• Surface rater quality data measured at all stream, spring, and NPDBS sites during 1995 <br />rare compared with the standards list for livestock drinking rater (Table 6, see Ground <br />Water section) . No exceedenees of any of these standards sere noted at any of these <br />sites. <br />Whole effluent toxicity (WST) tests on samples collected on Nay 16 and Nay 22 from NFDEB <br />005 failed effluent criteria. WET aa¢Qales collected on June 1 and June 6 both passed, <br />thereby closing the incident. Nay 23, ,lone 28, and July 27 letters to the Colorado <br />Department of health are provided rith their associated DNR in Appendix P. It should be <br />noted that during the txo WET test failures, discharges from 005 were 3.5 and 0.6 gpm, <br />respectively. Flora at its receiving stream, 9ubberaon OUlch, rem greater than 2000 qpm <br />during the sane time frame. As a insult, no harm to Huhberson Gulch vas likely done. <br />Surface Water Summary. The limited amount of mining that has occurred at this mine <br />(mining began in 1990) has had little effect on surface rater qualrty.
