AQTESOLV Voted #1 Software In Poll

What is the best pumping test analysis software? Groundwater professionals, responding to a recent poll on LinkedIn, overwhelmingly chose AQTESOLV as their preferred software for pumping test analysis.[pdf]

Results of LinkedIn poll, "What's your preferred pumping test software?"

Here's just a sample of comments posted by participants in the pumping test software poll:

• "AQTESOLV [has] a great solution set with real flexibility."
• "AQTESOLV is not only a great solution but is user friendly and has great customer support that comes along with it."
• "AQTESOLV is the industry's standard. Glenn D[uffield] does a great job with continuing updating and improving an already superb product."
• "AQTESOLV is a fantastic tool. Easy to use, informative help documentation, and great customer support."
• "Totally agree with the other commenters [regarding AQTESOLV]. Glenn [Duffield] has built a wonderful product that is both powerful and user-friendly. Oh, and speaking of friendly, if a person has a question about the software, Glenn is very quick to provide help, either by phone or email. Great product, great customer service. What more could you want?"

Thanks to everyone who voted in the poll and for all of the kind words!

AQTESOLV Version 4.5 is Here!

I'm pleased to announce the release of AQTESOLV v4.5, the world's leading software for the analysis of pumping tests, slug tests and constant-head tests since 1989.

AQTESOLV/Pro v4.5 is the first commercially available software for aquifer test analysis to feature a new analytical solution by Tartakovsky and Neuman (2007). Unlike the familiar method by Neuman (1974) for pumping tests in unconfined aquifers, the Tartakovsky-Neuman solution incorporates effects of 3-D saturated/unsaturated flow to account for noninstantaneous drainage at the water table. I've optimized the numerical computations in AQTESOLV to maximize the speed and accuracy of this complicated solution.

Shown at right is a match of drawdown and derivative curves that I obtained with AQTESOLV's implementation of the Tartakovsky and Neuman solution for an observation well monitored during a pumping test on Cape Cod by the USGS (Moench et al. 2001). Note the response at intermediate time which shows gradual rather instantaneous drainage of water.

Also featured in AQTESOLV/Pro v4.5 is a version of the Dougherty and Babu (1984) finite-diameter well solution adapted for the analysis of step-drawdown tests. Unlike traditional methods for analyzing step tests, the Dougherty-Babu step-test solution considers the effect of wellbore storage on early-time drawdown data measured in the pumped well. It also accounts for partial penetration, wellbore skin and turbulent well loss. One of my customers has already applied this solution with excellent results!

AQTESOLV v4.5 comes with interface enhancements and a revised Help system to increase productivity. For more information or to order the software, please visit the AQTESOLV web site or contact me directly!

Two-Day Short Course in Calgary!

I'm very pleased to announce a two-day short course entitled Aquifer Testing for Improved Hydrogeologic Site Characterization Featuring AQTESOLV and the In-Situ LevelTROLL that will be held on August 16 and 17, 2007 in Calgary, Alberta, Canada.

This offering will reprise the very well-received course that we presented in Ft. Collins last year. The workshop covers both pumping tests and slug tests and combines lectures on state-of-the-art aquifer testing methods with hands-on use of AQTESOLV in the analysis of test data.

In addition to myself (Glenn Duffield, president of HydroSOLVE, Inc. and author of AQTESOLV), instructors for the course will include Jim Butler (2007 NGWA Darcy Lecturer and author of The Design, Performance, and Analysis of Slug Tests) and Chris Neville (Vice President and Senior Hydrogeologist with S.S. Papadopulos & Associates).

For more information, please visit the Midwest Geosciences Group web site. This course is offered in collaboration with Aquatic Life Ltd.

Welcome!

Welcome to my blog for AQTESOLV, the world's leading software for the analysis of aquifer tests since 1989!

From time to time, I'll be posting news, views, tips and short course announcements pertaining to AQTESOLV. With the addition of this blog to our other online resources (web site, knowledge base, users' group and comparison guide), I hope that you'll be able to find all the information you need regarding AQTESOLV.

In my first post to this blog, I'd like to take a moment to express my heartfelt appreciation to all of you who have supported AQTESOLV through the years. It's been a pleasure to work with you and I look forward to many more years of our continued partnership.

Many thanks,
Glenn M. Duffield
president of HydroSOLVE, Inc. and developer of AQTESOLV
