Yingxin Gu, Bruce K. Wylie
2017, GCB Bioenergy (9) 836-844
Growing cellulosic feedstock crops (e.g., switchgrass) for biofuel is more environmentally sustainable than corn-based ethanol. Specifically, this practice can reduce soil erosion and water quality impairment from pesticides and fertilizer, improve ecosystem services and sustainability (e.g., serve as carbon sinks), and minimize impacts on global food supplies. The main goal...
Pathogen transport in groundwater systems: Contrasts with traditional solute transport
Randall J. Hunt, William P. Johnson
2017, Hydrogeology Journal (25) 921-930
Water quality affects many aspects of water availability, from precluding use to societal perceptions of fit-for-purpose. Pathogen source and transport processes are drivers of water quality because they have been responsible for numerous outbreaks resulting in large economic losses due to illness and, in some cases, loss of life. Outbreaks...

Jianping Zhou, Hongmei Wang, Charles A. Cravotta III, Qiang Dong, Xing Xiang
2017, Geomicrobiology Journal (34) 421-433
Chemical weathering of fluorine-bearing minerals is widely accepted as the main mechanism for the release of fluorine (F) to groundwater. Here, we propose a potential mechanism of F release via microbial dissolution of fluorapatite (Ca5(PO4)3F), which has been neglected previously. Batch culture experiments were conducted at 30°C with a phosphate-solubilizing...
