Drinking Water Systems Center
Introduction
The NSF International (NSF) Drinking Water
Systems (DWS) Center is one of several US EPA
Environmental Technology Verification (ETV)
centers dedicated to producing credible
environmental performance data. The EPA
Office of Research and Development (ORD)
leads the ETV Program.
DWS Center Key Features
The DWS Center's activities include
development of verification protocols and test
plans, independent testing and verification
of equipment, conveying and supporting
government/industry partnerships to obtain
credible performance and cost data, and
preparation of product-specific verification
reports for broad dissemination. The DWS Center
has targeted drinking water concerns such as
arsenic reduction, microbiological contaminants,
particulate removal, disinfection by-products,
radionuclides, and other chemical contaminants.
A stakeholder steering committee and technical
panels help to advise the DWS Center on
verification activities and direction.
The DWS Center currently has twenty-six test
plans that outline testing procedures for various
technologies. The Center has prioritized the
following technology categories: low pressure
membrane filtration, alternative membrane
separation processes, adsorptive media and
resins, coagulation and alternative filtration
processes, UV & ozone disinfection and oxidation,
ion exchange, air stripping, cartridge/bag filter
processes, and on-site halogen generation
systems. The DWS Center has also evaluated
States Using NSF EPA Environmental
Technology Verification Reports
residential Point-of Use (POU) devices, Point-of-
Entry (POE) whole building systems, and mobile
water treatment systems for their ability to remove
chemical and biological agents of concern.
EPA/ETV Report Recognition
In 2007 NSF survey of ASDWA members, thirty-
five states reported they recognize NSF/EPA ETV
reports for drinking water treatment systems,
although mostly through policy (see map below).
Utah is currently the only state with a formal
reference to the ETV reports in their regulations.
Massachusetts' water permit application
mentions ETV and the State of Washington's
water system design manual references ETV
protocols for surface water treatment. Thirty-one
states indicated they would allow for reduced
pilot testing if the ETV report demonstrates
adequate performance. Most stated that they
would reduce the required pilot testing if source
waters were similar to those in the ETV report.

The DWS Center's future work is based on
market interest as a result of the Center being
supported by non-EPA funding sources. Some
projects in progress include the following:
Verification Testing
» Inorganic Chemical Removal for Small
Systems: Brimac Environ mental Services Inc.
for uranium reduction by adsorptive media
» LT2 Membrane challenge testing for Siemens
Memcor L10, L20 and S10 products
» UV reactor validation to Disinfection of the
Water Supply (DVGW 294)
Test Plan Under Development
» Test plan for UV verification of Samkun™ UV
reactor per the "German Technical and
Scientific Association for Gas and Water
Technical Standard Work Sheet W-294-2 June
2006, UV Devices for Disinfection of the Water
Supply"
