Microbial Contamination of Water Resources in the
Chattahoochee National Recreation Area, Georgia

DATA TABLES

Data were collected from March 22, 1999 to April 2, 2000. The links on this page allow you to view data tables or download data in tab-delimited files. Organic wastewater tracer data are not available online. (1) Fixed-interval sites: Fecal-indicator bacteria (fecal coliform, E. coli, and enterococci), turbidity, and field paramters (stage, specific conductance, water and air temperature, pH, dissolved oxygen, and percent saturation) measured every five days during the summer recreation season (April 1- September 30) and every 8 days from October 1, 1999 to March 30, 2000 at three main stem Chattahoochee River sites. The Chattahoochee River National Recreation Area sampling sites: Chattahoochee River near Suwanee (Settles Bridge Road): March 26, 1999 to April 2, 2000 Chattahoochee River near Atlanta (Johnsons Ferry Road): March 26, 1999 to April 2, 2000 Chattahoochee River at Atlanta (20 feet upstream from Paces Ferry Bridge): March 22, 1999 to April 2, 2000 (2) Synoptic surveys: - Fecal-indicator bacteria (including Clostridium perfringens), F-specific and somatic coliphages, turbidity, field parameters, and organic wastewater tracers were measured during different hydrologic conditions at four main stem Chattahoochee River sites and 8 sites on streams tributary to the Chattahoochee River. Synoptic #1: June 15, 1999 (widespread thunderstorms previous evening and afternoon; most samples were collected when streams were receeding) Synoptic #2: September 8, 1999 (dry summer; base-flow conditions) Synoptic #3: February 22, 2000 plus supplementary sampling on March 1, 2000 (dry winter; base-flow conditions) Synoptic #4: April 2, 2000 (wet spring; storm-flow conditions) (3) Diel samples: - Fecal-indicator bacteria, turbidity, field parameters, and nutrients measured every 2 hours for a 26-hour period at the Chattahoochee River at Atlanta. Nutrient data are available in downloadable files. Diel: August 4-5, 1999, (summer, base-flow conditions) Download all project data in tab-delimited files for use in spreadsheet programs.
