Ron Fiesler, General Manager of the Blanco/Pedernales Groundwater Conservation District, was our guest speaker at the October 4 club meeting. He emphasized that everyone concerned with groundwater is very aware of the need to use good science. He showed us maps that illustrate the various layers of the Trinity aquifer. Our District works cooperatively with nine other groundwater districts and plan for 50 years into the future in terms of water needs, quality, preservation, etc. Ron responded to several questions about both wells and rainwater collection systems.
