AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
Specification would help increase water efficiency in the commercial, institutional sectors
The U.S. Environmental Protection Agency (EPA) released a notice of intent (NOI) to develop a WaterSense specification for flushometer valve toilets. This would help increase water efficiency in the commercial and institutional sector. The NOI describes the efficiency and performance criteria WaterSense is considering including in a draft specification, as well as the technical issues that still need to be more fully defined and resolved.
Tiny pores in graphene offer possibility of membranes that filter microscopic contaminants from water
Much has been made of graphene’s exceptional qualities, from its ability to conduct heat and electricity better than any other material to its unparalleled strength. Previous research has also shown that pristine graphene — a microscopic sheet of carbon atoms arranged in a honeycomb pattern — is among the most impermeable materials ever discovered.
Nothing is constant except change itself. Water coolers and water vending machines are not exempt from this old adage. Think of a water cooler. What comes to mind? Most typically, a picture of the standalone device that has a 5-gal bottle of “purified” water positioned on the top. These types of coolers would serve cold, ambient or hot water.
When the bottle would run low on water, miraculously a stranger would show up and replace the bottle with a fresh, new bottle. A continuous source of tasty water at your desired temperature.
