Albuquerque – Albuquerque's water utility has resumed delivery of Rio Grande water to metro area customers.
That's after tests showed the utility's treatment plant was successful at removing ash from flooded fire areas upstream.
The Albuquerque Bernalillo County Water Utility Authority had temporarily switched to using groundwater due to concern over the amount of ash in the river water.
Thunderstorms over the area burned by the Las Conchas wildfire have sent debris flows and ash into the Rio Grande.
The Water Utility Authority concluded after a Thursday test run that its water treatment plant was having no difficulty removing the small amount of ash now in the river.
The Albuquerque Journal says heavy levels of ash in the river forced the utility to switch to groundwater pumping on July 22.
