U.S. Environmental Protection Agency (EPA) - Environmental Technology Verification (ETV) Program
August 2007
Drinking Water Systems Center
Introduction
The 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)
supports the ETV Program. The DWS Center is
operated through a cooperative agreement with
NSF International.
DWS Center Key Features
The DWS Center's activities include development of
verification protocols and test plans, independent
testing and validation 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 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.
States Using NSF EPA Environmental
Technology Verification Reports
EPA/ETV Report Recognition
In a recent NSF survey of ASDWA members, twenty-nine
states reported they recognize NSF/EPA ETV reports for
drinking water treatment systems. Utah formally
references ETV reports in its regulations. In addition,
Massachusetts' water permit application mentions ETV
and the State of Washington's water system design
manual references ETV protocols for surface water
treatment. Twenty-four 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. In addition, testing
protocols under the DWS Center are referenced in
SWTR-LT2 Guidance documents.

Current Protocol Activity
I The ETV membrane protocol is included in
the USEPA's Long Term 2 Enhanced Surface
Water Treatment Rule's Membrane
Filtration Guidance Manual.
) The USEPA UV disinfection guidance
manual will replace the existing ETV UV
protocol.
Verification reports and protocols can be found on the
EPA andNSFweb sites: www. epa.gov/etv and
www. nsf.ors/info/etv.
Future Activities
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
I Inorganic Chemical Removal for Small Systems:
Brimac Environmental Services Inc. for
uranium reduction by adsorptive media
9 Emergency Response Water Treatment Systems
Department of Defense Expeditionary Unit
Water Purification (EUWP): testing at three
field locations: Gallup, New Mexico;
Selfridge Air National Guard Base,
Michigan; and Port Hueneme, California
