An email publication of the Pure Water Gazette
The Pure Water Occasional is an 
email publication of the online news magazine, the Pure Water Gazette. The Occasional's content varies greatly. Water and water treatment are the central focus, but when you really look at the world you see that everything is about water. So anything goes.
The site serves as home for back issues of the of the Occasional, arranged so they can be easily accessed.
There is also a healthy archive of information, all of it about water-related topics. We make no distinction between the technical and the popular. You may find information about how to remove hydrogen sulfide from well water beside a piece about Handel's water music or Madonna's favorite brand of bottled water.
There's no advertising except our sponsor's, and we don't trade links. If we link to someone else's website, it's because we think it would be worth your consideration.
This site is also the home of three significant series of water treatment articles:
The How It Works series examines familiar but sometimes misunderstood devices used in water treatment. If you've ever wondered how a reverse osmosis unit, or a permeate pump, or an air gap faucet works, this is the place to look.
The Water Treatment Issues series focuses on specific issues that are targeted by water treatment. Note that the topics are "issues," not contaminants, although many of the issues discussed are indeed common water contaminants. Low pH is an issue that is frequently addressed in water treatment, but it isn't, properly speaking, a contaminant.
The Water Treatment Methods series examines specific water treatment methods, focusing on the methodology of water treatment rather than symptoms. For example, how hydrogen peroxide or soda ash are used to treat water.
Other sections include a great and growing page of active links to water treatment and general water information websites. As stated above, we do not trade links, so the sites included are sites we feel are worthwhile. There's also a section describing the newest products to appear on our sponsor's commercial sites.
The financial sponsor of both the Pure Water Gazette and its offspring the Pure Water Occasional is Pure Water Products. Pure Water Products sells a large variety of water treatment equipment, and you'll see a link to its main website from time to time as well as satellite websites that offer specific products in greater detail.

The Occasional is edited by Hardly Waite and shares staff with the Pure Water Gazette. Veteran Pure Water Gazette columnists Tiger Tom and B. Bea Sharper are contributors. Owner Pure Water Annie is also a regular contributor of technical articles.
As new issues of the Occasional appear, they are archived on this site.
The current archive goes back to 2009.
