My research, teaching and service focus on the conservation and restoration of watersheds. I’ve researched herbicides, heavy metals, nutrients, nuisance algae, and other water quality issues for EPA, US Geological Survey, Forest Service, NRCS, the state of Montana & local government agencies. I helped the Montana Department of Environmental Quality develop a statewide water quality monitoring system and water quality criteria through studies of streams and lakes throughout Montana. Our work on wadeable streams in the Northern Plains and Western Mountains appears in a recent
EPA report. As part of a team of scientists, I helped EPA develop
nutrient criteria guidance documents for the US.
Much of my work focuses on western Montana's Clark Fork River Basin which contains wilderness, working lands, and the largest Superfund complex in the country. I helped the state of Montana design and interpret a basin-wide water quality study of this basin, and I continue to assist the
Tristate Water Quality Council with monitoring and management of this basin. With a colleague, I developed a
watershed information delivery system and have organized and edited a series of
Clark Fork Symposia where citizens and scientists discuss the science and conservation of the basin. While serving as PI or Co-PI on well over $1 million in grants over the past 20 years, I also provided countless hours of pro bono assistance to community groups.
