Streamflow conditions, and trends thereof, are critical drivers of all aspects of stream geomorphology, sediment and nutrient transport, and ecology. Using the non-parametric Mann-Kendall test, we analyzed annual streamflow trends from 1996 to 2021 for the Southern Appalachian region. The forested highlands receive high amounts of rain and act as a “water tower” for the […]
Drinking water infrastructure in homes and buildings provides a niche for water microbiomes. Higher surface area to volume ratios, stagnation, and disinfectant decay at point-of-use locations lead to microbial regrowth and a higher risk of exposure to opportunistic premise plumbing pathogens (OPPPs). Nitrifying bacteria are common inhabitants of drinking water systems and are known to […]
Wastewater reuse benefit water shortage and a variety purposes but effect to water quality of receiving body is a concern, especially when effluent of sewage treatment plant is introduced to source of drinking water facility. Indirect potable reclamation characterized as mixing effluent into either surface or groundwater source, subsequently flowing into drinking water treatment plant, […]
