AdEdge Technologies, Inc, a provider of adsorbent products and integrated treatment systems for arsenic removal from water and wastewater, and the Water District of Black Canyon Community, Ariz., announced that AdEdge has undertaken a turnkey project to provide arsenic treatment solutions for the town’s drinking water supply wells. The city, located approximately 40 miles north of Phoenix has three main supply wells, and serves a population of approximately 2,300 people.
According to the U.S. Environmental Protection Agency (EPA), more than 4,000 public drinking water systems throughout the United States contain arsenic concentrations exceeding the new federal standard for arsenic, which was lowered from 50 parts per billion (ppb) to 10 ppb. In Arizona alone, the Department of Environmental Quality (ADEQ) has identified more than 300 regulated public water systems that must implement a solution to meet the new arsenic standard by January 2006. The number of affected systems represents a significant percentage of systems in the state, most of which are small systems serving communities less than 3,000 people. ADEQ is hosting an Arsenic Technology Fair on September 29th, 2004 at the Mesa Convention Center to assist public water systems in identifying technologies that will help communities comply with the new arsenic standard. AdEdge will be exhibiting a small arsenic removal system during the exhibit.
AdEdge Technologies uses a granular ferric oxide to reduce arsenic contamination in small municipal, commercial and industrial applications. AdEdge has used the technology in multiple public drinking water systems in the United States, including one of its nationwide EPA Demonstration Projects in nearby Rimrock, Ariz. This demonstration project that began earlier this year, utilizes an AdEdge Adsorption Package Treatment System, and has been treating arsenic ranging from 40-80 ppb to below 2 ppb. This site is one of three EPA demonstration projects being implemented by AdEdge with the intent of demonstrating commercial-ready technologies that are suited for small systems. This is the third recent public water system project to be implemented by AdEdge in Arizona, including an installation for an elementary school in New River, Ariz., for the Deer Valley Unified School District.
