Association of Arsenic With Iron Particles
|The Environmental Technology Verification (ETV) Drinking Water Systems Center and the Pennsylvania Department of Environmental Protection participated in a cooperative arsenic treatment technology study. The ETV testing involved three Pennsylvania community water systems that have arsenic in their source water exceeding the new Maximum Contaminant Level and that appeared to be representative of other small communities.
An initial meeting of Pennsylvania state regulators, the communities, and representatives of the National Science Foundation International was held July 16, 2002 in Harrisburg, Pennsylvania. ETV testing began in the fall of 2002. Vendors committed to participating include ADI International, Inc.; Tetra Process Technologies, a subsidiary of Severn Trent Services; Water Remediation Technology, LLC; and Kinetico Incorporated with Alcan Chemicals. Gannett Fleming of Harrisburg was the field testing organization for this ETV arsenic study. McKelvey Environmental Management coordinated many of the logistics of the ETV testing on behalf of the National Science Foundation.
The ETV Drinking Water Systems Center and the University of Alaska at Anchorage (UAA), an EPA Technology Technical Assistance Center, also worked together on a small system arsenic ETV test. Three sites were identified for possible ETV testing of arsenic small-systems technologies. The ETV testing in Alaska involved one of the three small-system sites. Testing began in 2002. UAA was selected for this ETV arsenic study because it is fully qualified; it contributed to this work from its Technology Technical Assistance Center funds. A request for arsenic treatment technologies remains open for other sites in Alaska.
