2 <br />operational statistics are calculated for all data prior to the reporting period. <br />Numeric protective levels (NPL) and early warning indicators (EWI) are shown for <br />each constituent at each well where these statistical values apply. Comparison <br />of the data values with the Early Warning Indicators (EWI) and the Numeric <br />Protective Levels (NPL) indicates two dissolved boron values above the <br />calculated limits during the sample period. <br />Analysis of the data collected in the 30t" Quarter shows one data point for <br />dissolved boron slightly elevated above the NPL indicator at Uinta well 21-3U. <br />The sample, collected in March 2008, indicates a value for dissolved boron of 3.7 <br />mg/L. The calculated NPL for this constituent at this monitoring point is 3.64 <br />mg/L, a difference of 0.06 mg/L. The baseline mean value for dissolved boron is <br />3.25 mg/L computed from 15 baseline samples. The operational mean value <br />determined from 65 total samples is 2.90 mg/L. The maximum value observed in <br />the baseline program was 7 mg/L. The value of dissolved boron at alluvial well <br />21-3U has exceeded the NPL indicator twice before during the period of record <br />(2/15/00 baseline value of 7 mg/L and 12/5/06 value of 4.1 mg/L). <br />Well 21-3U <br />Water Elevation and Boron Concentration <br />8 <br />I 7 <br />J 6 <br />5 <br />4 <br />3 <br />6 2 <br />1 <br />Numeric Protective Level = 3.64 mg/L <br />Operational <br />0 •------ -------- --- - - <br />~ ~ $ g ~ g ~ ~ ~ ~ ~ ~ <br />r. ~ r~ c~1 n ~ c'1 ~ ~ cif n <br /> Date <br />,_- Water ~evation ~--cam--Boron, dissolved <br />~ ~ ~ <br />6095' <br />6094 <br />6093 <br />6092 <br />6091 <br />~ ~' 6090 <br />ti m 6089 <br />60881 <br />Temporary 6087 <br />Suspension anaa <br />----r--- 6085 <br />~ ~ <br />Boron Numeric Protective Level <br />
