6. Decontamination In Days: How Calgon Carbon Cleaned Pearl Harbor 8/11/2023

   A first-hand account of how Calgon Carbon Corp. executed a last-minute clean jet fuel contaminated water around the Joint Base Pearl Harbor-Hickman.

7. VOCs For Non-Scientists: Understanding, Detecting, Removing 3/14/2022

   This introduction to volatile organic compounds (VOCs) will discuss what qualifies a compound as a VOC, how to detect them, and how to treat and remove these chemicals from the water system.

8. Minimizing Disinfection Byproducts By Targeting Natural Organic Matter Precursors 3/4/2022

   Water treatment plants (WTPs) need to lean less on the disinfection process strategies (i.e., chloramination) and instead focus on more comprehensive DBP solutions such as removing TOC. Here's why.

9. Refining GAC Solution Costs For PFAS And Other Contaminants 2/3/2022

   Whether a water treatment plant (WTP) is evaluating a new granular activated carbon (GAC) solution to deal with contamination problems such as PFAS, DBPs, and VOCs or looking to enhance existing GAC performance, it is important to assess treatment processes in the full context of source water quality. Here are some ideas to help decision-makers achieve the best outcomes at the lowest total lifecycle cost.

10. Optimizing PFAS Removal In The Presence Of Other Contaminants 1/19/2022

    Here are some considerations that can help water treatment plant (WTP) supervisors, operators, and their consulting engineers achieve their PFAS removal goals more efficiently and cost effectively despite the added challenges.
