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 new arsenic rule takes effect on Jan. 23, 2006. The U.S. Environmental Protection Agency (EPA) has set the new arsenic limit to 10 parts per billion (ppb), down from the previous limit of 50 ppb. Municipal water utilities are the major water treatment facilities that are faced with these changes. All purveyors of drinking water are affected, including public and private systems.

After another busy year, it is time to take a look forward to the issues and developments that will likely have the greatest impacts on the water treatment industry’s growth and direction in 2006. In the upcoming year, the industry will experience the results of past efforts while setting the stage for new projects and goals.
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.

A joint study by AWWARF (American Water Works Association Research Foundation) and the U.S. EPA, POU/POE Implementation feasibility study for arsenic treatment, shows that the use of POU/POE solutions for arsenic removal is both efficacious and cost-effective.
The looming deadline for municipal systems to ensure an arsenic MCL (maximum contaminant level) of less than 10 ppb is a difficult--if not financially impossible--target for small systems across the US.
As we near January 2006, there are more than 5,000 small water systems that are not compliant with the upcoming 10 ppb total arsenic rule. Iron oxide (hydroxide) based sorbents like granular ferric hydroxide (GFO) appear to be the best choice for removing total arsenic from small municipal drinking water systems, but preliminary studies show there may be disposal problems associated with arsenic spent sorbents from drinking water applications.

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.
