These <br />samples were given our identification IAD ;97-E385-032-03. The first of <br />these samp'es was taken on April 23, 1980 and is reported separately from <br />the second and third samples which were taken the following day. <br />• The samples were analyzed for iron, manganese, calcium, magnesium, sodium, <br />and potassium by flame atomic absorption, and for selenium by hydride <br />generation atomic absorption. <br />Boron was determined colorimetrically. Alkalinity, chloride, fluoride, <br />hardness, pH, sulfate, specific conductance, suspended solids, dissolved <br />solids, and oil & grease were determined by the procedures of Standard <br />I-lethods, 14th edition. Ion balance and sodium absorption ratio were <br />calculated. <br />The results of these analyses are presented in the following tables and <br />are reported in mg/l unless otherwise indicated. <br />1 <br />i <br />a <br />,n uses. rr.u.r.e..r.0 •ewnlaa... •cuu u�•e...v.uava u.o.e.•e,au.co. eaao,r.ea•a.a,•sa.. o.uv u..a• <br />v..cOvv u.vVIR. o.o <br />wua•a..0 .,rNaar, r. ,. ..aw oa u.a. u•+o..au v..rn uo,.co..•uvn.,. ay.a.u..,�,•m.wu.+e.n•muoo,o+. ac c.. <br />
