the river; well water with specific conductance indicative of dissolved - solids
<br />concentrations within the recommended limit occurs as far west as the area from
<br />Piceance Creek to Taylor Draw. In the western part of the study area, large
<br />sodium - adsorption ratios and large dissolved - solids concentrations in the
<br />ground water combine to make the water unfit for irrigation purposes.
<br />The results of this investigation are preliminary and are based mostly on
<br />data from existing wells and test holes. The variability in depth to bedrock
<br />and hydraulic properties of the aquifer need to be more accurately evaluated,
<br />especially southeast of Meeker and in the western part of Powell Park.
