The recorded concentration of Carbon Tetrachloride (CCl4) in the Freeman School District’s Production Well, prior to treatment, exceeds the EPA’s maximum contaminant level of 5 parts per billion. The goal for the project is to develop a treatment solution that would provide Freeman School District with potable drinking water with reduced concentrations of CCl4. We evaluated three active treatment alternatives, including Granular Activated Carbon, Air Stripping, and Reverse Osmosis, and one passive alternative, constructing a new well outside of the contaminated plume of CCl4. To evaluate which alternative was best fit for the needs of the school district, we assessed the following criteria: feasibility, life cycle costs, maintenance, operation requirements, and waste management.
