Heptachlor epoxide, trichloroethane, aesthetic chlorine, acrylonitrile, TDS, xylenes, lead, arsenic, hexachlorocyclopentadiene … Certainly, some of the chemicals listed above are recognizable not only to you but also to the average consumer. Some of them are recognizable to you, but the average consumer would stumble through their pronunciation. Should you consider certifying the contaminants listed above?
Deciding which contaminant reduction claims to certify
As water coolers evolve to include more complex point-of-use filtration systems, certification becomes increasingly important. Dave Bentley, technical manager for NSF Intl., recently discussed the ins and outs of cooler certification with Water Quality Products Managing Editor Kate Cline.

“Arsenic Found in Groundwater.” How many times have you seen that headline? There is no doubt that arsenic has become a common household term, used not only by teenagers studying the periodic table but also by adults who have long forgotten their high school chemistry classes.
In the last 10 years, arsenic has made headlines for various reasons. Most deal with human exposure and its associated risks.
Arsenic is present in natural deposits in the earth. It can enter drinking water supplies from these deposits or from agricultural and industrial activities.

NSF Passport Program helps manufacturers gain global market access for water treatment, distribution and plumbing products
NSF Intl. has named Dr. Guy Franklin as the new managing director of the recently launched NSF Passport Program, which helps companies gain global market access for water treatment, distribution and plumbing products.
The program will be eliminated after December 31 of this year
On April 6, the California Department of Public Health (CDPH) announced that it would be abandoning the drinking water unit certification program after Dec. 31 of this year.
The decision came after lengthy discussions with the Water Quality Assn. (WQA) and after the association introduced legislation to turn over certification responsibilities to American National Standards Institute (ANSI)-accredited third-party certifiers such as NSF Intl. and WQA.
Recently I learned that fire hydrants use a color-coding system to indicate the flow rate a hydrant can deliver. Hydrants with light blue-coated bonnets and nozzles deliver the fastest flow rates, 1,500 gal per minute (gpm) or greater, while hydrants with red-coated bonnets and nozzles deliver 499 gpm or less. Coatings are amazing products—not only are they aesthetically pleasing, they also provide surface protection or improvement and can convey important information to the end user.

Choosing the right drinking water treatment product is not easy. There are many factors to consider prior to installation. Water characteristics, family members, price and certification by a reputable organization all are important. Share these factors with your clients to help them choose the right treatment system for their homes.
Factors in choosing the right water treatment system
Like assembling a jigsaw puzzle, regulations for drinking water products must be understood and put together correctly to find a solution and see the entire regulatory picture. Unfortunately, the pieces can be difficult to assemble.
Certification programs help navigate complex international standards
According to statistics published by the U.S. Environmental Protection Agency (EPA), water coolers across the U.S. consume about 6 billion kWh of electricity per year.1 Some water coolers actually use more energy than a refrigerator.
Lowering energy costs with efficient water coolers
Lead has been a hot topic for consumers and the media for many years. We all have heard about the deterioration of U.S. water distribution systems, lead service lines, extremely high levels of lead in Washington, D.C.’s drinking water because of a change from chlorine to chloramine, lead in paint, lead in toys, new lead content laws in California and Vermont (soon to be national)—concerns about lead that will never go away.
