September 2002 stormwater flow; view oriented upstream at streamgage 08329870, Bear Arroyo at Jefferson Street site.
Date Published: September 20, 2017

The system of drainage channels and natural stream channels in the Albuquerque metropolitan area is a source of concern because of potential local flooding and water-quality problems. Rapid urbanization since 1970 has increased precipitation runoff to these channels, which in many instances return flow to the Rio Grande. As an important element of the City of Albuquerque’s water-resources...

The U.S. Department of Energy has proposed a location for a new facility to store waste at the INL. In the unlikely event that waste leaks from the facility, it will be important to monitor whether the contamination reaches the aquifer and baseline information is need before the facility is built.

Because we need to know how water and contaminants may travel through the aquifer, we need...
