Sparta Aquifer Recovery Project Wells Map - Arkansas
Date Published: July 5, 2017

Sparta Aquifer Recovery Project

The Sparta aquifer is Union County's only source of municipal and industrial ground water. Since development began in the early 1920's ground-water levels have declined more than 390 feet in some areas. As a result, Union was among five southern Arkansas counties designated as the state's first "Critical Ground Water Area" in 1996.

Contaminants in linked aquatic–terrestrial ecosystems: Predicting effects of aquatic pollution on adult aquatic insects and terrestrial insectivores

Organisms that move across ecosystem boundaries connect food webs in apparently disparate locations. As part of their life cycle, aquatic insects transition from aquatic larvae to terrestrial adults, thereby linking freshwater ecosystem processes and terrestrial insectivore dynamics. These linkages are strongly affected by contamination of...
