Among the Best & the Brightest: The 2002 WC&P Technical Review Committee

By Carlos David Mogollón,WC&P Executive Editor


It’s often difficult to enlist professional help. Dealers struggling to hire, train and keep good water treatment
technicians in the economic boom of the mid- to late-’90s—when joblessness held court below theoretical full employment for an extended period—no doubt can relate to that.

WC&P is fortunate in that regard when it comes to its Technical Review Committee. We’ve consistently been able to attract experienced, qualified and talented professionals in the point-of-use/point-of-entry water treatment industry to the group we affectionately call “TekRevu.”

This is the seventh year for the committee. The magazine relies heavily on members’ expertise and professionalism to guide it through the often turbulent tides of a market in transition. The committee helps us keep up with changes and enables us to put it into perspective for the residential drinking water improvement dealer to guarantee the impact on their livelihood is a positive one.

The committee’s background includes disciplines in ion exchange; reverse osmosis; ozonation; ultraviolet irradiation; spiral wound, composite, carbon and media filtration; distillation; aeration; bottled water, coolers, water vending and water stores; waterborne pathogens; commercial/light industrial; small systems and water well technology.

While membership is honorary, the committee is anything but idle. Members review technical articles, help recruit authors and write as well. They answer many of the questions posed to the magazine via our “Ask the Expert” column. And they take part in the annual WC&P Water Quality Roundtable at the Water Quality Association Convention & Exhibition.

We’d like to thank the following people who agreed to serve on the committee, as well as those who in the past year served as informal sources of technical information, such as Mike Gottlieb, Paul Overbeck, Kathy Ransome, Joe Harrison and Tom Sorg.

Here’s the 2002 WC&P Technical Review Committee.
