 How to Participate


The goal of the Arsenic Removal Technology Demonstration Program is to demonstrate commercial-ready arsenic removal technologies and engineering solutions at various sites across the United States. EPA conducted Round 1 of the program in 2002. In 2003, EPA announced the start of Round 2.

Selection of a demonstration site is based on a site’s water quality, its geographical location, and the anticipated cost. The demonstrations are conducted at small drinking water systems that serve 10,000 customers or fewer. In addition, utilities must be classified as either a community public drinking water system or a nontransient, noncommunity water system.

If a utility is interested in volunteering for the program, the utility must complete a Demo Site Information form (PDF) (2 pp, 67.5 KB)and contact their state drinking water program officials. The state officials will formally submit the information to EPA through the Association of State Drinking Water Administrators Exit EPA Disclaimer (ASDWA). ASDWA represents the state drinking water program administrators who ensure drinking water is protected in the state. The state must approve any treatment technology or engineering installation at the site before a demonstration can be started.

The Demo Site Information form asks for information such as population served, source water, system capacity, existing treatment, and water chemistry. If the source water contains contaminants, other than arsenic, that exceed the Maximum Contaminant Level (MCL), the contaminants should be noted on the form. If the utility’s arsenic level is close to the MCL, this too should be noted on the form.

Once the list of volunteer utilities is compiled and submitted, EPA selects candidate demonstration sites based on water chemistry and flow at the site and the availability of facilities and operators. EPA will collect water samples at the candidate sites for analysis in order to confirm data and to fill in data gaps.

The list of candidate utilities is included in a formal request for vendor and engineering proposals. Technology vendors and engineering companies propose their technology or engineering solutions for the water supplies on the list. Candidate utilities may be contacted by vendors during this time to determine whether their technology is suitable for the water supply. When EPA receives the technical proposals, an independent panel of experts reviews them and recommends the best technologies or engineering approaches for each site. Using the recommendations, EPA works with the utility and the technology vendor or engineering firm at each site to conduct the demonstration project.

EPA will not provide a grant or money directly to the utility or the technology vendor. EPA will purchase any equipment or engineering services through an independent contractor and will pay for the installation of the equipment at the site. EPA will provide supplies such as chemicals or media if they are needed. As a result of these demonstrations, the utility will likely incur some costs for things such as electricity or an additional operator.

EPA will work with the utility to draft an agreement that outlines the terms of the research demonstration. EPA will not proceed with the demonstration without the full approval of the utility and the state drinking water program.

Once the round of demonstrations is underway, the utility, EPA scientists, and contractors will collect data and samples and interact with the system operator. The demonstrations are anticipated to last one year. At the end of the study, if the utility does not think the technology will suit the needs of the system, EPA will remove the equipment from the site.
