21 <br />for this site was 1.7 mg/l. The Table 3 standard for <br />agricultural use is .2mg/l. The maximum level ever <br />recorded for this site according to Table 21A is 4.31 <br />mg/l and the average is 1.3mg/l. <br />• Conductivity is elevated at this downstream well. No <br />projected level is set for this site in the PHC. During <br />July and September; Conductivity at surface water <br />Site 8 for Foidel Creek was reported above the <br />maximum reported conductivity at Site 800 and 14. <br />TDS(Lab) levels during August and September were <br />higher than the maximum levels reported for Site 8 <br />and 14. TC indicated the increase in Conductivity is <br />likely a result of increased discharge from Pond D as <br />a result of overflows with the Area 1 Pond which a <br />partially fed by mine water. <br />Fish Creek Alluvium <br />The PHC indicates that mine discharge water will impact <br />Fish Creek and its alluvium. <br />-Well 008 -AU -3 <br />• Average conductivity at this site is reported to be <br />1057.5 UMS/cm which is greater than the maximum <br />projected amount for the Fish Creek Alluvium in the <br />PHC. However, it is below the material damage <br />level of 1,500 umhos/cm set in the PHC. <br />Trout Creek Alluvium <br />The conductivity levels were projected in the PHC. <br />-Well 008 -AT -1 <br />• Conductivity was reported to be 766, 693 and 665 on <br />July 23, August 18 and September 2, 2014. This is <br />near the projected level estimated in the PHC on <br />page 2.05-146 and below the 1,500 material damage <br />level set for this site. <br />• The water levels for the well are elevated above the <br />levels previously recorded. TDS is below the levels <br />recorded. <br />21 <br />
