There are two things humans cannot live without: air and water. While in the developed world we know them to be seemingly plentiful, in nearly every region both are polluted to some degree. Industrialized nations have learned (for the most part) to put processes into place to prevent the ubiquitous pollution but even they must contend with the constant threat of emerging contaminants. It’s in this framework of cause and effect that the water treatment industry must operate to find the best and safest solutions to water quality issues. But it isn’t an easy task.

In addition to known threats to water safety, there are a host of issues that are creeping to the forefront of industry consciousness, namely a multitude of unregulated contaminants, the push to go green and the need for sustainability. Some of the goals are bound to come into conflict because there are so many approaches for overcoming the problems. Long the backbone of water treatment, chemistry is now being looked at more closely as it relates to the use of plastic, nano materials and other latest-and-greatest products that are creating both intended and unintended consequences.

Peter Cartwright, PE, provides a fascinating two-part article on the contaminant of the month and those yet to emerge as well as what can be done to mitigate the problems that arise. The first part goes in depth to define what is known about water and chemistry and what is only now beginning to come to light. Why was something vaunted as the next big thing in plastics now touted as an environmental crisis? There is no easy answer, though Cartwright leads us through what works in water treatment, as well as the disadvantages that are now being seen.

No system has yet been created and produced that does not need some measure of maintenance. One of the biggest culprits in water treatment is keeping all the parts in working order to ensure a level of consistently high cleanliness. This is a difficult premise when biofilm is part of the problem. Greg Reyneke of Red Fox Advisors presents the whys and wherefores of system sanitization for both timed maintenance intervals as well as yearly schedules. It cannot be stressed enough that no system is maintenance-free!

Dr. Kelly Reynolds, Public Health Editor, reviews the growing acceptance of potable reuse water on a global scale. The many methods for reuse may help offset the problems associated with water scarcity that now threaten the entire world. It’s not a developing nations issue any longer.

As we approach the end of the calendar year, convention season is still going strong. We hope to see you often, at upcoming conventions and trade shows and if not, drop us a line and let us know how we’re doing. If you want something covered, tell us what is missing from our coverage and we’ll try to be as inclusive as possible. On a side note, we’ve changed the groundwater/arsenic topics to the November issue and moved desalination/wastewater to December. If you have an unpublished white paper or want to write on those topics, by all means, get in touch. We’re always looking for talented industry experts to help us inform our readers!
