A three year study was conducted to determine the effects of agricultural drainage and development on hydrology and runoff water quality on high organic soils in the North Carolina Tidewater Region. Experiments were conducted on paired developed and undeveloped sites of three different soils that span the range of soils being developed in the Tidewater Region. Each of the six sites (three developed, three undeveloped) were instrumented to continuously measure the rate of runoff, to sample for water quality and pesticide analyses, and to determine other variables such as rainfall and water table depth. Peak runoff rates occur earlier and are three to four times higher on developed than on similiar undeveloped lands. One potential water quality problem is the movement of fecal organisms from grazed pastures into drainage water.
