EPA's Water Treatment Demonstration Project to Reduce
Amount of Arsenic in Springfield, OH, Drinking Water
Arsenic is a naturally occurring contaminant found in
ground water in various locations throughout the United States. Research and development
efforts at EPA have identified certain technologies that remove arsenic from drinking water.
Some community water systems often face challenges in choosing the right technology to
reduce the level of arsenic. Therefore, in select demonstration projects across the country,
just like this one in Springfield, EPA is partnering with municipalities and equipment
producers to bring the most appropriate drinking water technology into the field and
demonstrate their effectiveness.
Researchers from EPA's National Risk Management
Research Laboratory (NRMRL), headquartered in
Cincinnati, Ohio, are working in partnership with
Chateau Estates in Springfield, OH, and a contractor
to install and operate a water treatment technology
aimed at reducing the level of arsenic in local drinking
water. Operation of the demonstration project began in
September, 2005, and is being regularly monitored to
determine progress.
Background
Chateau Estates' new arsenic
water treatment equipment
The Project
New water treatment equipment is installed to reduce arsenic in a community's drinking water.
The water quality is then monitored to verify the effectiveness of the treatment. The equipment
used in the Chateau Estate installation is produced by AdEdge Technologies, Inc., working
under a Cooperative Research and Development Agreement. The equipment was matched to
characteristics of the source water. While Chateau Estate will operate the new equipment,
scientists from Battelle. an EPA contractor in Ohio, will track the operation of the arsenic
removal technology by analyzing weekly water samples. EPA will use the results from this
project and others like it to demonstrate new methods for arsenic removal from drinking water.

The Goal
The goal of this project is to demonstrate and verify the effectiveness of AdEdge
Technologies, Inc. technology in reducing levels of arsenic in the drinking water from
around 25 parts per billion (ppb) to 10 ppb or lower. Operational cost is also being studied.
Expected Outcomes
•	Other small communities will gain knowledge about the performance of arsenic
removal technology through the results of the demonstration project. The results
will assist them in selecting the most appropriate and cost effective technology to
use at their sites.
•	Residents will benefit by having arsenic levels in their drinking water reduced
below 10 ppb, complying with the new EPA standard for arsenic in drinking
water.
