Sodium absorption ratio and the ion balance <br />were calculated. <br />The results of these analyses are presented in the following tables and <br />are reported in mg/1 unless othernaise indicated. <br />Table No. l <br />Concentration in mg/l <br />Parameter <br />Boron <br />1 Calcium <br />Iron, total <br />• Magnesium <br />t Manganese, total <br />Allen Mine - 1/16/80 <br />Above Discharge Below <br /><0.010 40.010 <0.010 <br />52 10 53 <br />0.22 0.13 0.21. <br />10 2.9 11 r' <br />S <br />0.03 40.01 0.03 <br />.,t LINO I. rr I. , rare -w. a .
