Detailed Description
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 (https://www.usgs.gov/water-resources/national-water-quality-program).
