The City of San Angelo, TX selected WRT’s Z-88® Radium Removal treatment system for reducing high levels of radium in their wells. The city’s Phase I treatment plan was fulfilled in 2014 with the installation of the first Z-88® Radium Removal treatment system. This large treatment facility has been reducing the levels of radium below the Maximum Contaminant Level (MCL) since it’s inception.
Following a disaster like the back-to-back hurricanes that hit Texas, Florida, and Puerto Rico in 2017, water systems can become flooded and unable to provide safe drinking water to communities. EPA researchers recognized the need for portable water treatment systems that can quickly and cost-effectively provide safe drinking water to affected communities following a disaster.
In the 1990s, the City of Wichita, KS, developed a water supply plan that included creating a sustainable water supply through the year 2050. The key component of the plan is recharging the large aquifer that lies under the region with 100 MGD of water from the Little Arkansas River.
Located in northern California, the Coastside County Water District (CCWD) provides treated water to the scenic town of Half Moon Bay and several unincorporated communities in the area. The system is served by two treatment plants, the Nunes Water Treatment Plant (4.5 MGD) and Denniston Creek Water Treatment Plant (1.0 MGD) and water is distributed through about 100 miles of transmission and distribution pipe.
WRT’s Z-88® Radium Removal treatment system was selected to remove high concentrations of radium in two treatment facilities for the City of Bridgeton, NJ. Both treatment facilities are now producing safer drinking water since the installation of the Z-88® Radium Removal treatment systems in 2009 and 2010.
Located in Northern Missouri, the city of Trenton and its more than 6,000 residents pride themselves on self‐sufficiency and pragmatic decision making. During the spring of 2012, the utility embarked on the design and construction of chemical feed system upgrades at the existing water plant that would help the city manage the need for new capacity, better control of trihalomethanes (THM’s) and improve operator safety by removing gaseous chlorine as a disinfectant.
National Lead Poisoning Prevention Week marks a time when EPA and our federal partners promote education and awareness activities that focus on lead and how to prevent its negative health effects. This year, we focus on the theme, “Lead-Free Kids for a Healthy Future.” It’s through our joint efforts that we have been able to make significant strides in reducing exposure to lead over the past several decades.
The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.
Hendersonville Utility District (HUD) serves one of the most populous suburbs of Nashville, Tennessee.
When the City of Midlothian, Texas, was ready to expand their water treatment plant to accommodate a growing population, they carefully considered and investigated their water disinfection options.
