An Ecological Assessment of Restoration Efforts Developed to Recover an Intensively Mined Appalachian Watershed
… ecological recovery of acid mine drainage (AMD) impaired streams. We sampled water chemistry, physical habitat, and benthic macroinvertebrate and fish community structure in 3 stream types: AMD (14 streams), AMD-treated (13 streams), and unimpaired reference (4 streams). Treatment technology …

The Effects of Nutrient Concentrations on Macroinvertebrate Distributions in Georgia
… in low amounts and are typically increased in streams as a result of industry, agriculture, silviculture, and urbanization. In large amounts, nutrients can cause many problems to occur in the stream ecosystem. Macroinvertebrates have been established as good indicators for determining the level …

A Cost Effective Approach to Taxonomic Resolution For Bioassessment and Monitoring Programs in the State of Georgia
… Project has developed biological criteria for streams in Georgia according to the Rapid Bioassessment Protocols For Wadeable Streams and Rivers. Streams will ultimately be classified into categories of impairment so that management decisions can be made in accordance with the Clean Water Act. A …

Stratification of Southern Georgia Streams For Rapid Bioassessment Focusing on Differences in Structure and Function of Black Water and Clear Water Streams
… project for the state of Georgia, relatively unimpaired reference streams and impaired sites were sampled for biological, chemical and physical parameters, and macroinvertebrates were identified. The metrics, biological, physical and chemical metrics, were selected using Ecological Data …

Reframing the Ditch
… plan to improve water quality of their impaired streams. Water quality impairment is often exacerbated when headwater streams flow through urban areas. Urban areas are concentrations of human activity and as such bring concentrations of impermeable surfaces and stormwater runoff. As …

Modeling Fecal Indicator Bacteria and Antibiotic Resistance in Diverse Aquatic Environments
… them can be crucial to reducing the number of impaired streams and limiting the negative impacts on the environment. Antibiotic resistance is an emerging issue facing human health in the United States and across the world. Antibiotic resistant bacteria (ARB) have antibiotic resistance genes …

Chironomidae Contributions to the Macroinvertebrate Assemblage, Index of Biotic Integrity and Relationships to Water Quality Impairment for Eastern South Dakota Streams
… explored extensively from wadeable perennial streams of the Northern Glaciated Plains (NGP). Moreover, no effort has been attempted to develop a multimetric index of biotic integrity (IBI) using Chironomidae larvae. The objectives of this research were to (1) assess the contribution of …

An Investigation of the Relationships Between Stream Benthic Macroinvertebrate Assemblage Conditions and Their Stressors
… decreased water quality, and ultimately impaired benthic macroinvertebrate assemblage conditions. In streams where the benthic macroinvertebrates are impaired, the stream itself will not be meeting the water quality standards set forth in the Clean Water Act. As a result, the goal of this …
