The year started off with big news in the water treatment industry. The chemical spill in West Virginia, which affected more then 300,000 people, topped national headlines for weeks in January. The “do not use” advisory lasted more then a week for portions of that population, forcing them to rely on bottled water for drinking, cooking and bathing for up to 10 days.
Webinar will identify treatment technologies and equipment needed to mitigate recontamination
The Water Quality Assn. (WQA) will host its Mitigating Recontamination webinar on Feb. 5, 2014, at 2 p.m. EST. The webinar will explain where recontamination may occur and identify treatment technologies and equipment needed to mitigate recontamination. In order for your registration to be processed, it much be purchased no later than 5 p.m. EST on Feb. 4.
Nelsen Arsenic Reduction Systems feature the 7000PID (Nelsen proprietary controller) arsenic reduction control valve and LayneRT adsorption media. The 7000PID is a non-backwashing controller programmed for the specific water chemistry for each installation. It indicates system capacity and the remaining safe levels of media adsorption. LayneRT is a proprietary, durable, arsenic-selective media.
New best suggested practice developed for water well system professionals
The National Ground Water Assn. (NGWA) has developed an industry best suggested practice (BSP) for water well system professionals to use on how to deal with problematic concentrations of hydrogen sulfide in residential water well systems.
Just when you thought you had read enough about heavy metal in the Unger household and heavy metals in water, I am back! Last month I discussed the various challenge waters used for testing filters that make claims for heavy metals. These challenge waters are influenced by the various water supplies across the U.S.
Testing procedures for heavy metal removal certification
It’s a lazy Saturday morning at the Unger house. Mom is at work, and she left me and the kids (ages 11, nine, seven and five) a giant list of chores to complete while she is away. The problem is, we do not have much enthusiasm or energy to get them done — so what do we do?
Understanding the science behind heavy metal filtration certification
When most people think of rainwater harvesting, they picture a 55-gal tank that collects rainwater from the roof to water plants — but this term also extends to natural collection systems like dams. Rainwater harvesting is nothing new; it has been around for centuries, dating back to ancient Egyptians who used earthen dams to control runoff. Another example is the rice terraces of the Philippines, which are still in existence today. More sophisticated rainwater systems have been uncovered by archaeologists in Crete, Istanbul and throughout the Mediterranean region.
Regulation & contamination factors for potable rainwater reuse applications
Isaac Plains is an open-cut coal mine in northern Queensland, Australia, that operates under an environmental authority. One of the environmental monitoring requirements that must be met is water monitoring. This includes monitoring potable water, mine-affected water, natural creek flows, water releases, groundwater and the receiving environment.
Onsite testing technology helps mine meet water monitoring requirements
The Federal Reduction of Lead in Drinking Water Act, which passed in 2011, will go into full effect on Jan. 4, 2014. It may come as a surprise that the plumbing industry, through Plumbing Manufacturers Intl. (PMI), was a primary proponent of getting this law passed, in the spirit of harmonizing regulations across the U.S.
Organizations work together to prepare the industry for the low-lead deadline
At first glance, this issue of Water Quality Products might seem to have a rock ‘n’ roll theme, with phrases like “rock on” and “heavy metal” peppering the article titles — but unfortunately the issue at hand is anything but rock ‘n’ roll.
The focus of these articles is heavy metals, contaminants that lately have been making more waves than usual within the industry. Between the quickly approaching deadline for the new federal low-lead law and the recent release of California’s proposed chromium-6 limit, it is one that will continue to be a concern.
