A pilot study conducted by the Los Angeles County Waterworks District has been named “Outstanding Water/Wastewater Treatment Project of the Year” by the American Society of Civil Engineers’ Metropolitan Los Angeles Branch.
The six-month study identified a new, cost-effective way to reduce harmful pollutants in water supplies. Using aeration technology, Waterworks successfully lowered concentrations of total trihalomethanes (TTHM)—a natural byproduct of the water disinfection process—by 80 percent in a test tank. According to the United States Environmental Protection Agency, prolonged exposure to TTHM may be linked to cancer and other health risks.
- The system is among the first of its kind in California.
- The system is very cost effective compared to granular activated carbon filters, an energy-intensive alternative that would require the construction of extensive new facilities.
- Waterworks plans to install the cutting-edge system in Malibu later this year.
The award will be presented at the Branch’s 2015 Awards Dinner on Friday, August 14th.
