Application Brief: Central Texas Water Supply Corporation Manages DBP Formation with Help from Online THM Analyzer
The Central Texas Water Supply Corporation has incorporated an online trihalomethane (THM) analyzer, THM-100™, at their WTP to help manage DBP formation. The THM-100 is a viable tool, among others, that enables plant operators to have a firm and immediate understanding of water quality leaving their plant and throughout their distribution network.

The City of Benicia, California, implemented a series of best management practices to help minimize the formation of trihalomethanes (THMs) in their distribution system and ensure regulatory compliance. In addition to minor pre-treatment and disinfection process changes, the Benicia Water Treatment Plant (WTP) decided to monitor THM levels more frequently using the online THM analyzer, THM-100™, to provide accurate and timely information regarding THM levels in their treated water. Integrating the online THM-100 analyzer at Benicia WTP has become an essential element to help support the delivery of treated water of the highest quality.
Application Brief: Online THM Monitoring Helps New Jersey Water Authority Achieve DBP Compliance
An online trihalomethane (THM) analyzer, THM-100™, was installed to monitor THM levels at The Old Bridge Municipal Utilities Authority (Old Bridge MUA) serving the township of Old Bridge, Middlesex County, New Jersey. The utility learned that quarterly DBP compliance measurements are inadequate for understanding actual DBP levels within the water distribution system; since DBP levels can range significantly, even within the same day. However, through frequent and effective direct THM monitoring, as provided by the THM-100 analyzer, they could establish a baseline and optimize DBP management processes managing compliance to the Stage 2 DBP Rule.

SafeGuard™ is an automated trace metals analyzer for monitoring municipal and industrial water and wastewater. The system provides real-time, multi-stream analysis for trace metal contaminants.
SafeGuard delivers accurate and reliable results (up to 1 ppb or ± 15%, whichever is higher) with a typical measurement time of fewer than 30 minutes. An enhanced system is available with a fast turn around time of 5 minutes without compromising accuracy. The analyzer can be used to measure up to two different trace metals contaminants on the same instrument.
Trace Metals
Contaminants such Arsenic, Chromium-6, Lead, and Selenium have come under increased regulatory pressure due to their impact on public health and the environment. The ability to obtain high frequency data and adjust contaminant remediation processes in real‐time to mitigate the impact of trace metals is only made possible through the use of the online MetalGuard™ and SafeGuard™ analyzers.
Disinfection By-products
Reliable data on THM and THM Formation Potential concentrations is required to mitigate the presence of harmful DBPs and monitor the success of THM remediation processes. Accurate and real‐time data on THM concentrations is only possible with the online THM‐100™ analyzer.
