In summary, the water quality of the upper and lower coal aquifers is <br />not suitable for irrigation. The coal water could be utilized for <br />livestock drinking water if lead concentrations were reduced. <br />The coal aquifers water quality are characterized as presented below: <br />• LC-1, LC-4 Na-Ca carbonate waters low in nutrients <br />and trace elements. Fe and Al are present <br />in noticeable quantities. <br />• UC-I, UC-2 Na-Ca carbonate waters low in nutrients and <br />trace elements Fe and Al are presented in <br />noticeable quantities with generally high <br />concentrations of TDS. <br />• LC-3 CA - chloride water with significantly high <br />sulfate content. <br />• SP-3, SP-5 Ca - bicarbonate low in iron and TDS concentrations, <br />best quality water on site with extremely low sodium <br />content. <br />4.2.4 Hydraulic Properties of the Aquifers <br />In order to define the hydraulic properties of the specific isolated <br />aquifers, three pump tests were conducted. The wells were blown out <br />after construction and allowed to stabilize prior to pump testing. <br />The aquifer tests were conducted on well LC 2 and LC 4 in the lower <br />coal zone and on well UC 2 in the upper coal zone. The tests were <br />conducted by inserting one. inch flexible plastic pipe into the wells <br />and injecting air from a compressor to obtin a constant flow of water. <br />The flow rate was monitored as it passed through a cutthroat flume. <br />These data are presented in Tables 10 through 12. <br /> <br />39 <br />''J ~ ~ . .. _ ._:..:a~s nis.+r~u.:r <br />
