Interpretive Summary: A woodchip bioreactor is a practice that removes nitrate as water flows through the bed. Bromide is a common tracer used to study and optimize flow. This data in brief paper contains measurements from laboratory and field experiments using bromide. The laboratory experiment results include values of bromide retention in ground, unwashed, and washed woodchips. The field experiment results document bromide concentration versus time for tests on seven woodchip beds in West Central Minnesota. The data in this paper have been interpreted in a previous publication, “Efficacy of bromide tracers for evaluating the hydraulic performance of denitrification beds treating agricultural drainage water.” The information is pertinent to researchers, engineers, academics, and agency personnel for guidance in conducting tracer tests and investigating hydraulic performance of woodchip beds.

Technical Abstract: Three different woodchip forms were tested for bromide sorption including ground woodchip, unwashed woodchips, and washed woodchips. We used six varying initial bromide concentrations to conduct the bromide sorption experiments with each woodchip form. Data on the initial and equilibrium bromide concentrations, wood mass, and initial and equilibrium solution pH from each of the six experiments are presented. Seven bromide tracer tests were conducted on field-scale denitrification beds. In this paper, data of from each of the tracer tests including variation of bromide concentration over time and hydraulic indices of the tracer tests are presented. Interpretation of the data can be found in the research article entitled "Efficacy of bromide tracers for evaluating the hydraulic performance of denitrification beds treating agricultural drainage water."
