Water Resources of Maryland, Delaware, and the District of Columbia
Welcome to the U.S. Geological Survey (USGS) web page for the water resources of Maryland, Delaware, and the District of Columbia. Here you will find links to USGS data, projects, and publications about water resources, including streams and rivers, groundwater, water quality, and water use.
The USGS operates the most extensive satellite network of stream-gaging stations in the region. The data provided by this network are used for monitoring water conditions in a timely manner, such as during floods.
Current Spotlight
The Fate and Bioremediation Team
The USGS MD-DE-DC Water Science Center is organized into work teams. The work team brings together projects that investigate similar water resource issues to encourage sharing of individual expertise, data collection methods, and personnel. The goal of 2012 is to have every work team in the Center develop their own website to describe the type of work that the team does and the science behind their particular field. The Fate and Bioremediation Team is the first team to complete their website.
