Mass Flux Of Agricultural Nonpoint-Source Pollutants In A Conduit-Flow-Dominated Karst Aquifer, Logan County, Kentucky, James C. Currens Jan 1999

Mass Flux Of Agricultural Nonpoint-Source Pollutants In A Conduit-Flow-Dominated Karst Aquifer, Logan County, Kentucky, James C. Currens

Report of Investigations--KGS

Changes in water quality in a karst ground-water basin used intensively for agriculture are being measured before, during, and after the implementation of best management practices (BMP’s) and other management practices, to determine the success of such programs in protecting ground water. The study was divided into three phases. The results of the first two phases are included in this report and cover research conducted between August 1990 and October 1994. During phase I of the study the overall ground-water quality of the basin and its hydrogeology were investigated. Phase II began monitoring the water quality at Pleasant Grove Spring …


Tectonic Implications Of Erosional And Depositional Features In Upper Meramecian And Lower Chesterian (Mississippian) Rocks Of South-Central And East-Central Kentucky, Garland R. Dever Jr. Jan 1999

Tectonic Implications Of Erosional And Depositional Features In Upper Meramecian And Lower Chesterian (Mississippian) Rocks Of South-Central And East-Central Kentucky, Garland R. Dever Jr.

Bulletin--KGS

Erosional and depositional features in upper Meramecian and lower Chesterian (Mississippian) carbonate rocks of south-central and east-central Kentucky suggest the influence of coeval structural activity. The study area, which extends from Pulaski County northeastward into Powell County, is underlain by (1) the Greenwood Anomaly, a large north-trending gravity anomaly, which probably represents part of a Precambrian rift system, and (2) the western part of the Rome Trough, an east-trending graben-like structure, which represents a Late Precambrian to Cambrian continental rift zone. The study focused on the St. Louis Limestone and lower Monteagle Limestone of south-central Kentucky and correlative carbonate rocks …

Information Circular--KGS

Fluoride (F-) is an ion of the element fluorine, and is a natural component in most water resources. According to Hem (1989), fluoride concentrations in fresh water are generally less than 1 mg/L (milligrams per liter), and the concentration of fluoride in the world's oceans is about 1.3 mg/L. The source of most fluoride in natural fresh-water resources is various rocks and minerals in bedrock and sediments.
