Mark Brigham is a Scientis Emeritus with the Upper Midwest Water Science Center.
I received a B.A. in Chemistry and an M.S. in Civil Engineering, both from the University of Minnesota. My Master’s thesis research examined historical patterns of mercury deposition using lake sediment cores, and other aspects of aquatic mercury cycling. I joined the U.S. Geological Survey in 1991, and worked for several years assessing water quality in the Red River of the North Basin. I then shifted back to mercury, examining methylmercury occurrence in impoundments and other waters of the Red River Basin; small lakes in Voyageurs National Park; streams in the St. Croix River Basin; coordinated mercury studies for the U.S. Geological Survey’s National Water-Quality Assessment Program; and examined trends in wet deposition of mercury across the U.S.
September 2018 – present: Supervisory Hydrologist, Upper Midwest Water Science Center, Mounds View, MN.
July 2016 – September 2018: Supervisory Hydrologist and Section Chief, Investigations Section, U.S. Geological Survey, Minnesota Water Science Center. Direct water resources investigations program with a total budget of over $4 million. Review schedules, work plans, budgets, and priorities of staff within the section; meet with State and local agency officials; and supervise senior hydrologists and Team Leads within the section.
January 2016 – July 2016: acting Section Chief, Investigations Section, U.S. Geological Survey, Minnesota Water Science Center.
2013-2016: Hydrologist, U.S. Geological Survey, Minnesota Water Science Center. Working on variety of water-resources projects, including trend analysis of mercury in Voyageurs National Park.
2001-2013: Hydrologist, U.S. Geological Survey, Minnesota Water Science Center, and coordinator for Mercury in Stream Ecosystems studies for the National Water-Quality Assessment program. Responsible for coordinating collaborative team of internal (USGS) and external scientists; development of study objectives; study design (including water-quality sampling design and quality assurance program); and communicating results through publication of interpretive reports and presentations to diverse audiences.
1991-2001: Environmental Engineer, U.S. Geological Survey, Minnesota Water Science Center. Studied mercury and methylmercury levels in flood-control impoundments and natural waters; and sediment sources to a stream in an agricultural basin. Both studies are in the Red River of the North Basin. From 1999-2001 I was a member of National water-quality users group, reviewing implementation of the World Wide Web interface to the USGS water-quality data base. From 1991-97, worked on Red River of the North National Water Quality Assessment project. Water-quality specialist on a multidisciplinary team (surface-water, ground-water, and aquatic biology). Study focused on human effects on water quality, especially nutrients and pesticides in water
