The City of Mason addressed the need to improve its water system because of violations noted by the Texas Commission on Environmental Quality (TCEQ). Increasingly stringent regulatory requirements for radionuclides coupled with cyclical deterioration in raw water availability and quality were straining the capabilities of the City’s existing water system. The quality of the City’s groundwater sources was above the TCEQ’s and Environmental Protection Agency’s (EPA) Primary Drinking Water Standards Maximum Contaminant Level for Combined Radium and Gross Alpha Particles. As a result, eHT provided application assistance, project management, design and construction administration of a radionuclide pilot and treatment project. The project consisted of the construction of a new radionuclide reduction system (RRS) on the site of Groundwater Well No. 2, as well as a new supervisory control and data acquisition (SCADA) system to coordinate distribution system operations. Additional work included distribution system improvements, a new ground storage tank, and the replacement of two high service pumps at an elevated storage tank site.
