How long is the hold time for THM samples?

The hold time for Total Trihalomethane (THM) samples is 14 days. This duration is critical because THMs are volatile compounds, meaning they can degrade or dissipate if a sample is not processed or preserved adequately within this timeframe. By adhering to the 14-day hold time, laboratories ensure the integrity of the sample and the accuracy of the test results.

Understanding the importance of timely analysis aids in effective water quality monitoring and regulatory compliance, as THMs can pose serious health risks if their levels exceed regulatory limits. The hold time of 14 days allows for ample opportunity to conduct the required analyses without compromising the reliability of the findings.
