Sodium absorption ratio and the ion oalance <br />were calculated. <br />The results of these analyses are presented in the following tables and <br />are reported irc mg/1 unless other+ise indicated. <br />Table No. 1 <br />Concentration in mg/1 <br />Allen Mine - 1/16/80 <br />Parameter Above Discharge Below <br />Boron <0.010 <0.010 <0.010 <br />Calcium 52 10 53 <br />Iron, total 0.22 0.13 0.21 <br />Magnesium 10 2.9 11 <br />hanganese, total 0.03 <0.01 0.03 <br />~d ~"F~ .: <br />.~_' <br />., <br />az~"- <br />
