Northern Kentucky Water District to Incorporate an Online THM Analyzer Into Stage 2 DBPR Compliance Strategy
The Northern Kentucky Water District has purchased the online THM-100™ THM analyzer from Aqua Metrology Systems to monitor daily THM levels in their distribution network and further enable optimization of treatment processes used to minimize the formation of THMs in treated water.

AMS Introduces an Online THM Analyzer to Accommodate Multiple Sampling Points With Single Instrument
Monitoring real-time THM levels across multiple sampling points within a drinking water system using a single instrument is now possible with the THM-100GS™ analyzer from Aqua Metrology Systems. The THM-100GS is a new version of the standard online THM-100 system. The new analyzer enables a utility to carry out automated analysis of manually collected “grab samples” across their network.

The Value of Instrumentation In The Water Industry
As long as instrumentation is selected, installed, commissioned, and maintained properly the data that it can give is invaluable to the water industry. However, there are a number of barriers in the way… read the rest of the article and a response from Rick Bacon the CEO of AMS.

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.

The dangers caused by the enormous wildfire near California’s Yosemite National Park are clear to anyone who has seen the dramatic videos and photos. But a fire that has already razed an estimated 134,000 acres of land in nine days and is only twenty per cent under control holds an even greater long-term threat to the drinking water supply, as the Hetch Hetchy reservoir adjacent to Yosemite provides drinking water to over 2.6 million residents in the San Francisco Bay Area.
Ash falling into Hetch Hetchy significantly increases the amount of organic material in the source water and post disinfection, an increased level of carcinogenic Trihalomethanes (THMs) in the drinking water supply, while fire-suppression chemicals kill fish and contaminate the aquifer and increased solids clog filters.
Unfortunately, most consumers will not know whether their water is safe because of the time taken for laboratories to analyze drinking water samples from their city´s water utility by which time millions of gallons of water will have been already piped to them.
Fortunately, there is already a tried and tested solution installed in a number of Northern California water utilities, in the form of the THM-100, a fully automated system developed by Sunnyvale based Aqua Metrology Systems (AMS) that provides real-time data of the THM levels in a city’s water supply and can alert water utilities and consumers immediately if there is a problem so the water utility can take preventative actions. The Californian cities of Sunnyvale and Benicia are examples of the early adopters of this technology and their water quality readings can be seen at www.tthmalert.com
Rick Bacon, CEO of Aqua Metrology Systems, commented
“While the devastating Yosemite fire raises serious challenges about the ensuring the safety of drinking water over the coming weeks, the fact that THM levels can be monitored in real-time year round will give consumers confidence their water is safe to use before they do so”

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.
