One million gallons of mine waste water have been accidentally released into a river in Colorado. Researchers in Canada have developed a device that rides on the back of a fish and measures water quality. Flooding in Myanmar has the president urging residents to evacuate.

“Upon suspending work last year, the EPA backfilled the portal to the mine. On (Wednesday), while the EPA was removing the backfill from the portal to the Gold King Mine to continue its investigation this year, the plug blew out releasing contaminated water behind the backfill.” — Nancy Argo, attorney from Durango, Colorado, on 1 million gallons of mine waste water released into the Animas River.

A device that can be attached to the back of a fish and measures dissolved oxygen concentrations in water has been developed at the International Institute for Sustainable Development’s Experimental Lakes Area in Canada. Dissolved oxygen is important for the survival of many fish, and is often threatened by excess nutrients. It is also a difficult water quality parameter to measure. The new device gives scientists the ability to continually monitor changes in dissolved oxygen. International Institute for Sustainable Development
