Stephen S. Aichele
2004, Fact Sheet 2004-3120
In 1996, the U.S. Geological Survey (USGS), in cooperation with the Michigan Department of Environmental Quality (MDEQ) and nine southeast Michigan counties, began a study of the factors controlling arsenic concentrations in drinking water. The early results of this study raised broader concerns in Oakland County about the quality of...
An autonomous, electromagnetic seepage meter to study coastal groundwater/surface-water exchange
Peter W. Swarzenski, Matt Charette, Christian D. Langevin
2004, Open-File Report 2004-1369
The bi-directional exchange of groundwater with coastal surface waters may influence not only coastal-water and geochemical budgets, but may also impact and direct coastal ecosystem change. For example, the widespread discharge of nutrient-enriched submarine groundwater into an estuary or lagoon may contribute directly to the onset and duration of eutrophication,...
