  <dc:description>&lt;p&gt;The Midwestern Basins and Arches Regional Aquifer-Systems Analysis (RASA) is one of 28 projects that were identified by Congress in 1978, after a period of severe drought, to be studied by the U.S. Geological Survey (Sun, 1984). &amp;nbsp;The Midwestern Basins and Arches RASA study area in parts of Indiana, Ohio, Michigan, and Illinois is defined by either the limestone-shale contact of rocks of Devonian age or by the contact of the land with surface-water bodies (fig. 1).&lt;br&gt;&lt;/p&gt;</dc:description>
