IDEM Minimum Data Documentation Requirements
February 13, 2003
General requirements applicable to all samples are followed by requirements specific to analysis type.
Table of Contents
General Requirements for All Samples
Sampling Quality Control Data and Information:
- Chain-of-Custody
- Date and time each sample was taken
- Map or diagram indicating sample locations
- Any notable observations (color, clarity, texture, reaction with preservatives, etc.)
- Trip blank (or field blank)
- Equipment blank (rinsate blank)
- Identity of field duplicates (a minimum of one duplicate for every 20 or fewer samples)
- Sample for site specific MS/MSD
Laboratory Quality Control Data and Information:
- Completed Chain-of-Custody
- Date and time of receipt at the laboratory
- Condition of samples upon receipt at the laboratory
- Sample identification number or designation
- Sample preparation, extraction, cleanup, or digestion method(s) and date(s)
- Analytical method (name, number, and source) and date of analysis
- Final analytical results
- Case narrative (Includes deviations from standard analytical or preparatory procedure(s); quality control problems encountered--whether stemming from system, instrumentation, analyst error, or sample matrix; corrective measures taken; if corrective measures as called for in the method were not taken; results of corrective measures taken; etc.)
Specific Requirements by Analysis Type
Organic Analyses
Volatile Organic Analysis (VOA) and Semivolatile Organic Analysis (SVOA)
by Gas Chromatography/Mass Spectrometry (GC/MS)
- Method blank summary sheet with results, including detections
- Detection/quantitation limit for each compound
- Internal standards summary
- Surrogate (System Monitoring Compound) results (concentration of surrogate spikes added, measured concentrations, and % Recoveries of all surrogates) for each sample
- Matrix Spike/Matrix Spike Duplicate (MS/MSD) results (sample concentration for analyte, concentration of spike added, results, % Recovery for each compound, and Relative Percent Difference between MS and MSD for each compound)
- Laboratory Control Sample results
Analysis of Volatile Organic Compounds and Semivolatile Organic Compounds by
Gas Chromatography (GC) Using Method-Specified Detectors (FID, PID, HECD, etc.) and Analysis of Semivolatile and Nonvolatile Organic compounds by High Performance Liquid Chromatography (HPLC)
- Method of sample introduction (direct injection or purge-and-trap)
- Detection/quantitation limit for each compound
- Method blank summary
- Surrogate recoveries for samples, blanks, and spikes
- Matrix spike/matrix spike duplicate (MS/MSD) analysis or lab duplicates
- Laboratory Control Sample results
Analysis of PCBs by Gas Chromatography (GC) with Electron Capture Detector (ECD) or Electrolytic Conductivity Detector (ELCD or HECD)
- Method blank summary
- Detection/quantitation limit for each compound (in each sample)
- Surrogate recoveries for samples, blanks, and spikes
- Matrix spike/matrix spike duplicate (MS/MSD) analysis or laboratory duplicates
- Laboratory Control Sample results
Metals and General Chemistry Analyses
Total and Dissolved Metals by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP) or Atomic Absorption Spectroscopy (AA) and General Chemistry Analyses
- Method/sample quantitation limits
- Instrument detection limits
- Blank results
- Matrix spike (sample number of sample spiked, sample concentration for analyte, concentration of spike added, results and % Recovery)
- Matrix spike duplicate or laboratory duplicate (results and Relative Percent Difference [RPD]; if matrix spike duplicate, also report %Recovery)
- Laboratory control sample (QC standard or lab-fortified blank: results and %Recovery).
