<br />,..... <br />w <br />en <br />o <br /> <br />9 <br /> <br />Schneider (1975) also investigated the role of ground water <br /> <br />with. respect to salinity. He noted that ground water within the <br /> <br />Mancos Shale is too meager to be considered to be a significant <br /> <br />aquifer. However, ground water samples indicated that salts leached <br /> <br /> <br />from Mancos Shale contribute to ground water salinity, which is in <br /> <br />fact. saturated with respect to calcite and gypsum. He also observed <br /> <br />that., although the shale is vertically impermeable, ground water <br /> <br />recharge can occur along laterally interconnected planes and joints. <br /> <br />Schneider concluded that the unlined Government Highline Canal is a <br /> <br />major contributor to ground water salinity in the Grand Valley. <br />
