Well Predicted TDS values (mq /1) <br />YOV30 <br />3201 <br />YW30 <br />2570 <br />YWC33 <br />2721 <br />YAAL14 <br />2036 <br />YGAL16 <br />1296 <br />YSALl <br />798 <br />YSAL3 <br />798 <br />* indicates <br />value above prediction <br />This years average TDS (mq /1) <br />2180 <br />5680* <br />780 <br />3630* <br />1570* <br />1710* <br />1240* <br />At Annand Draw alluvial well YAAL14, the TDS value observed this year <br />was 3630 mg /1. This value exceeds the predicted value of 2036 mg /l. The <br />GWPOC well for the Grassy Creek Alluvium (downstream of Annand Draw), <br />SGAL70, did not exceed the TDS GWPOC standard, 5038 mg /1'. <br />At Grassy Creek alluvial well YGAL16, the TDS value observed this year <br />was 1570 mg /l. This value exceeds the predicted value of 1296 mg /l. The <br />GWPOC well for the Grassy Creek Alluvium, SGAL70, did not exceed the TDS <br />GWPOC standard, 5038 mg /l. <br />At Sage Creek alluvial well YSAL1, the TDS value observed this year was <br />1710 mg /l. The TDS value observed this year upstream at Well YSAL3 <br />(directly below Pond 012) was 1240 mg /l. These two values exceed the <br />predicted value of 798 mg /1. The GWPOC well for the Sage Creek Alluvium, <br />YSAL3, did not exceed the TDS GWPOC standard, 2675 mg /l. TDS values at <br />YSALl are displaying a decreasing trend. <br />This years TDS value at Wadge coal well YW30 was 5680 mg /l. The PHC <br />predicted value for this well is 2570 mg /1. TDS values have been on the <br />rise at this well from 2008 to 2011. However, in 2012, the TDS value was <br />less than the 2011 value (7270 mg /1), possibly indicating a downward <br />trend. More data from this well will be needed to determine if the <br />recent trend is an anomaly. <br />Surface Water <br />I <br />
