Records of wells, driller's logs, water-level measurements, and chemical analyses of ground water in Brazoria, Fort Bend, and Waller Counties, Texas, 1966-74.

Reports describing the groundwater resources of Brazoria, Fort Bend, and Waller Counties, Texas, were prepared and published in 1973, 1972, and 1969, respectively. Sandeen and Wesselman (1973), in describing the resources of Brazoria County, tabulated records of wells, driller's logs, water-level measurements, and chemical analyses gathered during the course of this study. This report presents data (1966-1974) collected since the investigation by Sandeen and Wesselman (1973) and updates records tabulated by Wesselman (1972) in Fort Bend County and by Wilson (1969) in Waller County. These records are being collected in cooperation with the Texas Water Development Board to evaluate the groundwater resources of the Greater Houston-Galveston Region.
