Water Quality Monitoring
Utilizing three state funding sources, we have three total nitrogen and total phosphorus water sampling programs.
Tile Drain Study
Funding Source: Sub Contract with the Franklin County Conservation District.
The goal of this sampling program to is inform Vermont regulations and recommendations for best management practices related to tile drainage in agricultural fields. Sampling started summer of 2018 and is happening all around the state. Orleans County NRCD staff samples Total Nitrogen and Total Phosphorus at two farms at four sites total, every two weeks and two rain events annually.
Memphremagog Tributary Monitoring
Funding Source: NRCC Basin Planning
This sampling program is done to monitor the phosphorus loading from the four main drainages to lake Memphremagog. This monitoring program has been ongoing since 2005 and is used to evaluate changes in phosphorus loading in relation to reduction targets in the Lake Memphremagog TMDL OCNRCD staff take 13 high flow event samples annually. A high flow is when Black River stream gauge is above 500cfs. Regular monthly sampling at all the same four sites is done by the VTDEC Basin Planner.
Agricultural BMP Monitoring
Funding Source: VAAFM Clean Water Program and LaRosa Organizational Grant and LaRosa Analytical Grant
Orleans County NRCD Staff sample eight dates from April to October with at least two rain events. The goal of this sampling program is to evaluate pre and post BMP water sampling results to document the phosphorus and nitrogen nutrient pollution sources and assessing the effectiveness of water quality remediation practices on agricultural landbases. Seven of the nine farms we are evaluating are RCPP program cooperators.
