Summary
Note: This data release is currently being revised and is temporarily unavailable. Mercury (Hg) concentrations and isotopic compositions were collected in sediments, soils, and suspended particulate matter from Gruber's Grove Bay (GGB) and upstream reference sites to inform future remedial efforts. The highest concentrations and isotopic signatures (δ202Hg) were observed in soils collected from historic water settling ponds from the Badger Army Ammunition Plant (BAAP). Sediments from the upper portion of GGB showed higher isotopic compositions than sediments from the Wisconsin River. Hg concentrations in sediments were also higher in the upper portion of GGB and decreased towards the river. Sediments collected from the GGB margin [...]
Summary

Mercury (Hg) concentrations and isotopic compositions were collected in sediments, soils, and suspended particulate matter from Gruber's Grove Bay (GGB) and upstream reference sites to inform future remedial efforts. The highest concentrations and isotopic signatures (δ202Hg) were observed in soils collected from historic water settling ponds from the Badger Army Ammunition Plant (BAAP). Sediments from the upper portion of GGB showed higher isotopic compositions than sediments from the Wisconsin River. Hg concentrations in sediments were also higher in the upper portion of GGB and decreased towards the river. Sediments collected from the GGB margin (the confluence with the Wisconsin River) were within the concentration and isotopic ranges of Weigand's Bay and further upstream sites. Suspended particulate matter collected from the Wisconsin River and GGB site were isotopically similar to particulate matter from upstream and reference sites.

Data were collected to assess mercury (Hg) concentrations and isotopic compositions at Gruber's Grove Bay (GGB), Wisconsin for future management decisions related to the site. Sediments, soils, and suspended particulate matter were collected for Hg analysis from regions of GGB and upstream sites with no known Hg discharge (Weigand's Bay and Lake Wisconsin). These data will be provided for presentation and release to the Restoration Advisory Board for the Badger Army Ammunition Plant and the general public by the US Army Environmental Command.
