THE EDWARDS AQUIFER: A Hidden Treasure Greater Edwards Aquifer Alliance 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 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 SEDIMENTARY AQUIFER Glacial Till •Water follows very torturous flow paths •Flow velocities on the order of cm to m/day REMEDIATION = POSSIBLE •Flow with groundwater flow direction •Contaminants travel slowly as a plume •Soluble - Agricultural pollution: fertilizers •Insoluble - Petroleum products
