Minnesota Pollution Control Agency Wild Rice Sulfate Standard Field Study

Abstract: This study was undertaken by the Minnesota Pollution Control Agency (MPCA) and University of Minnesota to improve the understanding of why wild rice (Zizania palustris, manoomin, psin) is observed to thrive only in waters with low sulfate (SO4), and to contribute to evaluation of Minnesota Rules 7050.0224, promulgated in 1973, which seeks to limit the exposure of wild rice to sulfate concentrations exceeding 10 mg/L. The dataset is now released as manuscripts using it are being published.
