Organic Matter Dynamics and Trophic Structure in Karst Groundwater
In this study of energy pathways in karst groundwater the first chapter examines spatial and temporal patterns of bacterial density and activity in the Dorvan-Cleyzieu karst aquifer, France. During baseflow, bacterial density and activity in the water column was similar in upper and lower zones of …

Agricultural Contaminant Source and Transport in a Karst Groundwater Basin
… land use in areas that are located in karst groundwater basins negatively impact groundwater quality because karst terrains provide multiple, direct hydrologic connections from the surface into karst aquifers. The connections and rapid velocities associated with surface and subsurface …

Estimating groundwater recharge in Jinci karst groundwater system, North China
More than 25% of the world’s population relies on karst groundwater as the primary source for drinking and irrigation. However, due to the global climate change as well as population expansion, the contradictory between supply and demand of water resource becomes more and more pronounced. Karst …

Lithologic Controls on Karst Groundwater Flow, Lost River Groundwater Basin, Warren County, Kentucky
<p>The Lost River Groundwater Drainage Basin in Warren County, Kentucky, is a karst drainage system encompassing 55 square miles (143 square kilometers) developed within the Mississippian St. Louis and Ste. Genevieve Limestones. Near the contact between these two formations are two bedded chert …

Water Quality Impacts from Agricultural Land-Use in the Karst Groundwater Basin of Qingmuguan, Chongqing, China
Karst regions are composed of soluble rock, often limestone, which leads to the formation of fissures, sinkholes and water flow conduits such as caves. Pollutants in karst waters tend to be quickly directed and concentrated into these subsurface conduits. As a result of this and other factors, …

Geographic Information System Methodologies to Evaluate Relationships Between Land use and Groundwater Quality in South Central Kentucky
… for a holistic approach to the study of karst groundwater contamination. While karst groundwaters supply water to a large percentage of the earth's population, its complex environments often have lacked the scientific examination and conservation measures typical of non-karst regions. In …

Identification of fecal pollution sources of karst waters by a combination of Bacteroidales genetic marker, bacterial indicators, and environmental variables
Fecal contamination in Midwestern karst regions was evaluated by a combination of Bacteroidales-based microbial source tracking (MST), traditional bacterial indicators, and environmental variables. Water samples from springs and wells were collected from Illinois, Wisconsin, Kentucky and Missouri …
