41. GAO Report Promotes New Way To Advance LSL Remediation 1/25/2021

    In a report released just days before the U.S. EPA issued its final revisions to the Lead and Copper Rule (LCR), the U.S. Government Accountability Office (GAO) provided insights that water utilities can use to achieve better protections for water customers in neighborhoods at higher risk of lead exposure. Here is a peek into its four recommendations, which the GAO anticipated updating in response to the EPA final LCR revisions.

42. Case Study: Ambitious Water Quality Study Could Guide Development For Years 5/25/2006
    The City of Kissimmee, Fla., has embarked on an ambitious water quality study that could provide a road map for development in the fast-growing tourist mecca – and save millions of dollars as the city begins to comply with water quality regulations
43. The Right Choice For Environmentally Friendly Pipe Installation 6/30/2014

    Like several of its counterparts in Florida, Pasco County is a name frequently repeated in the news when it comes to growth.

44. Know Your Options For Mag Meter Installation Cost, Care, And Calibration 7/2/2019

    Electromagnetic meters (mag meters) are well established in terms of highly accurate performance for a variety of municipal and industrial water applications. Differences in their construction formats, however, dictate how easy they can be to install, maintain, and calibrate. Compare these three options to see the value of full-profile-insertion (FPI) mag meters and their associated advantages in real-world use.

45. Adaptive Mixer Helps Water Reuse Facility Avoid Costly Treatment Operation Shutdowns 2/24/2023

    Discover how innovative mixing technology resolved constant build up and settling of lime softener sludge for a water reuse facility. 

46. Radium Removal For A Large Treatment System 8/9/2018

    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.

47. The End Is Near For FOG Deposits 10/18/2013

    DO2E has designed and patented the "Little John Digester" for complete removal of FOG deposits of FOG deposits and H₂S waste water.

48. EPA Scientists Test Non-Targeted Analysis Methods Using Drinking Water Filters 5/19/2021

    Today, researchers can rapidly search for thousands of never-before studied chemical compounds in a wide variety of environmental, residential, and biological media. This approach is called “non-targeted analysis” (NTA). It differs from targeted analysis because researchers do not have to know what specific chemical they are looking for in a sample. They can use high-resolution mass spectrometry (HRMS) to rapidly identify many of the chemicals present in a sample. The HRMS measures the accurate mass of molecules and can find chemicals that would have gone unnoticed before. This approach is beneficial not just to researchers, but to States, tribes, and local communities who might want to know more about chemical exposure.

49. Pilot Test For Manganese Removal Using Manganese Greensand 10/11/2018

    Filtration rates, run times, backwash procedures, chemical dosage rates, etc. are all established by theoretical calculations and history. Therefore, Loprest’s goal in this pilot study was to conduct uninterrupted operation per bid testing procedures and document the results.

50. In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility 6/16/2016

    To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.
