Calgon Carbon gets USD 13.2m water treatment contract for removal of 1,2,3-TCP.

BANKING AND CREDIT NEWS-March 29, 2017-Calgon Carbon gets USD 13.2m water treatment contract for removal of 1,2,3-TCP


Calgon Carbon Corporation (NYSE: CCC) and California Water Service (Cal Water) have signed a system supply contract valued at USD 13.2m, under which Calgon Carbon will provide granular activated carbon (GAC) and associated equipment systems to treat more than 30 drinking water wells contaminated by 1,2,3-Trichloropropane (1,2,3-TCP), Calgon said.

The contract, which starts in 2017, is the largest drinking water-related carbon adsorption equipment project in company history.

Under the terms of the contract, Calgon Carbon will supply 104 GAC adsorption vessels and over 2 million pounds of Filtrasorb 400 GAC to treat more than 40 million gallons of water per day at 38 of Cal Water's well sites. The GAC adsorption equipment will be installed in stages, with all of the equipment expected to be in service by June 2018. Both the activated carbon and vessels will be manufactured in the United States.

GAC removes 1,2,3-TCP from water through a process called adsorption. The California Division of Drinking Water expects that GAC will be named as the best available technology (BAT) in the new TCP regulation.

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). In 1992, the state of California added 1,2,3-TCP to the list of chemicals known to the state to cause cancer, pursuant to California's Safe Drinking Water and Toxic Enforcement Act.

The compound is currently not regulated by the U.S. EPA, although it is on the Contaminant Candidate List 4 for future regulation. On March 3, 2017, the California State Water Resources Control Board proposed a draft maximum contaminant level (MCL) for 1,2,3-TCP of 5 parts per trillion.

Cal Water is the largest subsidiary of the California Water Service Group, which also includes Washington Water Service Company, New Mexico Water Service Company, Hawaii Water Service Company, HWS Utility Services, and CWS Utility Services. California Water Service Group is the largest investor-owned American water utility west of the Mississippi River and the third largest publicly traded in the country.
