The U.S. Geological Survey provides a wide range of scientific information to an even wider group of stakeholders. Understanding what capacities are needed and if and or where these capacities exist across the USGS landscape is critical in moving science to the next level of use, implementation, and visualization. The concept behind the groups organized to conduct and interpret the survey that collected these data took advantage of the USGS’s position as a science organization with expertise spanning a wide range of science disciplines, stakeholders, and responsibilities. A survey was conducted of USGS employees (Sep 20-Nov 20) to get a current sample of the capacities that exist across the USGS.

Historic mining activity in the Old Lead Belt has led to substantial influx of lead and zinc mining waste into the channel of the Big River in southeastern Missouri. The primary objectives of this data collection was to determine the depth of heavy-metal contamination at five gravel bars along the Big River to verify and supplement findings by Pavlowsky and Owen (2010). A secondary objective of the study was to develop and implement methods for use in other Natural Resource Damage Assessment projects, such as the Tri-State Mining District (TSMD) project (Smith, 2016). This data was collected in cooperation with the Ozarks Environmental and Water Resources Institute, Missouri State University, and U.S. Fish and Wildlife...

The existing three-dimensional groundwater flow model (MODFLOW-2005) of the Mississippi Embayment Regional Aquifer system (MERAS), South-Central United States, was updated with: 1) higher stream density; 2) more spatially refined recharge; 3) better estimates of water use; 4) more recent time period simulated; 5) more realistic storage conceptualization; and 6) more robust handling of dry nodes through use of MODFLOW-NWT. For this study, the MODFLOW-NWT groundwater flow model was used to evaluate four parameter estimation algorithms with lower computational burdens. This work was performed to update the previous version of the MERAS groundwater flow model for decision making in the Mississippi Alluvial Plain (MAP),...
