The buying and selling of treated water is common practice in the United States. Consecutive systems (CS) — public water systems that buy or receive some or all of their finished water from one or more wholesale systems (WS) — are responsible for serving nearly one-third of the water customers in the U.S… read the rest of the article by Rick Bacon the CEO of AMS.

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.

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.

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.

The largest water system in Alabama, has purchased an online THM-100™ THM analyzer from Aqua Metrology Systems to monitor daily THM levels at their Shades Mountain Filter Plant.

A THM-100 analyzer was installed to monitor the THM levels of the incoming water from the Middlesex Water Co. as well as the THM levels of the water leaving the tank.

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”
