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.

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 thos

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.
