Drilling Treatment Wells at 100N
Name: Drilling Treatment Wells at 100N
Document Date: 10/16/2009
Keywords: recovery, drilling, wells, groundwater, treatment, 100-NR-2, apatite, barrier, strontium-90
Area: 100N
Description:
Using Recovery Act funding, contractors are drilling more than 250 wells to support groundwater treatment and monitoring systems. In this photo, workers prepare to begin drilling operations for wells at the 100-NR-2 operable unit. The wells will extend the current apatite barrier by 600 feet to address strontium-90 in the 100N Area. The apatite binds to the strontium-90, locking it into place while allowing water to pass through.
