The <br />• samples were given our identification IAD =97-E001-032-12. <br />The samples were analyzed for calcium, iron, magnesium, manganese, and zinc <br />by flame atomic absorption, for sodium and potassium by flame atomic emission, <br />and for selenium by hydride generation atomic absorption. <br />Boron was determined colorimetrically. Alkalinity, cnloride, fluoride, hard- <br />ness, pH, sulfate, specific conductance, suspended solids, oil and grease, <br />and dissolved solids were determined by the procedures of Standard Methods; <br />14th edition. Ion balance and sodium absorption ratio were calculated. <br />7 <br />The results of these analyses are presented in Table No. 1 and are reported <br />in mg/l unless otherwise indicated. <br />�I <br />:(L <br />�a.�.•,.ca.r.n....c-......c..nuro..•............r. ...c: .n..0 o-. c,..n <. cr. c.. ir. .... ... .v... .Oc. 1,nm .. <br />
