Research Areas

EPA's arsenic research provides the basis for water system compliance with the new Arsenic Rule. These areas are targeted:

• Treatment Technologies
• Research on Arsenic in Ground Water
• In-House and Field Research
• Environmental Technology Verification (ETV) Program
• Grants and Funding

One of the issues associated with the new Arsenic Rule is the cost of bringing water systems, especially those in smaller communities, into compliance. To address this issue, EPA is evaluating arsenic removal technologies for their cost effectiveness. EPA has used a significant portion of Congressional funding to support demonstrations of newly developed low-cost treatment technologies.

In addition, EPA issued its Implementation Guidance for the Arsenic Rule in August 2002. This document provides guidance to EPA regions, states, and stakeholders for implementing the Arsenic Rule. It incorporates comments received on the previous drafts of the guidance and from Arsenic Rule training sessions held throughout the country.

With ongoing development of new scientific data, innovative methods, and cost-effective technologies, the goals of arsenic treatment technologies research are closely aligned with EPA's goal to achieve and protect clean water systems, and to maintain public safety and health.
