<br /> <br />In general, the water was all very hard `with a•/erage TDS values ranging from <br />~5d mg/1 to 2,150 mgit. Sul Fate was generail mcre dcminant than <br />bicarbonate. One spring, 5-25, had an av?rage TDS value of 25,557 mg/1, wnich <br />is anemaiou;iy hign. The applicant ha; postulated that this may be due to: <br />1) the spring being located a` the tee of a landslide (high TDS values <br />may be a result of morn be7rJC 2rpOSUYe tJ bny5lCd~ dnd CnemlC3' <br />weathering processes as water passes through the slide); <br />2) the flow being '/ery icw (less than 0.5 g/m); evaporation at the <br />spring wCUi7 tend tJ hignly concentrate :alt; to the water; <br />3> the sbring md'/ be t~ntaminat?; by the salt biOC~S which are 1GCa`.?: <br />in the dYei fJr 1i•reSbJC:< U52. <br />All but two springs experienced a decline in flow during the course of the <br />summer. Five had dried up by late August, three others flowed less water <br />during bass flow and two were flowing at about the same rate in Oc*.ober as in <br />June. <br />Four springs, Olson Spring, S-5, S-.5, and 5-41, are expected tJ be impacted <br />by mining, one Of 'which, ~-41, feedi 3 reg'stered StJCZ pond, 'wn112 DiiJn <br />Springs 1$ do ddjUdiCdt2d dcmesti;: w3Ler right.
