Hydrologic study at Farm Creek Marsh, Dorchester County, Maryland, from April 2015 to April 2016
In 2015, the U.S. Geological Survey began a 1-year hydrologic study to investigate the extent and cause of inundation at Farm Creek Marsh, in Dorchester County, Maryland. In combination with a tide and precipitation gage, a representative section of the marsh was instrumented with surface-water monitors and shallow groundwater piezometers to capture the spatial and temporal extent of inundation.

Anacostia Water Quality Monitoring Project
The broad goal of the study is to significantly expand data collection at the Northeast Branch Anacostia and Northwest Branch Anacostia to include water-quality sampling and analysis for a wide suite of natural and anthropogenic constituents (nutrients, sediment, metals, bacteria, and organics such as PCBs and PAHs). MD-DE-DC WSC Project #LF00BK4MD-DE-DC WSC Contaminant Fate and Transport Capabilities
The Contaminant Fate and Transport team conducts research on the transport and fate of contaminants in groundwater through the unsaturated and saturated zones using innovative and proven USGS methods. The team's research focuses on the often complex processes that affect contaminant fate and transport, and includes expertise in wetland environments. Performing both field and laboratory studies to...MD-DE-DC WSC Modeling Capabilities
USGS models are widely used to predict responses of hydrologic systems to changing stresses, such as increases in precipitation or ground-water pumping rates, as well as to predict the fate and movement of solutes and contaminants in water.The USGS is at the forefront of devising new techniques and computer software to solve practical problems in the study of water resources. Predictive models are...MD-DE-DC WSC Laboratory Capabilities
The labs at the MD-DE-DC WSC are clean, well-stocked, and appointed with modern equipment and a highly talented staff. The three labs analyze samples, conduct controlled-environment chemical tests with GCMS in the Water Qualty lab. Scientists and technicians work with core samples and analyze soils in the Sediment Lab. Our labs assure reliability, reproducibility, and high quality of its data and...MD-DE-DC WSC Seminar Series

MD-DE-DC WSC Water Quality Capabilities
Water quality is a measure of the suitability of water for a particular use based on selected physical, chemical, and biological characteristics. Water-quality monitoring is used to help water-resource managers understand and avert potential negative effects of man-made and natural stresses on water resources, evaluate trends, and compare to water-quality criteria. One of our primary functions at... - News
