<br />~~~\.~ <br /> <br />was completed August 9, 1968. Four hundred sixty sacks of cement 'Jere <br /> <br />used to plug the well. <br />. <br /> <br />The total contract cost was $35,52l.45 for plugging the two wells <br /> <br />including $27,443.95 for the Meeker 'Jell on White River and $8,077.50 for <br /> <br />the Piceance Creek well. Total cost including engineering is estimated to <br /> <br />be about $40,000. <br /> <br />REEULTS ON fALINITY <br /> <br />Meeker Well <br /> <br />The Bureau of Reclamation periodically obtains quality samples at the <br /> <br />Geological Survey gage, White River below Meeker. Table 3 shows the anal- <br /> <br /> <br />ysis of l7 samples obtained during the 2 years preceding and 4 samples ob- <br /> <br />tained follo'Jing the plugging of the well. <br /> <br />The analysis of the samples <br /> <br />obtained after the well was plugged indicates that the concentration and <br /> <br />load of sodium has been reduced over 50 percent, chloride over 75 percent, <br /> <br />and sulfate just slightly. The quantity of potassium is too small to de- <br /> <br />termine any improvement from this table. Figure 1 shows the decrease in <br /> <br />the sodium and chloride concentration ai'ter plugging the well. Table 4 <br /> <br />sho'Js the mineral concentration of samples obtained s;nce Jw,c 1964 ad- <br /> <br />justed to the concentration of the August 1, 1968, sample.
