Open Source Tech Revolutionizes Water Pollution Testing Equipment

Press Release | Michigan Technological University | August 5, 2015

High nitrate levels in water cause the dead zones in the world’s largest deltas. Using too much nitrogen fertilizer wastes resources and leads to nitrate in runoff and water wells and an excess of nitrate in drinking water is a health hazard to infants and harmful to many animals. Current portable nitrate testers range in price and accuracy, from ballpark data at low price points to several hundred dollars for a handheld photometer. This new design is palm-sized, interfaces with a free Android app, costs less than $65 to manufacture and uses green chemistry for a safer and more accurate testing procedure. “This is a Popeye-approved reagent methodology,” Pearce jokes, adding that the enzyme used in the test kit is found in spinach and other leafy greens. “We’re replacing a toxic heavy metal with something that you eat every day in your salad.”

A third helps people inventory the moles on their skin and evaluate how they have changed over time...
