In urban and suburban areas, much of the land surface is covered by “impervious surface”—buildings and pavement that prevent rain from soaking into the ground. Large amounts of this runoff are directed into storm drains that carry it into nearby waterways. Unfortunately, runoff can also carry pollutants such as oil, dirt, chemicals, and lawn fertilizers directly into streams and rivers.

Estimates of forest soil organic carbon stocks across the US are currently developed from expert opinion in STATSGO/SSURGO and linked to forest type. The results are reported to the US EPA as the official United States submission to the UN Framework Convention on Climate Change. Beginning in 2015, however, estimates of soil organic carbon (SOC) stocks will be based on SOC data from soil cores collected in the field (0-10 and 10-20 cm depth). In addition, the Intergovernmental Panel on Climate Change (IPCC) Good Practice Guidance suggests these estimates extend to at least 30 cm for all forested lands. This study reports the results of that extrapolation effort.

The occurrence and spatiotemporal variation of 26 contaminants of emerging concern (CECs) were evaluated in 68 water samples in 2011–2012 in the Zumbro River watershed, Minnesota, U.S.A. Samples were collected across a range of seasonal/hydrological conditions from four stream sites that varied in associated land use and presence of an upstream wastewater treatment plant (WWTP).

The prairie pothole region (PPR) spans more than 750,000 km2 in central North America and is densely populated with wetlands and ephemeral lakes that form essential habitats in the many, often shallow, depressions of the landscape. Little surface connectivity exists between individual water bodies, but slow depression focused groundwater flow through pyrite and gypsum rich glacial until connects PPR wetlands.

Groundwater concentrations of residual crude oil metabolites exceed concentrations of diesel range organics, yet are largely unmonitored.
Now available at UM Bookstore: Fields to Streams: Managing Water in Rural Landscapes is a available from University of Minnesota ExtensionEither as a download or in softcopy form the UM Bookstore. 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.
