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
Hydrofracturing is not a new concept—in fact, it has been utilized by the gas and oil industries in the U.S. since the 1940s. Thanks to increased media attention, however, many are led to believe that this is a new technology developed specifically for the extraction of natural gas.

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.

An overview of major certification agencies and the certification process
In light of recent issues with pharmaceuticals in drinking water and the increased need for filtering systems in the home, it may be time to consider all of your certification agency options. Certification is a qualifying process that ensures a purchased product meets current industry standards.
In this case, standards are publications that establish accepted practices, technical requirements and terminologies for products, services and systems.
