Also called the "Memphis Sand Aquifer", or the "Sparta Aquifer" outside of Tennessee, the underground formation is well known for its ancient, clear water. Common Causes of Well Failure 2 (1 Hr.) 3), though this may be a result of the resolution of the ground-water model or of the contour interval used. Ground-water depressions alternatively may be the result of discharge of ground water from the surficial aquifer by the downward movement of ground water into the underlying aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. For more information, see question #1 above. I am a real estate agent or lender and I have a buyer who is interested in purchasing a home with a private water supply. The quality of groundwater used for public supply was assessed in 25 principal aquifers (PAs) that account for 84% of groundwater pumped for public supply in the U.S. (89.6 million people on a proportional basis). excavations in the United States. Watertight casing should extend at least six (6) inches above ground level; a minimum of two (2) feet for areas subject to flooding. -how is the well developed Consult the NEC for more information. Information in this dynamic database is constantly changing as records are updated daily. Phone: 866-522-2681, What: Scheduled Webinars, Training, Conference; Workshops For a well on a hillside, the uphill side of the well should be designed to prevent runoff from entering the well. What do I do now? The water table does not always mimic the topography due to variations in the underlying geological structure (e.g.,folded, faulted, fractured bedrock). TDEC does its best to maintain consistency between the federal and state systems, but this is now a manual process and corrections take time. The presence of the mounds may be the result of topography, less permeable aquifer materials, and (or) the presence of recharge areas either due to the infiltration of precipitation or some other source, such as losing streams, UIC systems, septic systems, irrigation, or injection wells. Water Well Design Gentler gradients occurring in areas of higher permeability and gentler relief are most common in the low-lying areas along major rivers and streams and in the terrace deposits extending in an area approximately bounded by the Columbia River to the north, the Willamette River to the west, and the Boring Hills to the southeast.
