[f the ion balance ratio is high it may <br />be due to small amounts of dissolved heavy metals in the sample, not <br />accounted for. Furthermore, in sitmples of high pH, alkalinity, relation- <br />ship calculations may include amounts of hydroxide ion that, althounh <br />not called for in the analysis, needs to be considered when balancing <br />ions. <br />~` <br />Hardness calculations are based on the amounts of dissolved calcium <br />tad magnesium to the samples. Again, if hardness numbers are lav, <br />it xould be due to small amounts of dissolved heavy metals in ehle <br />samples that are not accounted for. Hardness calculations should not <br />be made including total metals since a digestion puts into solution <br />additional amounts of suspended solids. ..;}~//"~~~~+}~~{~~J~~t~~~' <br />The results of these analyses are presented in the following tables and are ~4,'~ <br />reported in mg/1 unless otherwise noted. <br />"~ae•e" <br />
