Scientists worry that the Dragon Bravo Fire could threaten Grand Canyon National Park’s sole drinking water source at Roaring Springs.

Now they’re working with officials to monitor water quality and predict harmful flows.

Scientists with Northern Arizona University will install sensors and cameras that’ll alert them if water entering aquifers on the North Rim is carrying higher than normal amounts of ash and sediment.

It’s a quality known as turbidity.

Abe Springer is a ecohydrogeology professor at Northern Arizona University.

“Turbidity is an issue because it affects the water quality and standard treatments are to filter the water," Springer says. "[For example], as you know from a river trip, when you’re on a muddy river, its a lot harder to filter and your filters get plugged quic
