"I chose AQTESOLV for its ease of use."
David Preston, P.E., Peachtree Environmental

"I use AQTESOLV in my Hydrology and Water Resources 603 graduate class on well hydraulics and pumping test analysis."
Dr. Shlomo P. Neuman, University of Arizona

"AQTESOLV is a powerful software for aquifer test data analysis."
Dr. Vedat Batu, URS

Expect flexible tools for importing data logger files.

AQTESOLV was the first software to introduce an Import Wizard for data logger files way back in 1997. AQTESOLV presently imports data from a variety of data loggers. Expect this feature in a package for aquifer test analysis.

• AQTESOLV provides two easy methods for you to work with data logger files:
  -- import files with a versatile Import Wizard
  -- copy and paste data from spreadsheets
• AQTESOLV lets you import date/time formats.
• AQTESOLV includes handy math functions and filters to help you manipulate the data.

"The wizards are a great addition!"
Rezie Jan, URS Greiner Woodward Clyde

Select a package with superior diagnostic methods.

Diagnostic methods are an essential tool for aquifer test analysis. These tools can help you select an appropriate solution for your test. Choose the software package with the most advanced diagnostic tools.

• AQTESOLV is the only package with diagnostic flow plots for pumping test analysis: radial, linear, bilinear and spherical flow plots.
• AQTESOLV was the first package to include derivative plots in 1997. Only AQTESOLV provides you with the flexibility and power of four different methods for computing derivatives.
• AQTESOLV is the only package with an interactive slope checking tool to help you diagnose specific flow conditions.

"AQTESOLV is the 'industry standard' for the interpretation of aquifer tests."
Dr. Joe Donovan, West Virginia University

Get a software package with the most comprehensive set of solution methods.

Your ability to perform a complete and thorough analysis of an aquifer test depends on your ability to access appropriate solution methods. In this critical area, AQTESOLV is the clear leader while competing aquifer test software packages fall short.

• AQTESOLV has the most comprehensive suite of solutions for the analysis of pumping tests, single-well tests, recovery tests, variable-rate tests, step-drawdown tests, slug tests and constant-head tests.
• Only AQTESOLV provides advanced pumping test solutions for conditions such as leaky confined two-aquifer systems, wedge-shaped aquifers, nonuniform aquifers, water-table aquitards, single fractures, horizontal wells, interceptor trenches, step-drawdown tests in leaky aquifers, bounded aquifers including strip aquifers and the generalized radial flow model.
• Only AQTESOLV has advanced features for slug tests including underdamped (oscillatory) tests in partially penetrating wells, wells screened across the water table using the Dagan (1978) method, tests in fractured aquifers and analysis by deconvolution.
• Only AQTESOLV has constant-head test solutions for confined, leaky and fractured aquifers including recovery.

"I cannot imagine that I ever tried to analyze aquifer tests with manually plotted data curves using a light table. What a tremendous service you have provided with this software. Thank you."
Jim Borchers, USGS

Choose software with state-of-the-art curve matching tools.

You should expect a software package for aquifer test analysis to provide you with state-of-the-art methods for visual and automatic curve matching. Since its first release, AQTESOLV has combined these two fitting techniques.

• Only AQTESOLV provides you with three different methods for curve matching: visual, automatic and parameter tweaking.
• AQTESOLV is the only package to offer active type curves, a powerful interface feature that makes visual curve-matching analysis of variable-rate pumping tests and underdamped slug tests a snap!
• Only AQTESOLV adds the power of singular-value decomposition to enhance automatic curve matching applied to complex problems.

"The families of curves are terrific and do everything I could possibly ask. Absolutely super!"
William Hotchkiss, Ph.D., NRCE, Inc.

Look for a software package offering prediction and test design capabilities.

Predictive capabilities are invaluable for designing an aquifer test in preparation for field activities. Prediction also lets you forecast the extent of future drawdown for one or more pumping wells.

• Only AQTESOLV allows you to perform test design and prediction for pumping tests, slug tests and constant-head tests.
• Only AQTESOLV allows you to predict transient groundwater mounding for rectangular and circular recharge areas.

"I have been using AQTESOLV since 1989. It has been a great educational tool and I highly recommend it to all groundwater professionals."
Prof. Al Woodbury, University of Manitoba

Select a package with comprehensive output options for not only curve matching but statistical analysis as well.

Output should include a complete set of plots and reports to summarize the results of your analysis.

• Only AQTESOLV includes plots and reports for analyzing statistical results of curve matching.
• AQTESOLV provides comprehensive control over fonts, line styles and widths, colors and other formatting elements.
• Copy and paste plots from AQTESOLV into other applications such as Word or Powerpoint.
• AQTESOLV seamlessly links to Surfer, a versatile package for 2-D and 3-D contouring.
• Only AQTESOLV supports batch printing, a handy feature that allows you to apply consistent formatting to a group of tests.

"I really like the automatic gridding link to Surfer!"
David Dahlstrom, Barr Engineering
