   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.

                                                                               Environmental Protection

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:
