SAMPLING AND MONITORING <br /> 4.1 Sampling and Analytical Plan <br /> The sampling and analytical plan is found below in Tables 13 and 14 for the bench- and <br /> pilot-scale testing, respectively. While not included in the Work Plan, OSMI may <br /> decide to include WET testing as part of the pilot-scale testing. Additionally, speciation <br /> of metals that are not successfully reduced through the treatment system should be <br /> conducted to help understand why and identify an approach to address the challenge. <br /> Table 13: Bench-Scale Jar Testing Sampling and Analytical Plan for One Jar <br /> Testing Event <br /> Number of Samples <br /> Constituent Method for the One Proposed <br /> Jar Test* <br /> Turbidity Turbidimeter 13 <br /> pH pH Probe 13 <br /> Temperature Thermometer 13 <br /> Conductivity Conductivity Probe 13 <br /> Total Metals Analysis M200.7 ICP 13 <br /> Dissolved Metals Analysis M200.8 ICP-MS 13 <br /> TDS &TSS 13 <br /> *Number of samples includes 1 sample of the input water,and 2 jar tests of 6 jars each for the output <br /> water;the Work Plan assumes two jar testing events(low flow water and high flow water),so the total <br /> number bench-scale samples will double at the completion of all jar tests and there will be additional QC <br /> samples(10%)to ACZ <br /> Treatabiliry Study Work Plan 22 February 8,2018 <br />
