The geology of Alabama is marked by abundant geologic resources and a variety of geologic structures from folded mountains in the north to sandy beaches along the Gulf of Mexico coast. Alabama spans three continental geologic provinces as defined by the United States Geological Survey, the Atlantic Plain, Appalachian Highlands, and Interior Plains.
From 2008 to 2010 the United States Geological Surveys' Alabama and South Carolina Water Science Centers conducted tests on numerous things in and around the site of the plume in downtown Montgomery. Contaminants had been found in groundwater, so the tests were conducted to reveal where the source of contamination was stemming from as well as ...
This map of United States water resource subregion hydrologic units updated boundaries to include the ocean as well as the portions of the basins that cross international borders For the use of hydrologists, ecologists, and water-resource managers in the study of surface water flows in the United States, the United States Geological Survey ...
The Flint River, 65.7 mi (105.7 km) long [3] and draining an area of 568 sq mi (1,470 km 2), is a tributary to the Tennessee River.The river rises in Lincoln County, Tennessee, and flows south into Madison County, Alabama, where most of the river's watershed (342 sq. mi.) is located.
According to the US Geological Survey, there are 5 steps to manual watershed delineation: [6] Find the point of interest along a stream on the map. This is the "watershed outlet" or "pour point." Imagine or draw surface water flow lines that point downhill perpendicular to the topographic contours (this is the steepest direction).
Alabama Water Watch is dedicated to volunteer citizen monitoring of water quality in Alabama Rivers. [ 20 ] The Presbytery of Sheppards and Lapsley , the regional governing body for the Presbyterian Church (USA) in central Alabama, is developing a camp and conference center on the Cahaba River called Living River.

[4] [5] The United States Geological Survey reported in 2023 that at least 45% of drinking water in the United States contains per- and polyfluoroalkyl substances (PFAS), commonly referred to as "forever chemicals." [6] [7] The EPA has been able to identify around 70,000 water bodies that do not meet revised water quality standards due to PFAS. [2]
