Tracking wastewater's path to wells, groundwater

Wed, 24 Jan 2018 03:03:32 EST

We often "flush it and forget it" when it comes to waste from toilets and sinks. However, it's important to be able to track this wastewater to ensure it doesn't end up in unwanted places. A group of Canadian scientists has found an unlikely solution.

Scientists developing new, low-cost tool for detecting bacteria in food and water

Tue, 23 Jan 2018 17:09:36 EST

Food scientist Lili He and colleagues at the University of Massachusetts Amherst report that they have developed a new, rapid and low-cost method for detecting bacteria in water or a food sample. Once commercially available, it should be useful to cooks using fresh fruits and vegetables, for example, and aid workers in the field responding to natural disasters, He says.
