Fall 2023 - In The Flow - USGS Maryland-Delaware-Washington DC Water Science Newsletter
The USGS MD-DE-DC Newsletter focuses on water science issues in our region.
The fourth edition of "In The Flow," the newsletter of the Maryland, Delaware, Washington, D.C. Water Science Center focused on water science issues and solutions in our region.
Tracking Our Rivers and Streams: How USGS Surface Water Monitoring Provides Important Information For The MD-DE-DC Region
As humans leave an ever-increasing impact upon the earth’s natural resources, and in an increasingly complex world of water infrastructure and man-made structures, understanding where water comes from and where it flows to is more important than ever. One of the U.S. Geological Survey’s core capabilities is to monitor our nation’s waterways, providing publicly available data that impact all our lives.
The USGS has 190 surface water streamgages in Maryland, Delaware, and Washington, D.C., which are part of the USGS’ network of over 11,000 automated streamgages collecting continuous data on streams, rivers, lakes, canals, rainfall, and more.
Our publicly available high-quality USGS data is used by federal partners, states, municipalities, non-profits, meteorologists, and citizens, so it’s important that we report accurate data. That’s why you can find our dedicated crew of hydrologic technicians collecting measurements and servicing our gages on nearly any day of the year, rain or shine, holidays and weekends.

Leetown PFAS Lab Studies An Emerging Contaminant of Concern
PFAS, also called “forever chemicals,” are emerging contaminants of concern that can be found in air, rain, lakes, rivers, groundwater, soils, and in products we use every day, like non-stick pans and popcorn bags. PFAS exposure has been associated with a variety of human and ecosystem health effects, making it very important to have good analytical methods to ensure the data is of the highest quality.
The U.S. Geological Survey laboratory for the analysis of per- and polyfluoroalkyl substances (PFAS) uses cutting-edge techniques to analyze environmental samples including tissues, plasma, water, and soils to undertake and support research projects across the country.

Every year, the USGS Maryland-Delaware-District of Columbia Water Science Center awards employees and teams for their outstanding contributions to our center. Their selfless dedication, scientific excellence, and work ethic bring great credit upon themselves and the U.S. Geological Survey, and truly uphold the USGS motto, "Science for a changing world."
Updates To Our Gage Network
Please welcome our latest water quality gages located at Northwest Branch Anacostia at Brentwood, MD (01651003) and at Monocacy River near Dickerson, MD (01643580). Both streamgages collect data on gage height, specific conductance, temperature, and turbidity. The Anacostia gage also provides discharge measurements, and the Monocacy gage also collects data on dissolved oxygen, pH, and stream water-level elevation.
In other water-quality news, we added a nitrate sensor to our gage at the Choptank River near Greensboro, MD (01491000), which collects continuous nitrate plus nitrite data. The additional sensor augments our existing water-quality capabilities at this site.
Testing New Water Quality Observation Methods In Philadelphia
When USGS scientists need to test new ways of monitoring waterways, we use a test bed! This site is located at Penn's Landing in Philadelphia, Pennsylvania, a crucial point of the Delaware River, and is operated by the Pennsylvania Water Science Center.
The Delaware River is rich in history, ecologically diverse, and critical to the regional economy. Water managers in this basin have a long history of applying innovative solutions to ensure the long-term sustainability of a treasured resource that provides drinking water to over 15 million people in the region.
Implementing the USGS Next Generation Water Observing System (NGWOS) in the Delaware River Basin provides an opportunity to develop an integrated system to support innovative modern water prediction and decision support systems in a nationally important, complex interstate river system.
