Credit: 4 PDH
Subject Matter Expert: Mark Knarr, P.E., CEM, LEED AP BD+C, PMP, CCEA, GPCP
In Cost-Effective Design of Pump and Treat Systems, you'll learn ...
- How to estimate the system design mass flow for each constituent in a pump and treat (P&T) system
- Guidance on the design and selection of vertical wells, angled wells, pumps, wellheads and piping
- How to select the most appropriate technology to treat contaminants
- Advantages and disadvantages of various discharge options for P&T systems
Many methods are used to clean up pollution at Superfund and other sites. Pump and treat (P&T) is a common method for cleaning up groundwater. To remove polluted water from underground, an extraction system is built, usually consisting of one or more wells equipped with pumps. When the pumps are turned on, they pull the polluted groundwater into the wells and up to the surface. At the surface, the extracted water may undergo treatment via numerous methods (e.g. air stripping, GAC, ion exchange) to meet discharge requirements for specific contaminants. Following treatment (if necessary), the extracted water can be discharged to a surface water; reinjected into the subsurface; discharged to a municipal treatment plant; or reused in agricultural or industrial processes.
P&T systems are generally constructed and operated to accomplish one or more of the following: Containment -prevent migration of a constituent above a selected concentration to a receptor or potential receptor; Aquifer restoration - remove contaminant mass, including non-aqueous phase liquid (NAPL) if present, from an aquifer to achieve selected cleanup criteria; Meet requirements for the discharged water, and possibly discharged air, depending on the system An appropriately designed P&T system should achieve the ground water remedy goals in a cost-effective manner for the operating life of the system. Therefore, the design of the P&T system should account for the capital costs associated with system installation as well as the annual costs for operation and maintenance (O&M).
This course is intended for engineers who are involved with remediation of sites having contaminated groundwater.
