The dissolved Sodium and Potassium were analyzed by <br />flame emission. Total Selenium was analyzed by hydride generation atomic <br />absorption. Samples for total metals were first digested in nitric <br />and hydrochloric acids. <br />Boron was determined colorimetrically, Sulfate turbidimetricaily, Chloride <br />and Fluoride by specific ion electrode by the procedures of EPA Methods <br />for Chemical Anal sis of tdater and Waste, 1979. Dissolved solids TDS , <br />Suspended Solids (TSS and oil and grease were determined gravimetri- <br />cally by the procedures of Standard Methods, 14th edition. pH, Carbonate, <br />Bicarbonate, Alkalinity and Specific Conductance were all done by <br />Standard Method's Procedures. Hardness, Sodium Absorption Ratio, and [on <br />Balance were calculated. <br />The results of these analyses are presented in the foliowing tables and <br />are reported in milligrams per litre (mg/1) unless otherwise noted. <br />( <br />±,~,?„_ . <br />~:`,~' <br />-~ ;fi <br />.n,.wea .n . nrwe.ur .~ . eru.arna.. .+ . cwwwa, r . cuvq.he. or . e,.vu. eo . ewew. ee . nue.++en.... ~.w., .a ..nmuNO.e. .. <br />
