Relationship Between Land-Use And Water Quality In Spring-Fed Streams Of The Ozark National Forest, A. Smartt, S. Ganguly, M. A. Evans-White, B. E. Haggard
Relationship Between Land-Use And Water Quality In Spring-Fed Streams Of The Ozark National Forest, A. Smartt, S. Ganguly, M. A. Evans-White, B. E. Haggard
Journal of the Arkansas Academy of Science
Spring-fed streams are abundant in karst topographic regions such as the Ozarks, providing an important and valuable water resource. Many of these spring-fed streams presently receive agriculture runoff, but few studies have examined the impacts of this runoff on water quality. We examined water quality in Ozark spring-fed streams surrounded by either agricultural (N=3) or primarily forested land (N=3) in the riparian zone. We hypothesized that agricultural sites would have greater dissolved nutrient concentrations and conductivity than forested sites and that water quality would fluctuate with distance from the spring source. Conductivity (p

An impervious surface is any surface that prevents water from infiltrating the ground. As impervious surface area increases within watersheds, stream networks and water quality are negatively impacted. The Multi-Resolution Land Characteristic Consortium developed a percent impervious dataset using Landsat imagery as part of the 2006 National Land Cover Database. This percent impervious dataset estimates imperviousness for each 30-meter cell in the land cover database. The percent impervious dataset permits study of impervious surfaces, can be used to identify impacted or critical areas, and allows for development of impact mitigation plans; however, the accuracy of this dataset is unknown. To …
Water Quality Assessment Of Sager Creek Utilizing Physiochemical Parameters And A Family-Level Biotic Index, T. S. Wakefield
Water Quality Assessment Of Sager Creek Utilizing Physiochemical Parameters And A Family-Level Biotic Index, T. S. Wakefield
Journal of the Arkansas Academy of Science
An annual rapid bioassessment and physiochemical survey of Sager Creek in Northwest Arkansas was conducted. Sager Creek is a first to second order stream that flows through the city of Siloam Springs, AR. Invertebrate collections and water samples were collected at three different reaches, with the most downstream reach being below the effluent of the Siloam Springs Wastewater Treatment Plant. Benthic arthropods were collected, identified, and counted to produce a family-level biotic index and a family-level index of diversity. Statistical analysis revealed that these indices were significantly different for the effluent- influenced reach. However, this difference could not be correlated …
