2022-06-272022-06-272008https://dc.statelibrary.sc.gov/handle/10827/44639Williamsburg County, S.C., has numerous substantial ground-water aquifers. Most are in sand-and-clay formations of Cretaceous Age, like the other counties of South Carolina’s Coastal Plain. Wells as deep as 1,200 feet provide water of suitable quality for public supply, industry, and agriculture. Many wells produce more than 200 gallons per minute; the largest yield recorded is 1,900 gallons per minute. Chemical analyses of the well water indicate dissolved-solids concentrations generally less than 300 milligrams per liter. The water is usually very soft and low in iron. Cloudiness caused by aragonite suspension has been an occasional problem. Withdrawals from wells in the Hemingway and Andrews areas have caused depressions in the potentiometric surface in those localities. This can be ameliorated by reduction in pumpage or repositioning of wells. Artificial recharge, using surface water, is a potential means of restoring the artesian water level.application/pdfDocumentCopyright status determined to be in the public domain on April 27, 2020 by United States Supreme Court ruling (Georgia et al., Petitioners v.
