Hydraulic containment

Hydraulic containment is an environmental remediation technique used to manage and control the movement of contaminated groundwater. The primary goal is to prevent the spread of pollutants, such as chemicals or heavy metals, from a contaminated site into surrounding areas, particularly drinking water sources. Here’s how hydraulic containment typically works: 1. **Pumping and Extraction**: Wells are installed to pump out contaminated groundwater. This extraction creates a hydraulic gradient that essentially lowers the groundwater level in the contaminated area.
