The article discusses how the performance of an on-line automated trihalomethane monitor is as accurate and precise as off-line commercial laboratories. The US Environmental Protection Agency (USEPA) has estimated that public water systems will need to spend $4.2 billion to upgrade their water treatment infrastructures and achieve compliance with the Stage 2 Disinfectants/Disinfection Byproducts Rule (D/DBPR). Infrastructure upgrades could include improvements to coagulation, filtration, and disinfection systems and supplemental trihalomethane (THM) remediation in storage and distribution systems. Without-real-time accurate THM measurements of their processed water at both the plant and in distribution systems, THM safety margins must be factored into their processes, making it difficult to optimize THM levels in the face of the other resource constraints.
