What is the hold time for BACT samples from the distribution system?

The hold time for Bact (Bacteriological) samples from the distribution system is critical in ensuring the accuracy and reliability of the test results. For Bact samples, the specified hold time is 30 hours from the time of collection to analysis. This is established to maintain the viability of the microorganisms being tested, which is essential for accurately detecting the presence of pathogens or coliform organisms in the water supply.

If samples are tested beyond the 30-hour window, there is a risk that the bacteria may die off or multiply, leading to potentially misleading results. This is especially important in a drinking water context, where the safety and health of the public are paramount. Adhering to this 30-hour timeframe ensures regulatory compliance and helps maintain water quality monitoring standards.
