KLEINFELDER <br /> Upper Tolerance Limit(UTL): <br /> UTL=(Mean of Data Set)+[(Normal Tolerance Factor)x(Standard Deviation of Data Set)] <br /> Using this formula the Upper Tolerance Limit for each of the Constituents of Concern <br /> was calculated using the historic groundwater quality in MW-5 (background water <br /> quality). Those UTLs are as follows. <br /> Constituent of Mean of Standard Normal Units Upper <br /> Concern Data Set Deviation Tolerance Tolerance <br /> Factor Limit <br /> UTL <br /> Total Dissolved 704.5 372.19 2.523 mg/l 1,644 <br /> Solids <br /> Bicarbonate 385.12 239.13 2.523 In 988 <br /> Chloride 82.93 61.14 2.614 m 289 <br /> Nitrate as N 52.13 109.28 2.566 mg/1 330 <br /> Sulfate 32.41 46.31 2.614 m 153 <br /> Specific 1,124 600 2.523 umhos/cm 2,638 <br /> Conductance <br /> Calcium 134.18 113.20 2.523 mg/1 420 <br /> Sodium 71.52 30.00 2.614 mg/1 150 <br /> 6.2 EXCEEDANCE PROTOCOL <br /> In the event that the analytical result of any groundwater monitoring event for a Point of <br /> Compliance exceeds the Concentration Limit(Upper Tolerance Limit), a resampling of that point <br /> would occur. In the event that the exceedance is confirmed, RWQCB staff will be notified that a <br /> statistically significant detection has occurred. <br /> 20-3978-03.MTG/2002R046r/2002L082 Page 10 of 11 <br /> Copyright 2002,Kleinfelder.Inc.
