Sodium aosorption ratio and the ion oalance <br />were calculated. <br />The results of these analyses are presented in the following tables and <br />are reported in mg/1 unless otherwise indicated. <br /> Table 10. 1 <br /> Concentration in mg/1 <br /> Allen Mine - 1/16/80 <br />Parameter Above Discharge De low <br />Boron <0.010 <0.010 -0.010 <br />Calcium 52 10 53 <br />• Iran, total 0.22 0.13 0.21 <br />Magnesium 10 2.9 11 <br />i Manganese, total 0.03 <0.01 0.03 <br />~- <br />~`C., <br />:~._ <br />
