Test water quality with an Android app

While we use various purifiers to ensure the water we consume is as safe as possible, many of these solutions come at a high cost and with a lot of inconvenience. Well, John Feighery used to work for NASA, providing safe water to people in space. After the Columbia Space Shuttle accident in 2003 in which seven crew members died, he began focusing on water and sanitation issues for those on earth.

In an exclusive interview, Feighery told AlertNet, "I'd been working on supplying clean water to three or four people in space, and meanwhile there are a billion here on earth that don't have it. The world that my kids are going to grow up in has this huge problem that I felt I could work on."

Feighery realised that the need for heavy equipment, charting notes and mapping locations by hand and transporting samples in incubators to a GLVWDQW ODERUDWRUY QHHGHG WR EH VLPSOLfiHG and made less expensive. This led to the idea of using inexpensive testing equipment available online, along with mWater, which is an Android app that records the data results of water quality tests and maps them.

This Android app is available in the Google Play store and allows people to track water quality tests at any given water source over time, thus, offering instant results.
