The U.S. Department of Agriculture Natural Resources Conservation Service (NRCS) provides funding and technical assistance for the implementation of practices that enable people to conserve, maintain, or improve soil, water, and related natural resources. NRCS conservation practices, or best management practices, relate the conservation practices to conservation practice physical effects (CPPE). Physical effects are listed in the data and purpose and include effects such as nutrients and pesticides transported to surface and/or groundwater. The CPPE is published in the NRCS Field Office Technical Guide and is listed in the sources section. NRCS's CPPE includes a limited set of practices. All practices that do not...

Description of Work The Great Lakes Restoration Initiative (GLRI) was established to accelerate ecosystem restoration in the Great Lakes by confronting the most serious threats to the region, such as nonpoint source pollution, toxic sediments, and invasive species. Three Priority Watersheds have been targeted by the Regional Working Group's Phosphorus Reduction Work Group (Fox/Green Bay, Saginaw, and Maumee) and are characterized by having a high density of agricultural land use and have ecosystem impairments that have been clearly identified. Within the Maumee River Priority Watersheds, monitoring is being conducted at the sub-watershed, edge-of-field, and subsurface-tile scale. The edge-of-field and subsurface-tile...

Data were collected associated with the application of a pesticide to a stormwater retention pond and burrows to suppress or eradicate an invasive crayfish species, Procambarus clarkii, in support of high-priority research developing control methods to mitigate impacts of invasive crayfish within the Great Lakes Basin. Effectiveness of the treatment was accessed using an in-situ bioassay and by measuring pesticide concentrations in water, sediment, and caged crayfish. Water quality data, including temperature, pH, specific conductance, dissolved oxygen, alkalinity, hardness, ammonia, and turbidity, in stormwater ponds was collected to evaluate whether environmental conditions may impact treatment effectiveness and...
During the second half of the 1990’s Coal Bed Methane (CBM) production increased dramatically nationwide to represent a significant new source of natural gas. In recent years, the exploration and development of CBM has been under intense scrutiny in many parts of the country. The heightened concern of environmental issues related to present-day production practices - including water production, hydraulic fracturing, pipeline construction, storage facilities, water impoundment and disposal facilities, underground injection activities, compressor station operations, etc. – increases the importance of using practices and mitigation strategies that facilitate resource development in an effective, timely, and environmentally...
Congresswoman Dianna DeGette of Colorado recently introduced legislation that would again place hydraulic fracturing under the federal Safe Drinking water Act and thereby under the jurisdiction of the U.S. EPA. (House Bill H.R. 7231) Further, the issue of hydraulic fracturing is again receiving publicity. The November 2008 edition of Business Week addresses hydraulic fracturing. The State of Alabama and the IOGCC have addressed the issue extensively. In this paper, we will review the history of litigation concerning hydraulic fracturing.
Anthropogenic activities such as agricultural practices can have large effects on the ecological components and overall health of stream ecosystems. Therefore, having a better understanding of those effects and relationships allows for better design of mitigating strategies. The objectives of this study were to identify influential stream variables that correlate with macroinvertebrate indices using biophysical and statistical models. The models developed were later used to evaluate the impact of three agricultural management practices on stream integrity. Our study began with the development of a high-resolution watershed model for the Saginaw River watershed in Michigan for generating in-stream water quality and...
The microbiology of stream water has a seasonal component that results from both biogeochemical and anthropogenic processes. Analysis of nonevent conditions in streams entering Conesus Lake, NY (USA), indicated that total coliform, Escherichia coli, and Enterococcus spp. levels peak in the summer in all streams, independent of the agricultural use in the stream sub-watershed. Prior to implementation of management practices, E. coli in water draining Graywood Gully, a sub-watershed with 74% of the land in agriculture, reached as high as 2806 CFU/100 mL, exceeding the 235 CFU/100 mL EPA Designated Bathing Beach Standard (EPA-DBBS). In contrast, North McMillan Creek, a sub-watershed with < 13% of its land in agriculture,...
