This report, the fifth in a series of ' atlas-type ' reports, summarizes the large amount of unpublished data available for the Eutlaw-McShan aquifer in Mississippi. The Eutaw-McShan aquifer, of Cretaceous age, consists of the interconnected irregular sand beds in the Eutaw and McShan Formations. The aquifer contains fresh water in an area of about 8,000 sq mi in northeastern Mississippi. Water produced from the aquifer by 59 water systems and several industries in 1975 averaged about 24 mgd. Water levels have declined about 200 feet below levels of the early 1900 's at Tupelo and West Point and it is estimated that the aquifer is developed to near its potential yield at those places. The aquifer is used extensively in areas where the dissolved-solids concentration of the water is more than 500 mg/liter and in some places where the concentration exceeds 1 ,000 mg/liter. The most common water-quality problems are excessive chloride and fluoride. (Woodard-USGS)
