Jared Trost is a hydrologist with the Upper Midwest Water Science Center using field studies, innovative sampling equipment, statistics, and modeling to understand (1) the influences of land cover, contaminants, and unsaturated zone properties on the quality and quantity of water reaching unconfined aquifers and (2) surface-water/groundwater interactions.
Jared Trost is a hydrologist and has led several investigations on the influences of land cover, contaminants, and unsaturated zone properties on the quality and quantity of water reaching unconfined aquifers and the interactions of these groundwater systems with surface-water. He is presently the site coordinator for the USGS Toxic Substances Hydrology Program's Bemidji crude oil spill site and the chair of the Unsaturated Zone Interest Group (UZIG). In his capacities as the Bemidji crude oil spill site coordinator and chair of the Unsaturated Zone Interest Group (UZIG), he facilitates collaborative research and communication among scientists. Ongoing projects include:
- investigating the seasonal variability in crude oil degradation rates at a subsurface crude oil spill
- designing innovative field tools for sample collection and monitoring in soil and shallow groundwater
- investigating the effects of climate, groundwater withdrawals, and landscape properties on the stability of lake levels in glacial terrain
- estimating recharge to surficial glacial aquifers in the U.S. with the soil water balance (SWB) model
