• Uniform sampling containers (i.e. containers that are supplied, constructed, cleaned and <br /> prepared identically); <br /> • Standardized forms and/or electronic data storage devices for recording field and <br /> analytical data, prepared sample identification tags, and Chain-of-Custody (COC) <br /> records; <br /> • Field team performance observations; <br /> • Field and laboratory instrument performance; <br /> • Standardized protocols for field and laboratory instrument calibrations using certified <br /> standard solutions; <br /> • Data documentation audits to determine data adequacy; and <br /> • Known and validated uncertainties for field and analytical data. <br /> 1.8.4 Data Completeness <br /> Completeness is defined as a measure of the amount of valid data obtained from a measurement <br /> system compared to the amount that was expected under correct normal conditions. Field sampling <br /> conditions are unpredictable and non-uniform. Other problems affecting field completeness will be <br /> equipment/instrument malfunctions and problems with sample recovery. These problems will be <br /> reduced by training field team members to perform basic repairs and by supplying spare pans and <br /> equipment at the field site. <br /> Analytical completeness is affected by a sample not analyzed before its holding time is expired; if it <br /> is damaged during handling, shipping, unpacking, or storage; or if the laboratory data cannot be <br /> validated and the sample cannot be reanalyzed. <br /> Critical samples are those samples that are essential to the successful completion of the project. The <br /> completeness goal for crucial samples is 100%. The project team will present any deviation from <br /> the sampling plan. <br /> 1.9 Special Training Requirements <br /> No special training requirements or certifications are required for this project except for the 40-hour <br /> HAZWOPER class and annual refreshers. Resumes of CGRS personnel who may be involved with <br /> this project are presented in Attachment A. <br /> 1.10 Documentation and Records <br /> Activities that affect data and data quality and that potentially will be used as evidence will be <br /> documented. The project manager will maintain a supply of and will control these documents. The <br /> following documents will be used if appropriate: <br /> ➢ Sample labels; <br /> ➢ Chain-of-Custody records; <br /> Sample analysis request sheets; <br /> ➢ Electronic data storage devices and/or field logbookst <br /> Calibration logbooks: <br /> ➢ Shipping logbooks; <br /> iol SAPS; <br /> ➢ QAPP; <br /> > Progress and interim reports, <br /> Varna Companies <br /> Quality Assurance Project Plan <br /> Page 5 <br />
