Recovery Analysis Strategies and Techniques

Discover and learn the most up-to-date information about
aquifer pumping test techniques from some of the most
recognized authorities in ground water.

Aquifer Pumping Tests are a key element to site characterization, water resources assessment and remediation system design. Even when you are confident of the geologic conditions, you may have difficulty designing effective aquifer tests, running field equipment or selecting the best available model to analyze the test data. Where do you turn for help with aquifer testing?

Midwest GeoSciences Group & In-Situ, Inc. can help! We have designed a powerful six-module webinar series about pumping test design, field methods and data analysis techniques.This course will highlight key steps for modernizing your aquifer testing from beginning to end.

MODULE FIVE teaches the important elements of Recovery Testing, which follows the constant rate pumping tests. Recovery test data are an integral part of the aquifer pumping test program and attendees will discover valuable insights this testing offers.

Recent advances in AQTESOLV software help professionals get more from both the constant rate pumping tests and from the measurements of recovery when pumping is stopped. Hydraulic boundaries may be better assessed with high-quality recovery data. Today tests are considered completed only when the recovery data are collected and analyzed, taking full advantage of the additional information that can be obtained by considering the recovery phase as an integral part of a pumping test.
