At the 2005 NMEHC there were three activities related to implementation of the new drinking water standard for arsenic. The morning session on 2 November dealt with the status of efforts in New Mexico and other parts of the country to comply with the new MCL for arsenic by the regulatory deadline of January 23, 2006. Invited papers described results of the Arsenic Water Technology Partnership, including bench-scale studies, pilot scale studies of innovative technologies, and economic analysis of the costs of different treatment technologies. Other talks described research by universities, national laboratories and federal agencies to develop new approaches to water treatment for arsenic and co-contaminants such as uranium, nitrate and radium. In the afternoon, commercial developers of innovative treatment technologies described project histories that demonstrate the effectiveness of their products. The Forum dinner included a presentation and abstract on the Global Arsenic Crisis.

On the next day, 3 November, these same technologies will be evaluated in a closed session by independent technical experts for possible use in pilot demonstrations to be conducted by Sandia National Laboratories at community sites in 2006.

New Vendor Focus for 2005: In addition to arsenic removal methods, this year, we encourage vendors of technologies suitable for simultaneous removal of arsenic plus other contaminants to participate. Other contaminants of concern include: nitrate, perchlorate, uranium and radium.
