Hydraulic Capture – Map View

Takes advantage of natural groundwater flow –Draws contaminant toward the well faster than it would have arrived under natural gradient flow. –Minimizes the volume of water that needs to be pumped and treated. –Does not recover downgradient contamination. –Prevents downstream migration of contamination as long as pumping continues.

What happens if the plume is too wide?

Capture zone width can be increased by: –Pumping at a faster rate –Installation of more than one well meters Double Well Capture Zone Type Curves Flow
