“More ambitiously, however, the Water Authority in 2007 initiated a pilot program for aquifer storage and recovery, in which a small amount of San Juan-Chama water was released into the Bear Canyon arroyo and tracked to see if it reached the aquifer. Results were positive, and the Water Authority is moving forward with plans to recharge the aquifer on a larger scale.
We will be using direct injection as well as infiltration to get the water into the aquifer. We hope to put up to 40,000 acre-feet back into the aquifer in the first couple of years. After that, we will continue to add purified San Juan-Chama water to the aquifer primarily during winter months when demand is low.“
Speaking of Albuquerque, this just-published paper shows how measuring the change in acceleration due to gravity can be used to map aquifer storage change. Importation of San Juan River water has made a big difference.
Microgravity surveying is great for this and other geo applications. I know of many geothermal fields mapped the same way to monitor fluid level and steam migration.
Good stuff!
