Commercial POU installations improve drinking water quality in Grimes, Calif.
Long-term cost benefits of the point-of-use program for communities to comply with the arsenic rule
Water Quality Products asked Frank DeSilva, national sales manager for ResinTech, Inc. to share his thoughts on the potential market the new arsenic rule may create for POU/POE dealers.

The Jan. 23, 2006 deadline requiring water systems to comply with the new 10 ppb maximum contaminant level (MCL) for arsenic is fast approaching. Water Quality Products asked Greg Gilles, vice president of AdEdge Technologies, Inc. and WQP Arsenic Zone expert, to share his thoughts on the impact of the new standard.
In mid-2003, AdEdge was selected to implement three full-scale arsenic treatment demonstration projects with the U.S. Environmental Protection Agency (EPA) using its granular ferric oxide technology. At the Rimrock, Ariz., location, implementation began in September 2003 including engineering submittals and permitting by the Arizona Department of Environmental Quality. Upon completing site preparations and construction in early March 2004, AdEdge Technologies installed a new 100-gpm Adsorption Package Unit (APU) arsenic treatment system at the Montezuma Haven well site.

In early 2004, AdEdge was pre-qualified and invited to participate in an arsenic pilot study of commercial adsorption-based treatment technologies with Damon S. Williams & Associates (DSWA). As an outcome of the successful piloting and preliminary work with the engineer, AdEdge was chosen by Centennial Contractors to perform full-scale arsenic treatment using its granular ferric oxide adsorption technology at the New River Elementary School site in New River, Ariz., 15 miles north of Phoenix.

Many of these homeowners were unaware that arsenic was present in their wells and only became aware because they were either selling or buying a home.

Emerging commercial technologies are replacing the "old standards" for small water system (SWS) applications. In contrast to large community systems, competitive economics, simple operation and low waste production will drive changes in technology and engineering. Some out-of-the-box thinking will be necessary in the shift to provide simpler, packaged or preengineered arsenic treatment systems.
Arsenic Treatment for Small Public Water Systems
What research is being done at University's throughout the US? Colleges and universities across the U.S. are continuing their efforts in educating the population on the subject of arsenic. Both public and private universities are contributing their time, money, and expertise in areas of arsenic research such as geochemistry, health effects, and treatment options. Research programs, such as the ones listed below, are just a glimpse of the ongoing studies for arsenic. Ongoing research is necessary in order to continue to develop efficient and cost-effective solutions for the far-reaching problem of arsenic contamination.
