Ratio of the Sum of Reacting Constituents to Specific Conductance <br /> The ratio of the sum of reacting cations (meq/L) to 0.01 times specific <br /> conductance, as well as the sum of reacting anions (meq/L) to 0.01 times specific <br /> conductance, should be within the range 0.92 to 1.241. This ratio is calculated as <br /> follows: <br /> Sum of reacting cations (or anions) in meq/L <br /> 0.01 x Specific Conductance <br /> Five of the nine samples for cations (56 percent) and two of the nine samples for <br /> anions (22 percent) did not fall within the recommended range. The results are <br /> summarized in the following table. <br /> Specific Ratio of Ratio of Anions <br /> Site Date Conductance Cations to to 0.01 Specific <br /> (US/CM) 0.01 Specific Conductance <br /> Conductance <br /> KMW-1 5/3/2010 3,673 1.16 1.13 <br /> KMW-2 5/3/2010 2,839 1.25 1.20 <br /> KMW-3 5/3/2010 4,368 1.26 1.29 <br /> KMW-4 5/3/2010 3,239 1.29 1.28 <br /> KMW-6 5/3/2010 1,218 0.83 0.96 <br /> KMW-7 5/3/2010 3,521 1.17 1.08 <br /> W-1 5/3/2010 3,265 1.27 1.21 <br /> W-2 5/3/2010 2,011 1.14 1.06 <br /> MW-5 5/3/2010 4,218 1.20 1.14 <br /> Percent differences in bold are outside the recommended limit. <br /> - E-5 - <br />
