Featured Video: Radionuclide Removal
Radionuclides are radioactive particles. They can be manmade or natural, existing in water, earth, and even living creatures. When they're consumed in drinking water, they can cause cancer or kidney problems. The USEPA has established drinking water standards to make sure radionuclides stay below dangerous levels in drinking water. If you're in an area with high levels of naturally occurring radionuclides, you are probably already aware of the issue and working to address it. But seeing how other small utilities are dealing with the same issue can still be useful.

In this week's video, the chief operator of the drinking water plant for Medicine Bow, Wyoming discusses the radionuclide treatment for his community, using a combination of ion exchange and blending. You might need to crank up the sound to catch everything, but it's still a great look at one small community's approach to this drinking water standard.



For more on the Radionuclides Rule, see the USEPA's Rule and Compliance pages, and this small system compliance guide in particular. You'll also find materials in our document database under the category Radionuclides.

Featured Video: Lime Softening Techniques for Water Operators

Hello, and Happy Friday! After the longer water treatment video last week, here is a little water treatment bite. In this 2-minute AWWA video, Fred Bloetscher briefly describes the process for adding lime to the reactor at a large drinking water treatment plant. He also demonstrates how quickly the lime reaction works to clarify the water.

Featured Video: Direct and Conventional Filtration

A new year is often a time of reflection, re-focusing, and a return to the basics. Even if you're not someone who believes in New Years' resolutions, the turn of the calendar year can still be a great time to consider the big picture and the details in it that are important to you. If you have a little time now that the holidays are over, this can also be a great time to brush up on your drinking water treatment knowledge. This 23-minute video is a walkthrough of a direct filtration plant, but it's a lot more than that. Ty Whitman of The Water Sifu explains each treatment step in detail while providing video of the flash mix process, flocculation basins, gravity filters, backwashing, and the spent washwater reclamation process. He also discusses the differences between the direct filtration processes he's demonstrating and conventional filtration.
