  <dc:description>&lt;p&gt;&lt;span&gt;Watercourse aquifer systems in many areas are adversely affected by&amp;nbsp;&lt;/span&gt;wastes&lt;span&gt;&amp;nbsp;&lt;/span&gt;disposed&lt;span&gt;&amp;nbsp;into surface‐&lt;/span&gt;water&lt;span&gt;&amp;nbsp;sources, resulting in either reduced streambed permeability,&amp;nbsp;&lt;/span&gt;infiltration&lt;span&gt;&amp;nbsp;of&amp;nbsp;&lt;/span&gt;wastes&lt;span&gt;&amp;nbsp;into the aquifer, or both. These conditions are illustrated&amp;nbsp;&lt;/span&gt;at&lt;span&gt;&amp;nbsp;&lt;/span&gt;Lancaster&lt;span&gt;,&amp;nbsp;&lt;/span&gt;Ohio&lt;span&gt;, where low streambed permeability in the vicinity of the municipal well field, resulting from the discharge of&amp;nbsp;&lt;/span&gt;wastes&lt;span&gt;&amp;nbsp;to the&amp;nbsp;&lt;/span&gt;Hocking&lt;span&gt;&amp;nbsp;&lt;/span&gt;River&lt;span&gt;, seriously retards the&amp;nbsp;&lt;/span&gt;infiltration&lt;span&gt;&amp;nbsp;of surface&amp;nbsp;&lt;/span&gt;water&lt;span&gt;&amp;nbsp;and lessens the available yield of the wells. The&amp;nbsp;&lt;/span&gt;wastes&lt;span&gt;&amp;nbsp;consist of brine and iron‐laden effluent from the municipal treatment plant, discharged within the area of influence of the pumped wells to a stream already carrying much organic&amp;nbsp;&lt;/span&gt;waste&lt;span&gt;&amp;nbsp;and other debris. Upstream from the discharge sewer, muck and organic debris have accumulated thickly on the streambed, while downstream from the sewer the streambed sediments have become tightly cemented by iron and other constituents in the&amp;nbsp;&lt;/span&gt;waste&lt;span&gt;&amp;nbsp;&lt;/span&gt;water&lt;span&gt;. There is evidence that, despite reduced streambed permeability,&amp;nbsp;&lt;/span&gt;wastes&lt;span&gt;&amp;nbsp;have entered the aquifer and have materially contributed to declines in well efficiency and to recurring problems of well maintenance. Conditions such as those illustrated&amp;nbsp;&lt;/span&gt;at&lt;span&gt;&amp;nbsp;&lt;/span&gt;Lancaster&lt;span&gt;&amp;nbsp;occur also&amp;nbsp;&lt;/span&gt;at&lt;span&gt;&amp;nbsp;Dayton and are not uncommon elsewhere in&amp;nbsp;&lt;/span&gt;Ohio&lt;span&gt;. Indirect contamination of aquifers and adverse physical and chemical alteration of streambed sediments, resulting from surface‐&lt;/span&gt;water&lt;span&gt;&amp;nbsp;&lt;/span&gt;waste&lt;span&gt;&amp;nbsp;disposal, may in many places pose a threat to the&amp;nbsp;&lt;/span&gt;ground&lt;span&gt;‐&lt;/span&gt;water&lt;span&gt;&amp;nbsp;supply. This fact should not be overlooked in determining&amp;nbsp;&lt;/span&gt;water&lt;span&gt;‐&lt;/span&gt;quality&lt;span&gt;&amp;nbsp;standards to be established under the&amp;nbsp;&lt;/span&gt;Water&lt;span&gt;&amp;nbsp;&lt;/span&gt;Quality&lt;span&gt;&amp;nbsp;Act of 1965.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</dc:description>
