Developing Capacity for Local Watershed Management: Essential Leadership Skills and Training Approaches

Wolfson, L., A. Lewandowski, J. Bonnell, J. Frankenberger, F. Sleeper and J. Latimore. 2015.

Journal of Contemporary Water Research & Education 56:86-97.

Management of water resources at a watershed scale often occurs at the local level and relies on the effectiveness of local staff and leaders. Four land-grant universities in Indiana, Michigan, Minnesota and Ohio are delivering training programs that build the capacity of local water resource professionals.

Innovation Promoted by Regulatory Flexibility

Novak, P.J., W. A. Arnold, B. Henningsgaard, R. M. Hozalski, K. Kessler, T. L. LaPara, A. Parrella, L. Rogacki, C. Thompson,, R.Thorson, R.A. Zimmerman, C.B. Bott, G. T. Daigger, and J. B. Neethling. 2015.

Environmental Science & Technology

Humanity’s footprint, in terms of water use, water degradation, and resource consumption, is unsustainable.(1) In addition to changing behavior with respect to resource use, technical innovation is needed to reduce this footprint, enabling low energy water treatment and effective resource recovery. In research, there has been a push to stimulate/support new technology development, effective scale-up, and translation to application. These efforts are important for moving our society toward “sustainability,” where economic, social/societal, and environmental health are considered.

Quantification of Hydroxylated Polybrominated Diphenyl Ethers (OH-BDEs), Triclosan, and Related Compounds in Freshwater and Coastal Systems

Kerrigan, J.F., D. R. Engstrom, D. Yee, C. Sueper, P. R. Erickson, M. Grandbois, K. McNeill and W. A. Arnold. 2015

Hydroxylated polybrominated diphenyl ethers (OH-BDEs) are a new class of contaminants of emerging concern, but the relative roles of natural and anthropogenic sources remain uncertain. Polybrominated diphenyl ethers (PBDEs) are used as brominated flame retardants, and they are a potential source of OH-BDEs via oxidative transformations. OH-BDEs are also natural products in marine systems. In this study, OH-BDEs were measured in water and sediment of freshwater and coastal systems along with the anthropogenic wastewater-marker compound triclosan and its photoproduct dioxin, 2,8-dichlorodibenzo-p-dioxin.

Modeling the fate of antibiotic resistance genes and class 1 integrons during thermophilic anaerobic digestion of municipal wastewater solids

Burch, T. R., M.J. Sadowsky and T.M. LaPara. 2015

This study investigated the use of thermophilic anaerobic digestion for removing antibiotic resistance genes (ARGs) from residual municipal wastewater solids. Four laboratory-scale anaerobic digesters were operated in 8-day batch cycles at temperatures of 40, 56, 60, and 63 °C.

Assessing Iron-Enhanced Swales for Pollution Prevention

Natarajan, P. and J. Gulliver. 2015

The treatment of dissolved phosphorus and metals in runoff requires specialized filtration media, which, however, is not accounted for in the typical swale ditch check designs currently employed. In this project, ditch checks with iron-enhanced sand filter insert were developed to increase the retention of phosphate and dissolved metals in roadside swales and ditches.


Fields to Streams: Managing Water in Rural Landscapes is a web-based document available from University of Minnesota Extension. Land owners, land managers, and the conservation professionals who work with them have access to a new publication explaining how runoff shapes rural streams and describes land and water management practices that will improve and protect them. Increased stream flows are causing an increase in streambank, bluff, and ravine erosion, resulting in wider streams, and ravines and gullies that are extending into fields. Downstream, the sediment is filling lakes and degrading fish habitat. Fields to Streams shows ways land managers can reduce the rate of erosion and sediment loss.

Randy Pepin, UM Extension educator has been collaborating with Les Everett (WRC) on a P-balance 319 project and has published two articles in conjuction with that project in the magazine Dairy Herd Management:

Timely manure incorporation should be top 'poo' priority

Feed shrink - Economic loss and environmental impacts

Minnesota Pollution Control Agency’s monthly newsletter Waterfront Bulletin features updates on impaired waters, watershed project funding, and activities related to water restoration and protection throughout Minnesota.

Governor Mark Dayton's landmark buffer initiative was signed into law this year. The law establishes new perennial vegetation buffers of up to 50 feet along rivers, streams, and ditches that will help filter out phosphorus, nitrogen, and sediment. The new law provides flexibility and financial support for landowners to install and maintain buffers, and boost compliance with buffer laws across Minnesota. The DNR's role in Minnesota's new buffer law is to produce maps of public waters and ditch systems that require permanent vegetation buffers. The DNR is scheduled to produce these maps by July 2016.
