  7. Granular Activated Carbon Removes PFOA From Drinking Water
    12/7/2016

    In the fall of 2015, a small village on the border of Vermont in New York State, tested positive for Perfluorinated Compounds (PFCs), specifically Perfluorooctanoic Acid (PFOA), in the municipal drinking water. The influent levels of PFOA in the water were above 600 ng/L, and thus considered harmful to village residents. Realizing that PFOA was on the U.S. EPA Contaminant Candidate List, the Village solicited the services of engineering firm CT Male Associates to investigate treatment options and provide a treatment system.

  9. Granular Activated Carbon Removes 1, 2, 3 – TCP
    8/4/2016

    What is 1, 2, 3 - TCP? 1, 2, 3 - TCP is a man-made, colorless, chlorinated hydrocarbon that is used as a degreasing and cleaning agent and industrial solvent. It was also used as a chemical in pesticides for low growing crops such as potatoes, tobacco, and beets. 1, 2, 3 - TCP passes through soil and leaches into ground water, contaminating drinking water sources. 1, 2, 3 - TCP is a non-aqueous liquid that is more dense than water, making it difficult to remove from ground water wells. This compound is currently unregulated by the USEPA, although it is on the Contaminant Candidate List 4 (CCL4) for future regulation.

  10. Granular Activated Carbon: A Long-Term Solution For Meeting DPB Compliance
    7/31/2017

    When the Cobb County-Marietta Water Authority (CCMWA) anticipated the need to upgrade the Hugh A. Wyckoff water treatment plant, they turned to granular activated carbon (GAC) technology after vetting several alternatives. The plant, a wholesaler in a two-plant system, processes up to 72 million gallons per day and serves about 350,000 people. Comprising of Wyckoff and the James E. Quarles treatment plant, CCMWA is the second largest water provider in Georgia.
