Records of wells and springs, water levels, and chemical quality of ground water in the East Portland area, Oregon
Data are presented on more than 300 wells , including many new ones whose records will not be a part of a forthcoming interpretative report on the occurrence of ground water in this area . A brief description of the geomorphic features is given, and the characteristics of the rock units are summarized in a table. Principal aquifers are beds of loose sand and gravel in the early Pliocene Troutdale Formation, late Pleistocene fluviolacustrine deposits, and Recent alluvium. Locally, Columbia River Basalt (Miocene) and the Boring Lava (late Pliocene to Pleistocene) yield substantial amounts of wate.. In addition to well records there are 124 driller's logs and a table of chemical analyses of the ground water .
