Article Synopsis
- The Buffalo National River (BNR) in Arkansas is a significant water resource studied for its bacterial ecology, particularly in relation to nearby concentrated animal feed operations (CAFOs).
- Water sampling revealed that bacterial counts (CFUs) were highest near the CAFO, while esterase activity was surprisingly lower at these locations, suggesting a complex interaction with organic enrichment.
- Metagenomic analysis indicated that microbial diversity and activity were influenced by proximity to wastewater sources, and laboratory experiments confirmed that exposure to organic wastewater contaminants altered bacterial metabolism, particularly highlighting atrazine's negative impact.
Continuous monitoring data can be extremely useful for assessing water-quality conditions particularly for variables, such as dissolved oxygen, that exhibit dynamic diel swings. As a means of evaluating stream dissolved oxygen criteria used by the Arkansas Department of Environmental Quality (ADEQ), we compared continuous dissolved oxygen (DO) data collected at five small- to moderate-sized (watersheds 10-100 mi), high-gradient streams in the Boston Mountains distributed across a land-use and nutrient condition gradient. The sampled streams exhibit a general pattern established for other aquatic systems (e.
