Researchers seek funding to integrate chemical monitoring with toxicity data and to pilot DNA‑based bioassessments
Summary
Two University of Minnesota teams told the LCCMR they want funding to (1) merge decades of ‘contaminants of emerging concern’ chemistry data with new toxicity datasets and build a public dashboard, and (2) test DNA‑based methods to improve aquatic macroinvertebrate bioassessments used to detect impaired waters.
Two separate research proposals on June 27 outlined plans to modernize how Minnesota evaluates water quality.
Dalma Martinovich Weigelt of the University of Minnesota presented a proposal to integrate Minnesota’s extensive two‑decade chemical monitoring for contaminants of emerging concern (CECs) with new toxicity data sets and to build an online dashboard for managers and the public. “These comparisons of chemical concentrations in water with the concentrations that cause toxicities are absolutely essential for identifying chemicals that impair water quality,” she told…
