USDA Water Quality Demonstration Project

Prepared by: Frank J. Humenik

Long-Term Objectives

1. Implementation of agricultural best management practices to protect and enhance surface and ground water quality.

2. Conduct ground water sampling to determine changes in nitrate level.

3. Monitor surface water and track land use to make correlations between BMP implementation and water quality changes.


Short-Term Objectives

1. Establish state and local planning committee.

2. Develop information and education program.

3. Determine type and location of BMPs which have been implemented.

4. Encourage producers to implement recommended BMPs.


Accomplishments

1. Beaver dam that provided an enhanced in-stream wetland resulted in reduction of nitrate nitrogen from about 5-7 mg/1 to 1 mg/1 during the summer.

2. A state-of-the-art mortality management system for composting dead turkeys and litter has operated very successfully.

3. Ground water concentrations of nitrate have been reduced and nitrogen and phosphorus at the watershed outlet have shown a downward tread over the last two years.


Significance of Accomplishments

Surface and ground water monitoring has documented reduced nitrogen and phosphorus concentrations at sites with implemented BMPs and at the outlet of the study watershed. This documents water quality benefits from implemented BMPs and in-stream wetland.


Future Plans

1. Continue to encourage management and implementation of BMPs, land use tracking and water quality monitoring to document water quality benefits and to provide data for model development, calibration and validation.
