Groundwater extraction and treatment (aka Pump & Treat or P&T) is not a new remediation technology and is widely used for the cleanup of contaminated sites. Remedies utilizing P&T need to be evaluated, optimized and adapted to changing site conditions throughout their life cycle - not just at the startup of these systems - to improve the effectiveness and efficiency of the remedy, maintain or improve receptor protection, ensure adequate maintenance, reduce cost and liability, reduce the environmental footprint, and improve resiliency to environmental changes.

ITRC's new Pump & Treat Optimization Guidance provides an overview of adaptive management as a key to optimization and presents:

• A technical framework for conducting optimization efforts at P&T sites
• Interactive checklists for detailed evaluation and optimization guidance
• Supporting case studies detailing successful project implementation
• A process for transitioning from P&T to another more effective technology in combination with P&T
• Guidance for termination of non-effective P&T operations
