BACKGROUND: The Palmyrita Water Treatment Facility (Palmyrita) removes organic compounds 1, 2-dibromo-3- chloropropane and 1,2,3-Trichloropropane from groundwater produced in the North Orange well field. Treatment is achieved by using granular activated carbon (GAC) to absorb the organic compounds, which is the United States Environmental Protection Agency approved drinking water treatment method. Approximately 2.5 billion gallons of groundwater are treated annually at Palmyrita for domestic use. The contract is for three years, with a term ending December 31, 2021, and it is anticipated that there will be approximately 50 GAC removal and replacement events during this time. Approximately 16 removal and replacement events occur annually. The scope of work includes all work needed to replace up to 20,000 pounds of GAC at each vessel, including: 1) removing and legally disposing of spent carbon, 2) inspecting and disinfecting the vessels, and 3) adding virgin carbon into the vessels.
