Alkalinity, chloride, <br /> fluoride, hardness, pH, sulfate, specific conductance, suspended <br /> solids, oil & grease, and dissolved solids were determined by the <br /> �• procedures of Standard Methods, 14th edition. Ion balance and <br /> sodium absorption ratio were calculated. <br /> The results of these analyses are presented in the following tables <br /> and are reported in mg/l unless otherwise noted. <br /> The Allen Mine 4/22/80, 11:50 sample has an ion balance problem <br /> due to a lack of anions. Further work may be needed to make the <br /> ions balance. <br /> ,,o <br />
