The District collects water quality measurements from water wells located with Victoria County.  The District collects field parameter measurements such as pH, temperature, conductivity, ORP, dissolved oxygen, and total dissolved solids.  The District collects water quality information such as ions, metals, nutrient information, and hydrocarbon levels when conditions warrant a greater degree of data collection.

On January 17, 2025, the District, in cooperation with Calhoun County GCD, Refugio GCD, and Texana GCD, funded a project to evaluate water quality across the Victoria, Jackson, Calhoun, and Refugio Counties to be completed by Daniel B. Stephens and Associates (DBSA) to serve as a baseline for future evaluations and trend analysis. 

The report titled Four County Groundwater Quality Study complied and documented water quality information regarding total dissolved solids concentration of groundwater, assigned formation information where possible, analyzed the data, and developed time-based water quality charts, and water quality contours for Calhoun, Jackson, Refugio, and Victoria Counties.  DBSA provided recommendations regarding monitoring that would be useful for improving water quality monitoring by the districts.
