Groundwater age distributions and susceptibility to natural and anthropogenic contaminants were assessed for selected wells, streambed piezometers, and springs in southeastern Minnesota. The data provide information to understand how long it will take to observe groundwater quality improvements from best management practices implemented at land surface to reduce losses of nitrate (and other chemicals) from agricultural practices. Nineteen water samples were collected from ten wells, three streambed piezometers, and four springs between August 2020 and September 2022. Two of these samples are field replicate samples collected from a spring site and a well site. A child item contains historical data from 15 water...

Confined (or buried) aquifers overlain by till confining units are used to supply drinking water to millions of people. Till confining units are typically conceptualized as having very low potential for transmitting water. Thus, buried aquifers are thought to be less susceptible to surface contamination, but may recharge very slowly and may be prone to unsustainable groundwater withdrawals. Quantification of the recharge (leakage) rate through till is essential to understanding the long-term sustainability of groundwater withdrawals from buried aquifers and yet few data exist on the hydraulic properties of till and groundwater flux through till. The information contained in this data release is generated from field...

The dataset consists of 30-year percentage depletion calculations, hydrocarbon group compositions, organic carbon mass fractions and hydrocarbon concentrations for 16 locations sampled at the Bemidji (MN) oil spill study site. Also included in the dataset are concentrations for 33 individual volatile hydrocarbons from the aforementioned sampling locations.

This U.S. Geological Survey data release provides detailed sampling site information, hole and well construction details, and data dictionaries necessary to interpret historical and future physical, chemical, and biological data sets derived from samples collected and measurements made in association with the National Crude Oil Spill Fate and Natural Attenuation Research Site. In 1979, a high-pressure pipeline carrying crude oil burst near the city of Bemidji, Minnesota and spilled approximately 1.7 million liters (10,700 barrels) of crude oil into glacial outwash deposits (Essaid and others, 2011). Since 1983, scientists with the U.S. Geological Survey, in collaboration with scientists from academic institutions,...
