The sample <br />was given our identification fAb x'97-6456-280-01. <br />A large portion of the sample was filtered thrcugh a 0.45 micron ~nein~rane <br />filter. The filtrate was analyzed fur aluminulll, barium, beryllium, calciun, <br />admium, chromium, cooper, iron, lead, magnesium, monganese, molybdenum, <br />~ckel, silver, sodium, thallium, and zinc by flame atomic absorption; <br />sonic and seleniwn by hydride generation; mercury by cold vapor flameless <br />atomic absorption; uranium was determined fluorometrically. <br />Boron was determined colorimetrically by cur•cumin reagent. Ammonia nitrogen <br />and iota] phosphorous ~yere determined by the procedures of EPA Storet =005:u <br />and ~OOG65, respectively. Chloride, fluoride, and pH were determi•~ed by specific <br />ion electrode methods. The remaining parameters erer•e determined by the procedures <br />of Standard Methods, 14t1i edition. <br />A portion of the filtered sample was extracted with chloroform and then <br />with toluene, at neutral pll, following the guidelines of ASTht D217~1-70 to <br />obtain an indication of leached organic compounds. .The determination teas <br />done by gas chromatography. . <br />The results of these analyses are presented in Table llo. 1 - Metallic <br />Constituents, Table No. 2 - Non-Metallic Constituents, and Table No. 3 - <br />Organic Constituents. <br />Table 1Jo. 1 - Metallic Constituents <br />Concentration in mg/1 <br />Parameter Water Sample <br />A]uminum 4.28 <br />.
