From abstract: This data release presents preliminary results of ground water, stream sediment, and stream water reconnaissance in the National Topographic Map Series (NTMS) Portland 10 x 20 quadrangle. Stream sediment and stream water samples were collected from small streams at 1094 sites for a nominal density of one site per 13 square kilometers (five square miles) in rural areas. Ground water samples were collected at 560 sites for a nominal density of one site per 26 square kilometers (ten square miles). Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium …

Description
From abstract: This data release presents preliminary results of ground water, stream sediment, and stream water reconnaissance in the National Topographic Map Series (NTMS) Portland 10 x 20 quadrangle. Stream sediment and stream water samples were collected from small streams at 1094 sites for a nominal density of one site per 13 square kilometers (five square miles) in rural areas. Ground water samples were collected at 560 sites for a nominal density of one site per 26 square kilometers (ten square miles). Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 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.
