Title: A Systematic Approach for Evaluation of Capture Zones at Pump and Treat Systems Part 1

Abstract

A Systematic Approach for Evaluation of Capture Zones at Pump and Treat Systems presents a systematic approach for the evaluation of capture zones at pump and treat systems, and provides an overview of a recently published USEPA document on the topic (EPA 600/R-08/003, January 2008). The target audience for the course is project managers who review those analyses and/or make decisions based on these types of analyses. This course will highlight:The importance of capture zone analysis during ground water remediation, particularly for sites requiring containmentKey concepts of capture, such as "target capture zones" and "converging lines of evidence"Typical errors made in capture zone analysisIn addition, steps associated with a systematic approach for capture zone analysis will be discussed. These steps include the following:Step 1: Review site data, site conceptual model, and remedy objectivesStep 2: Define site-specific Target Capture Zone(s)Step 3: Interpret water levelsPotentiometric surface maps (horizontal) and water level difference maps (vertical)Water level pairs (gradient control points)Step 4: Perform calculations (as appropriate based on site complexity)Estimated flow rate calculationCapture zone width calculationModeling (analytical and/or numerical) to simulate water levels, in conjunction with particle tracking and/or transport modelingStep 5: Evaluate concentration trends Step 6: Interpret actual capture based on steps 1-5,more » compare to Target Capture Zone(s), and assess uncertainties and data gaps Examples will be used to demonstrate key aspects of capture zone analysis.« less
