  1. THE EDWARDS AQUIFER:A Hidden Treasure Greater Edwards Aquifer Alliance

  2. WHAT IS AN AQUIFER? • An aquifer is any unit capable of storing and transmitting water in usable quantities • KARST AQUIFERS Karst: “landscape formed by dissolution of soluble rocks” • Limestone, dolomites, salts, gypsum, quartzites, more

  3. SEDIMENTARY AQUIFERS • Made of grains of other rocks • Grains do not fit tightly together • Space is left between the grains • Mechanical filtration occurs Pore space

  4. SEDIMENTARY AQUIFER Glacial Till • Water follows very torturous flow paths • Flow velocities on the order of cm to m/day

  5. REMEDIATION = POSSIBLE • Flow with groundwater flow direction • Contaminants travel slowly as a plume • Soluble • - Agricultural pollution: fertilizers • Insoluble • - Petroleum products
