M26144 <br />~I Corrected Analytical Report <br />Water samples were received for analyses on 20, 1979. The <br />samples were given our identification fA0 X97-C543-032-07. <br />1 <br />This report is to report values for Doron after re-analyzing the -, <br />y samples. <br />~l The samples were prepared for analyses by filtering through 0.45u <br />pore membrane filters. Barium, calcium, iron, magnesium, manganese <br />I' and silicon were determined'by flame atomic absorption, potassium <br />and sodium by flame atomic emission spectrophotometry, and arsenic <br />and selenium by hydride generation. <br />T•he remaining parameters were determined by the methods of U.S. <br />Geological Survey Techniques of Water Resources Investigation, <br />Chapter A1, Book 5. <br />the results of these analyses are presented in the following tables <br />and are reported in mg/1 unless otherwise indicated. <br />i <br />~ if you have any questions concerning these analyses, please call. <br />I` <br />F cKT~~L•t ~~n ..J <br />Ernest App ans, Ana yst <br />EA/as <br />ti~• \ ~\ <br />M, L.
