Calgon Carbon announced that the Company and RC Foster Corporation have signed a system supply contract valued at $2.3 million in California.
Under the contract, Calgon Carbon will provide granular activated carbon (GAC) and associated equipment systems for the removal of 1,2,3-Trichloropropane (1,2,3-TCP) from groundwater in the city of Chino, CA.
Under the terms of the contract, Calgon Carbon will supply a total of 16 GAC adsorption vessels and 320,000 pounds of Filtrasorb 400 GAC to the Benson Treatment Plant and the Eastside Treatment Plant. The systems will treat up to 5 million gallons of water per day at each site.
GAC removes 1,2,3-TCP from water through a process called adsorption. GAC is expected to be the Best Available Technology (BAT) for 1,2,3-TCP treatment.
1,2,3–TCP is a manmade, colorless, chlorinated hydrocarbon that was found in soil fumigants commonly used in California prior to the 1990s. 1,2,3-TCP causes cancer in laboratory animals (U.S. EPA, 2009).
“Calgon Carbon is excited to be part of a solution that will provide so many public water systems with safe drinking water,” said James Coccagno, executive vice president of the Core Carbon and Services Division.
“With 1,2,3-TCP detected in many groundwater sources in California, it’s reassuring to know that the City of Chino has taken proactive steps to remedy the problem in their area,” Coccagno added.
“With the installation of GAC adsorption systems, our client, the City of Chino, intends to be fully prepared to meet the new MCL,” said Robert Foster, president and CEO of RC Foster Corporation.
“Protecting the customers’ health is the City’s highest priority and we are pleased to partner with Calgon Carbon, a leader in activated carbon treatment technologies and contaminant removal,” Foster added.
