USGS hydrologists use boats to access sites for water sampling.
Cristal Younker of the SAWSC drives a boat to site 02226160, Altamaha River at Everett City, Georgia, to collect samples for the National Water Quality Program (NWQP) trends sampling. The NWQP provides an understanding of water-quality conditions; whether conditions are getting better or worse over time; and how natural features and human activities affect those conditions

DNA analysis of water samples can indicate sources of pollution.
Anna McKee of the SAWSC, Norcross, GA, prepares DNA from water samples to test for bacteria that indicate sources of fecal contamination. Understanding the sources of contamination can help target mitigation and outreach efforts.
Studying water quality involves lab work to prepare and analyze water.
Kelsey Simmons and Kaamilya Najeeullah of the SAWSC prepare a sample from site 02336240 S.F Peachtree Creek Johnson Rd, near Atlanta, GA. The sample is part of routine water-quality monitoring for water-shed protection in Dekalb County, GA.

USGS Scientists Get Ready for Hurricanes
A USGS hydrologic scientist installs a storm-tide sensor near the North Carolina coast as Hurricane Florence approaches.
USGS Storm-Tide Sensor for Hurricane Florence
A USGS storm-tide sensor, deployed in advance of Hurricane Florence's landfall. The sensors are housed in vented steel pipes a few inches wide and about a foot long. They are being installed on bridges, piers, and other structures that have a good chance of surviving the storm.
The information the sensors collect will help define the depth and duration of a storm
