Field parameters will be collected at the WMP prior to water sample collection. Field <br /> parameters include pH, specific conductivity, and temperature. Field and water quality <br /> parameters to be analyzed are listed in Table 2. Appendix C provides the sampling <br /> analysis, method, containers, preservation and holding times for each parameter. <br /> 7.0 SAMPLE DOCUMENTATION, HANDLING, PACKAGING, <br /> AND CHAIN OF CUSTODY <br /> The standard operating procedures for sample documentation, handling, packaging, and <br /> chain of custody are presented in SOP #7. Sample custody procedures are to be followed <br /> to ensure that sample integrity is maintained during collection, transportation, and storage <br /> prior to analysis. A minimum number of individuals will handle the samples. The field <br /> sampler is personally responsible for collection and custody of the samples until they are <br /> transferred to the lab. <br /> 8.0 FIELD QUALITY ASSURANCE AND QUALITY CONTROL <br /> PROCEDURES <br /> 8.1 Field Parameter Instrument Calibration and Measurement <br /> Field parameter instruments and calibration/measurement procedures are presented in <br /> SOP #9. Ground water field parameters include pH, conductivity and temperature. <br /> Surface water field parameters include pH, conductivity, and temperature. Field <br /> parameter instruments will be calibrated before initial measurements and as needed <br /> throughout the day as required to maintain instrument accuracy. <br /> 8.2 Field Quality Assurance/Quality Control Samples <br /> The primary sample and field quality control samples are listed in Appendix C. Quality <br /> control samples will include field duplicates, field blanks and rinsate samples. QA/QC <br /> samples help identify potential sources of sample contamination and help evaluate <br /> potential error introduced by sample collection and handling. All QA/QC samples will <br /> be labeled with QA/QC identification numbers (i.e., "02" for duplicate samples, "03" for <br /> field blanks, "04" for rinsate) and sent to the laboratory with the other samples for <br /> analyses. <br /> Loveland Ready-Mix Concrete,Inc. 4 Telesto Solutions, Inc. <br /> 20180227_trr„_i:,pone_r,_ap re,I do- February 2018-REV] <br />
