FACT SHEET: Selection of Round 2
Arsenic Treatment Technology
Demonstrations
      ACTION: The U. S. Environmental Protection Agency (EPA) is announcing the selection of thirty
      (30) arsenic treatment technology demonstration sites across the U.S.

      SUMMARY:  This announcement of the selection of thirty (30) arsenic treatment technology

Vale, OR
      Twelve (12) demonstration sites were selected in 2003 as a part of Round 1 of the program. This
      announcement brings the total number of demonstrations to forty-two (42).

      The objective of this research demonstration program is to evaluate the efficiency and effectiveness
      of drinking water treatment technologies, process modifications and engineering approaches to meet
      the new arsenic standard under varying source water quality conditions.

      The list of technologies to be demonstrated by site is still under negotiation with the site and
      oversight agency.

      BACKGROUND:  On October 31, 2001, the Agency announced a $20 million arsenic treatment
      research and technical assistance program to help small communities meet the new arsenic standard.
      Drinking water systems have until January 23,2006, to comply with the new standard, which is 10
      ug/1 (10 parts per billion).

      The research program is organized into five (5) parallel efforts:

      1. Emerging technology support. Through the Small Business Innovation Research (SBIR) program
      and Science to Achieve Results (STAR) program various early development innovative treatment
      processes for cost-effective removal of arsenic in drinking water have been supported.
                                                             600F04900

-------
2. Full scale long-term treatment technology research demonstrations of commercially ready
technologies at a set of geographically diverse public water supplies to evaluate performance,
reliability and cost.

3. Short-term performance verification studies of commercially-ready arsenic adsorption
technologies under EPA's Environmental Technology Verification (ETV) Program. Four treatment
technologies have been verified.

4. Enhanced internal research program. This research is aimed at residuals management from
arsenic treatment processes, distribution system effects, improved exposure studies and analytical
methods and treatment process optimization.

5. Technical assistance and training for states, water systems and technical assistance providers to
help systems achieve compliance.

This action implements part 2 of the research program for 2004.
