POU/POE Implementation Study for Arsenic Proves Feasibility

Source: 
Water Quality Assn.

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.

Troubled Waters Ahead

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.

Arsenic Treatment

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.

High Arsenic Levels

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.

'Out of the Box'

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 Overview Series - Part 6

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.

Arsenic Overview Series - Part 5

Research on arsenic can be broken down into three general areas -- health effects, treatment options and cost evaluations.There are more than 1,000 published research papers on health effects alone. This section provides an over-view of the most prominent research related to these areas which have impacted EPA’s decisions. There also are links to research organizations that can provide access to the specific projects conducted.
