Making the Filtration Buying Process Easier for Your Customers   Water Quality Products March 2002   By David M. Marsh
If you’ve seen it once, you’ve seen it a hundred times—customers who come to you looking for a home filtration system, unaware of what their specific needs are.

It also removes hydrogen sulfide from ground water (wells and springs) and eliminates iron bacteria (cenothrix), which are associated with objectionable odor and taste.

Legionella Management and Monitoring: Part 2   Water Quality Products February 2002   Paul S. Warden, Kristen S. Fallon, Ph.D., M.S.E.L., & Colin R. Fricker, Ph.D.
Well-designed water distribution and cooling systems, coupled with sound management and operational procedures, are essential to control Legionella in industrial facilities—and a monitoring program should not be considered as a replacement. However, most experts even those ill-disposed towards routine Legionella monitoring, would agree that monitoring should be considered if enough legionellosis risk factors apply to the system in question. No management program, regardless of its treatment, maintenance or monitoring components, can guarantee the absence of future legionellosis, but prudent operational practices combined with ongoing review of risk factors will allow facility managers to minimize exposure to Legionella and to its legal consequences.
