~. <br />CONCLIISION <br />The results of this test suggests that the acute toxicity exhibited <br />by Somerset Mining effluent is due to the high alkalinity. It <br />should be noted however, that there are no current maximum <br />alkalinity limits on Somerset effluent. It is also pointed out <br />that the alkalinity in Somerset discharge may have little effect on <br />the Gunnison River organisms due to river dilution. The current <br />IWC for Somerset Mining Company is 1%. <br />-6- <br />COMMERCIAL TESTING & ENGINEERING CO. <br />mnal Copy Watermarketl <br />°or Your Protection <br />
