  <dc:description>&lt;p&gt;&lt;span class="EXLDetailsDisplayVal"&gt;Data are presented on more than 300 &lt;span class="searchword"&gt;wells&lt;/span&gt;, including many new ones whose &lt;span class="searchword"&gt;records&lt;/span&gt; will not be a part of a forthcoming interpretative report on the occurrence of &lt;span class="searchword"&gt;ground&lt;/span&gt; &lt;span class="searchword"&gt;water&lt;/span&gt; in this &lt;span class="searchword"&gt;area&lt;/span&gt;. 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 &lt;span class="searchword"&gt;records&lt;/span&gt; there are 124 driller's logs and a table of &lt;span class="searchword"&gt;chemical&lt;/span&gt; analyses of the &lt;span class="searchword"&gt;ground&lt;/span&gt; &lt;span class="searchword"&gt;water&lt;/span&gt;.&lt;/span&gt;&lt;/p&gt;</dc:description>
