The Problem with Intermittent Water Delivery in Developing Countries

It’s great to have water piped into your home, but what happens when the flow of water is intermittent?   It is not uncommon for communities in developing countries to supply water for only a few hours or less every other day, due to an inadequate water supply and/or to save on the electrical costs of...

Do Point-of-Use Water Quality Interventions Work?

In many regions of the developing world, good drinking water quality is far from a “given.” The fact is that water contaminated with fecal matter causes widespread diarrheal illness and death, disproportionally affecting children under the age of five.  Recently, a group of researchers from The Cochrane Collaboration assessed several water treatment interventions taken at the household point of use for their effectiveness in improving water quality and preventing diarrhea....

Substances that Cause Tap Water Taste, Odor and Appearance

A drink of tap water is a complex sensory experience that reflects a wide range of factors, including: the natural environment of the source water, including whether the source water hails from above (lake or river) or below (ground water) the Earth’s surface; water treatment processes; the household plumbing system; and the consumer’s sensitivity to taste and odor. This week we examine some of the common substances in water and the scenarios that may impart a color, taste or odor to tap water.... Read More »

Tap Water Taste, Odor and Appearance: Why They Matter

We instinctively use our senses to evaluate tap water. The best rated water looks crystal-clear, and tastes and smells refreshing. Appearance, taste and odor are not necessarily indicative of actual water quality, however, because water contaminants may be clear, tasteless and odorless. Case in point: the small Canadian city of Chilliwack, British Columbia.... Read More »
