[en] Results of ground water and stream sediment reconnaissance in the National Topographic Map Series (NTMS) Atlanta 1⁰ x 2⁰ quadrangle are presented. Stream sediment samples were collected from small streams at 1312 sites or at a nominal density of one site per 13 square kilometers in rural areas. Ground water samples were collected at 951 sites or at a nominal density of one site per 18 square kilometers. Neutron activation analysis results are given for uranium and 16 other elements in sediments, and for uranium and 8 other elements in ground water and surface water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps. Statistical summaries of data and a brief description of results are given. A generalized geologic map and a summary of the geology of the area are included
