Six months ago I opened the refrigerator to pour myself a glass of water from my pour-through pitcher. As I was filling my glass, I realized I could not remember the last time I changed the carbon filter. I had been thinking about replacing the filter for a while—a really long while.
Determining when to change your activated carbon filter
Over the years, the public has become more aware of drinking water quality issues. Urban development has placed increased stress on water resources, which in turn has increased the need for cost-effective methods to treat drinking water. This is true regardless of whether the installation is at a single point of use (POU) or at the point of entry (POE) for treating all water used in the home.
Choosing the right treatment option for the water supply
In recent days, groundwater has been gaining attention. Increased hydraulic fracturing operations have caused controversy over potential methane gas contamination. Reports indicate that groundwater aquifers, especially in the drought-prone southwestern U.S., are being depleted more quickly than they can be recharged. Surveys, like the one recently released by the U.S. Geological Survey (USGS), reveal that contaminants such as arsenic are widespread in the nation’s water wells.
More than ever, sustainable surface and groundwater supplies are essential to communities across North America and around the world. The strains of industry and agriculture on groundwater are noticeable as pressures on water supplies intensify and supply patterns change. The increase in agriculture over vulnerable aquifers, climate change and hydrocarbon production are impacting water quality. Unregulated use or uncontrolled flow of groundwater can cause water quality degradation and conflict between water users.
Small drinking water systems opt for POE UV treatment
When McMaster University in Hamilton, Ontario, Canada, set about constructing its new Engineering Technology Building, it used the latest state-of-the-art technology not only to achieve U.S. Green Building Council Leadership in Energy and Environmental Design (LEED) Gold certification, but also to create a living laboratory to train students on the building systems of the future. One of the components is a rainwater harvesting system that collects, filters and disinfects rainwater for non-potable and potable use in the building.

I am sure many of you have seen the flood of recent headlines and articles posted all over newspapers, the Web and every news channel across the nation. The headlines are grim:
Getting to the bottom of a hot-button issue
When bottled water sales boomed in the mid-1990s, food service and hospitality operators and distributors learned that leasing point-of-use (POU) water vending products that offered fresh cold water and hot water-based beverages could be very profitable.
Treating Vending Water
There are two common types of water cooler vending systems: mains-fed from the tap and bottled water coolers. In any environment, it is important to know how to select the right type of filtration.
Filtration options to provide the best water
Wine producers in the northern California wine country, including Sonoma, Napa, Lake and Mendocino counties, encounter high levels of arsenic in groundwater extracted for use in wine processing and irrigation. These producers must lower arsenic levels to newer drinking water standards set by the U.S. Environmental Protection Agency (EPA) and California’s Department of Health Services. Arsenic removal is also indicated to ensure product safety and to maintain customer confidence in wine products.

What to expect and how to protect drinking water
Gas well drilling has been growing in activity over the past 10 years across the U.S.—specifically gas drilling within shale—due to the technological advancements in hydraulic fracturing and horizontal drilling, which has made it more economically feasible to produce. Hydraulic fracturing, often referred to as fracking, is a process that creates fractures within the rock formations to allow more fluids to flow to the well.
