1. World's Largest 1,4-Dioxane Treatment Initiative 9/9/2024

   Groundwater on Long Island, New York, contains the contaminant 1,4-dioxane. Despite no federal regulation, local water providers and state authorities have taken action to address contamination, establishing a state-enforced maximum contaminant level.

2. How And When The EPA's Proposed PFAS MCLs Could Impact The Drinking Water Industry 3/22/2023

   The U.S. EPA recently announced its proposal for what would be the first-ever national drinking water standards for PFAS. This news likely triggered several questions about what this means to the drinking water industry. Here, we will address some of the most important ones.

3. How To Ensure Your Utility Complies With The LT2 7/25/2016

   The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?

4. Treatment Of Cyanotoxins In Drinking Water With Activated Carbon 9/24/2014

   Recently, cyanobacteria and cyanotoxins have become a high profile drinking water quality concern in both the United States and abroad. The combination of weather conditions, agricultural phosphate runoff, and other factors has produced water conditions that have favored the formation of cyanobacteria in surface water supplies.

5. The Many Faces Of Carbon — A Versatile Treatment Solution 8/13/2014

   What concerns drinking water municipalities the most? Is it regulations, emerging contaminants, or a crisp, clear product? To a degree, it’s all of the above. Jim Knepper of Jacobi Carbons explains.

6. North Las Vegas Puts Advanced Wastewater Treatment To Work 12/13/2021

   The North Las Vegas Water Reclamation Facility treats an average of 17 million gallons a day (MGD) of wastewater through an advanced nutrient removal process with subsequent membrane filtration. The utility’s process control enables treatment effluent exceeding typical environmental standards and allows discharge to Lake Meade, where it subsequently is withdrawn and fully treated by other facilities for drinking water distribution.

7. Ion Exchange Resin Versus Granular Activated Carbon For Drinking Water Treatment 10/4/2024

   A cost-effective option for PFAS removal and MCL compliance is the addition of an ion exchange resin (IEX) treatment as a “bolt-on” to an existing DWTP.

8. Mixing Made Easy For Low Energy Lakes, Ponds, And Lagoons 6/29/2020

   Landlocked, shallow bodies of water such as recreational ponds, irrigation, drinking water and animal waste lagoons have a major problem with flow. The only natural methods of movement in these bodies of water are the slight Coriolis Effect of the earth and wind.

9. An Economical Approach To The LT2 Rule 4/8/2021

   Water Online spoke with Alfredo Rizo-Patron and Cyndi Benson of Harmsco Filtration Products about the factors that create the most problems for these communities as well as cost-effective options for achieving and maintaining compliance.

10. 5 Burning Questions On Uranium And Radium Removal 10/17/2016

    High levels of radionuclides (uranium/radium/etc.) in drinking water aren’t very common, but they are very dangerous. If you’ve long dealt with radionuclides, you’re familiar with the treatment requirements — but are you treating as cost effectively as possible?
