Other test sites showed little or no change in water quality.</p><p>Report author Melanie Clark says the changes occur because water that&rsquo;s extracted during gas production sometimes flows into the streams and rivers.</p> Sat, 28 Jul 2012 00:36:54 +0000 Willow Belden 27627 at http://wyomingpublicmedia.org USGS study shows gas production can affect stream water
