What is the main purpose of field duplicate samples?

The main purpose of field duplicate samples is to check the variability of the sampling technique and analytical test. By taking duplicate samples from the same location, environmental professionals can assess the consistency and reliability of their sampling methods. This process involves analyzing both the original and the duplicate samples to identify any discrepancies in the results.

Field duplicates help in understanding the precision of the sampling procedure, ensuring that any variations in results are noted and can be addressed. If the results of the duplicate samples are consistent, it increases confidence in the accuracy of the data collected. Conversely, significant differences may indicate potential issues with the sampling process or analytical methods, prompting further investigation and refinement.

This quality control measure ensures that decisions based on the data, such as risk assessments or remediation actions, are based on reliable information, ultimately leading to more effective environmental management.
