The <br /> samples were given our identification IAD 7497-EO01-032-12. <br /> The samples were analyzed for calcium, iron, magnesium, manoanese, 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 /> The results of these analyses are presented in Table Plo. 1 and are reported <br /> in mg/l unless otherwise indicated. <br /> I J„ <br /> • L - <br />
