Generalized Geologic Map For Land-Use Planning: Laurel County, Kentucky, Daniel I. Carey, John Storm Jan 2007

Generalized Geologic Map For Land-Use Planning: Laurel County, Kentucky, Daniel I. Carey, John Storm

Map and Chart--KGS

This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.

Regional Groundwater Quality In Watersheds Of The Upper Cumberland, Lower Cumberland, And Lower Tennessee Rivers, And The Jackson Purchase Region (Kentucky Basin Management Unit 3), R. Stephen Fisher, Bart Davidson, Peter T. Goodmann

Report of Investigations--KGS

The Kentucky Geological Survey and the Kentucky Division of Water are evaluating groundwater quality throughout the commonwealth to determine regional conditions, assess impacts of nonpoint-source contaminants, provide a baseline for tracking changes, and provide essential information for environmental-protection and resource-management decisions. This report summarizes expanded groundwater monitoring activities and groundwater quality in watersheds of the Upper Cumberland River, Lower Cumberland River, Tennessee River, and the Jackson Purchase Region (Kentucky Basin Management Unit 3).

Thirty wells and springs were sampled seasonally between the summer of 2000 and the spring of 2001, and analyzed at the Kentucky Division of Environmental Services Laboratory. …

Groundwater Quality In Kentucky: Barium, Bart Davidson, R. Stephen Fisher Jan 2006

Groundwater Quality In Kentucky: Barium, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Barium is a silver-white alkaline earth metal that is not found free in nature because it is highly reactive with sulfate and carbonate. Barium compounds can be naturally occurring or man-made. The most common natural occurrence of barium is in the mineral barite (barium sulfate), which has many uses in industry, such as a filler in the making of rubber, plastic and resin, white pigment, drilling lubricants used in the oil and gas industry, paint, bricks and glass (Agency for Toxic Substances and Disease Registry, 2004). Barium sulfate is very slightly soluble in water and absorbs X-rays, making it an …

Groundwater Quality In Kentucky: Mercury, Bart Davidson, R. Stephen Fisher Jan 2005

Groundwater Quality In Kentucky: Mercury, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Mercury is a naturally occurring metal that occurs in trace amounts in water, soils, and rocks. Elemental mercury is a liquid that occurs in some ore deposits; it may also be concentrated around hot springs. Currently, about 50 percent of mercury use is for electrical products such as dry-cell batteries, fluorescent lights, switches, and other control equipment. Mercury is also used in the electrolytic preparation of chlorine gas and caustic soda, and in paint manufacture and pesticide production (U.S. Environmental Protection Agency, 2002). In the past, significant amounts of mercury were used in thermometers and pressure gauges.


Groundwater Quality In Kentucky: Selenium, Bart Davidson, R. Stephen Fisher Jan 2005

Groundwater Quality In Kentucky: Selenium, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Selenium is a naturally occurring element found in most rocks and soils (Agency for Toxic Substances and Disease Registry, 2003). In its solid form, selenium is black, gray, or red and is odorless (New Jersey Department of Health and Senior Services, 2002). Most selenium is obtained from byproducts of the copper refining industry. Selenium compounds are often used in electronic components, photocopiers, metal alloys, rubber, paint pigments, glass-making (ruby red glass), and photographic emulsions (U.S. Environmental Protection Agency, 2003). Selenium exhibits both photovoltaic and photoconductive properties. As more light shines on selenium, its electrical conductivity increases, making it extremely useful …

Groundwater Quality In Kentucky: Cadmium, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Cadmium is a metallic element that occurs naturally in the earth's crust, especially in zinc-, lead-, and copper-bearing ores (Forstner and Whittmann, 1981). Pure cadmium is a soft silver-white metal, but is rarely found naturally in its pure form. It is commonly combined with other elements, such as oxygen (cadmium oxide) and sulfur (cadmium sulfate).

Changes In Groundwater Quality In A Conduit-Flow-Dominated Karst Aquifer As A Result Of Best Management Practices, James C. Currens Jan 2005

Changes In Groundwater Quality In A Conduit-Flow-Dominated Karst Aquifer As A Result Of Best Management Practices, James C. Currens

Report of Investigations--KGS

Water quality in the Pleasant Grove Spring karst groundwater basin was monitored to determine the effectiveness of best management practices (BMP’s) implemented through the U.S. Department of Agriculture’s Water Quality Incentive Program (WQIP). The project was divided into three phases. Phase I, beginning in August 1990, was the initial reconnaissance of the hydrogeology and water quality of the basin. Phase II, beginning in October 1993, monitored the water quality for 1 year prior to BMP implementation. This phase was followed by a 1-year interim extension, which continued the monitoring. Phase III monitored the water quality during and following BMP implementation. …

Groundwater Quality In Kentucky: Arsenic, R. Stephen Fisher Jan 2002

Groundwater Quality In Kentucky: Arsenic, R. Stephen Fisher

Information Circular--KGS

Arsenic is a naturally occurring element found in low concentrations in rocks, soils, water, plants, and animals (Nriagu, 1994 a, b). In Kentucky, arsenic is commonly found in iron sulfide minerals associated with coal deposits and black shales. Arsenic is released when iron sulfides oxidize during weathering. Once released, it is readily sorbed onto iron oxides and iron oxyhydroxides, which limits arsenic concentrations in the near-surface environment.


Groundwater Quality In Kentucky: Ph, R. Stephen Fisher Jan 2002

Groundwater Quality In Kentucky: Ph, R. Stephen Fisher

Information Circular--KGS

The parameter pH (the negative base-10 logarithm of hydrogen ion activity, measured in moles per liter) indicates whether a substance will behave as an acid or base. It is one of the most important parameters that describe groundwater quality, because pH largely controls the amount and chemical form of many organic and inorganic solutes in groundwater.

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 …


Ground-Water Quality In Kentucky: Fluoride, Philip G. Conrad, Daniel I. Carey, James S. Webb, James S. Dinger, R. Stephen Fisher, Matthew J. Mccourt Jan 1999

Ground-Water Quality In Kentucky: Fluoride, Philip G. Conrad, Daniel I. Carey, James S. Webb, James S. Dinger, R. Stephen Fisher, Matthew J. Mccourt

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.
