How to Ensure Quality Control in Environmental Sampling?
Quality control (QC) measures are essential to ensure the reliability and accuracy of environmental sampling:
1. Standard Operating Procedures (SOPs): Following SOPs for sample collection, handling, and analysis reduces variability and errors. 2. Blanks and Duplicates: Using field blanks, trip blanks, and duplicates helps identify contamination and ensure precision. 3. Calibration and Maintenance: Regular calibration and maintenance of sampling and analytical equipment ensure accurate measurements. 4. Chain of Custody: Maintaining a chain of custody for samples ensures their integrity from collection to analysis.
