Unconventional oil and gas development (UOG) generates high volumes of flowback and produced water, byproducts of hydraulic fracturing operations, that are often released or spilled on the soil surface. Soil contamination with these wastewaters, commonly referred to as brine, has the potential to inhibit vegetation growth indefinitely. Natural attenuation of brine is not expedient in arid and semi-arid regions where most United States UOG developments are located, including the Bakken region of North Dakota.

- The study examined how traffic from shale petroleum development affects dust exposure in rural landscapes, specifically in the Bakken region.
- Dust deposition was significant up to 180 meters from unpaved roads, yet it did not impact the abundance or behavior of birds and invertebrates in agricultural areas.
- The results indicate that wildlife in intensified agricultural environments can withstand additional disturbances from energy development, unlike species in undisturbed habitats.
We compare subsurface-drainage NO-N and total reactive phosphorus (TRP) concentrations and yields of select bioenergy cropping systems and their rotational phases. Cropping systems evaluated were grain-harvested corn-soybean rotations, grain- and stover-harvested continuous corn systems with and without a cover crop, and annually harvested reconstructed prairies with and without the addition of N fertilizer in an Iowa field. Drainage was monitored when soils were unfrozen during 2010 through 2013.
