ITRC's Pump & Treat (P&T) Optimization training aims to summarize existing information and best practices while also developing a systemic and adaptive optimization framework specifically for P&T well-network design and management. P&T systems have been one of the most commonly used methods for hydraulic containment and treatment of contaminated groundwater at sites with large groundwater plumes. This method cleans up groundwater contaminated with dissolved chemicals by pumping groundwater from wells to an above-ground treatment system that removes the contaminants. Optimization of P&T remedies is important for maintaining contaminant removal effectiveness throughout the operation lifetime and managing the system toward an exit strategy. A strategy for routine optimization of P&T remedies is key for maintaining the contaminant removal efficiency of these systems. The primary audience for this training is environmental project decision-makers, which may include federal, state, tribal, and various local agency employees; contractors to these agencies; and potentially liable parties and their engineers and consultants as well as involved stakeholders. Generally, those involved in designing, building and operating, and optimizing pump & treat systems would benefit.The goal of the training is to provide a roadmap for optimizing a P&T system and refining the remedial strategy or shifting toward another remedial approach. Pump & Treat optimization should be systematic and data-based, and the training and document aim to provide tools and direction to assist in this rigorous process.Key TakeawaysUnderstanding the P&T project lifecycle: evaluation, optimization, and transition, as well as considerations for sustainability, resiliency, and regulatory and stakeholder entities.P&T optimization should incorporate adaptive site management. P&T systems are influenced by a diverse collection of outside factors, which should be considered throughout the entire optimization process.Transition and termination should both be considered during the optimization process.Remedial objectives dictate evaluation and optimization efforts for P&T systems..Prior to attending the training class, participants are encouraged to view the associated ITRC Pump & Treat guidance document.
