment devices and faucets, can contribute chemicals to drinking water.

In the late 1980s, NSF International developed American National Drinking Water Standards for chemicals and products that come in contact with drinking water (NSF/ANSI 60: Drinking water treatment chemicals – Health effects and NSF/ANSI 61: Drinking water system components – Health effects).

Products certified to these standards do not contribute currently known chemical contaminants to drinking water at concentrations that could cause adverse health effects, noted the release.

The certifying organizations are working together to consolidate more than 650 previously established action levels and to harmonize the external peer review process for all future risk assessments through the assistance of the NSF Health Advisory Board (HAB).
