What does this live ticker show me?

The live data feed displays the date and local time (PDT) the reading was received and identifies the concentration of TTHMs or THM-FP measured in parts per billion (ppb). THM-FP is the measurement of water quality characterizing the maximum quantity of THMs that can be formed over time.

The U.S. Environmental Protection Agency permits a TTHM maximum level of 80 ppb, based on the average of four quarterly (every three months) readings at specified points in a utility’s water distribution network.

  • When TTHM/THM-FP concentration levels are well within regulatory compliance and below 60 ppb, the ticker will display TTHM/THM-FP data in green.
  • When TTHM/THM-FP concentration levels reach 60 ppb the ticker display will change to orange to alert that the water supply has the potential to exceed the regulatory compliance.
  • When TTHM/THM-FP concentration levels increase to 80 ppb the ticker display will change to amber to alert that the water supply has exceeded the regulatory compliance.

The Value of Real-time, Online THM Data

THM levels are affected by several factors: changes in the quality of the water which can be brought on by drought or sudden rainfall or variations in the source of the water; by temperature; by the quality of drinking water storage tanks and pipelines; and by the physical time it takes for the water to reach the consumer. It is very difficult for water suppliers to predict what THM levels will be found across their system at any one point in time when there are so many variables that may have an impact.

This is where the value of the online THM-100 monitor comes in!

The THM-100 analyzer provides accurate and reliable results on four THM species as well as TTHM in less than 120 minutes and THM-FP in approximately 180 minutes. The analyzer’s unique capability to online predict THM-FP enables optimization of THM mitigation processes based on future levels of THMs in the distribution network. With the online THM-100 monitor water utilities can proactively manage their THM mitigation strategies and ensure that their water remains safe for human consumption.
