At what temperature is the Maximum Total Trihalomethane Potential (MTP) measured?

The Maximum Total Trihalomethane Potential (MTP) is measured at 25 °C, which is established as a standard reference temperature in many water quality assessments. This specific temperature is significant because it helps to ensure consistency and reproducibility in measurements taken across various studies and tests. Measuring MTP at 25 °C allows for better comparison of results, since temperature can influence the formation of trihalomethanes (THMs) during chlorination and other water treatment processes. At this temperature, the reactions that form THMs reach a reliable and comparable level, which aids in understanding their potential impact on water quality and public health.
