Ethics. Integrity, Behavior. 2020 Ethics Webinar Series

Going to work is stressful enough because of workload. But if someone at your job is harassing you and making it hard to focus on your work, it inherently has direct and indirect costs to you, them, your employer, and even our community.

We all need guidance sometimes. Bullying, harassment, and discrimination are sensitive subjects for everyone, but they are extremely important in every sense.

Regardless if you just started working or if you're a veteran department manager.  The RIGHT ethics training is a critical ingredient to help boost you and your colleagues into a high-performance team.

Don't just register for this webinar for the ethics credit,
but register for the priceless insight that can change your life.

Don't put dirt in your mouth.

Do you recall any geology field trips when a university geology professor might put dirt in their mouth in order to estimate the "grit" percentage of fine-grained sediments?  They might explain how SILT would feel gritty between their teeth and how they could estimate it's presence, and percentage.

Professors who command the highest level of respect and reverence could be seen "biting down" on bits of dust, dirt, and mud....and then declaring the precise particle size of the sample.  That seems like an amazing feat and today in 2020 it calls into question how they "calibrated" their skills.  LOL.

Today, there's good reason not to put dirt in their (our) mouth to estimate particle size:

  1. Potential chemicals or contaminants in the soil can harm us.
  2. There's no published standard for the "Grit Between the Teeth" analysis.
  3. Reproducible test procedures seem unlikely.

Here is some Edible Sand!  There's a decent chance it would get a good "grade".  (that's a particle size analysis pun).

There are more exceptions too.  If you Google-Search "edible silt" or "Loess Cookies", you will find some interesting results about a perspective on improving health by eating dirt.  (I still don't recommend putting dirt in your mouth, unless directed by your personal physician).

Second Edition Has Arrived: The Design, Performance, and Analysis of Slug Tests

The Design, Performance, and Analysis of Slug Tests, Second Edition explains virtually all there is to know regarding the design, performance, and analysis of the most common well test for determining hydraulic conductivity: Slug Testing

The first edition became the standard reference for all aspects of slug tests. It has positively changed project outcomes and helped professionals become responsible stewards of our precious water resources by promoting best practices.

The Second Edition contains updated information and expands the focus with new developments where slug testing is applied in applications related to contaminant assessment.

New Features:
  • Presents the eight key steps for conducting reliable slug tests.
  • Describes new methods for the analysis of tests in unconfined aquifers and in highly permeable settings.
  • Expands topical coverage of LNAPL baildown tests and slug tests in small diameter wells.
  • Includes numerous flow charts that illustrate easy-to-use strategies for selection of analysis methods, and field examples demonstrate how each method should be used to get the most out of test data.
  • Contains new straightforward practical guidelines that summarize the major points of each chapter.

Written for practicing groundwater consultants and engineers, The Design, Performance, and Analysis of Slug Tests, Second Edition enables readers to achieve more reliable information from slug tests and widen the application of this common field method.

Congratulations to the participants of the 2019 Aquifer Testing Course

Congratulations to the participants of the 2019 Aquifer Testing Course in Fort Collins!  It was a pleasure to see you at the course and an honor to serve you.

On behalf of the instructors and myself, we are grateful to you for sharing your experiences, asking questions, and shining a light on challenges we all face during aquifer testing.    Our job isn't easy and we're all in this together.   I applaud you for taking the time to "sharpen the blade of technical excellence" so you can tackle that next project with mastery, fearless integrity, and confidence.

Field and Analysis Component will Include Pneumatic Slug Testing during the 2019 Aquifer Testing Course at In-Situ, Inc.

We will be conducting slug tests using the Pneumatic Hi-K Slug Assembly on October 17, 2019 during the aquifer testing course at In-Situ, Inc.  For the first time ever, we will be adding a field and analysis component to the aquifer testing course with the additional of the four newly installed wells at In-Situ, Inc.  The wells were installed for the purpose of teaching during this course.
Participants will see and practice slug testing in the new wells using the SOLID H(o) SLUGs for obtaining different expected initial displacements.    Then participants will practice transferring the test data from the transducer into AQTESOLV followed by choosing the appropriate analysis strategy and analyzing the data.

We will introduce the "BIG SLUG" during the course too.  The "BIG SLUG" is designed and built specifically for conducting slug tests in 4-inch diameter wells with known initial displacements (H(o)).

One of the most powerful elements of field practice is troubleshooting.  Everyone can appreciate the mastery of "thinking on your feet" to recognize questionable conditions, assess the problem, and then find the solution.   This course is designed to allow participants to "think on their feet" and talk-through field observations while recognizing and solving any questionable conditions that may normally arise during field and analysis steps.  How priceless is this skill?

Principles of Ground Water Dewatering: The Webinar

Even when we have a decent understanding of the geology, ground water can lead to excavation instability, project delays, and ultimately increased project costs for both the General Contractor and the Owner.

Controlling ground water is a critical factor for construction and can be unexpectedly challenging when water volumes become greater than anticipated at a project site.

Dewatering Pumps

Dewatering demands special consideration of both the construction techniques and hydrogeology like no other engineering task.

There are a multitude of strategies for approaching projects in different hydrogeologic conditions and there are seemingly endless troubleshooting techniques when groundwater becomes that "unexpected problem".

Project scale can seem daunting too.   Surface water management requires the same attention to planning as pumping ground water for some sites.  Geologic conditions, permitting, logistics, access constraint and even security are critical considerations at some sites....

,,,,,,and simply asking the right question
during the pre-planning phase can make - or break - project budget.

Some common and some unique dewatering techniques from this 35 acre excavation will be presented as case studies during the webinar. 
Midwest GeoSciences Group is tackling these tough questions about dewatering.   Join us for this 90-min comprehensive webinar about not only how to evaluate a project site, but also share strategies for determining potential flow that can be expected from an excavation, how to troubleshoot some sites when excessive water is discovered, and some unique tips about how to manage surface water for a successful dewatering program.  More Here

Bronson Gerken, PG, Technical Director of the Dewatering Design Department at Griffin Dewatering is among the most qualified to teach this important subject.   Griffin Dewatering is one of the largest dewatering companies in the world and has performed over 20,000 dewatering projects.  Griffin Dewatering has allowed Bronson to build, test, and refine many dewatering systems and improvements. He is going to share his knowledge during this purposeful webinar.

Horizontal Well Hydraulics - The Webinar Series

Horizontal well hydraulics is a science like no other.

Conventional well hydraulics are based on vertical wells, and why wouldn't it be?  After all, the analytical solutions established for well hydraulics were derived when drill rigs were drilling vertically downward!

Today, drilling is phenomenal.  Drilling technologies are essentially limitless in terms of direction, depth, multiple wells in a single borehole entry point, minimal footprint, etc. 

after Bakker et al. 2005, Groundwater
But predicting well production rates of a horizontal well is unlike calculating yield in a vertical well. The analytic solutions for horizontal wells are limited, while three-dimensional numeric models are cumbersome in view of the high degree of grid resolution required near the horizontal well (or laterals of a radial collector well).

If that isn't daunting enough, constraints for horizontal well production occur in lots of ways.  It's not just geologic conditions that can wreak havoc for uncertain production rates, but other factors too cause constraints.  It's better to be prepared with informed planning in contrast to troubleshooting a poorly producing well.

Midwest GeoSciences Group is tackling this challenge.   We are taking a big first step to unraveling the complexities of horizontal well hydraulics by announcing a two-part webinar series dedicated to this special topic:

West Chester University Rocks!

Three days of ADVANCED AQUIFER TESTING TECHNIQUES flew by with lectures from Jim Butler, Glenn Duffield, Martin Helmke and Shlomo P. Neuman.   The educational journey we take during the course is unique and engaging.   Don't take my word for it, but take the scoring of the feedback forms:  PERFECT FIVE STARS score for "Overall Course Quality".
We do this to help people.   Midwest GeoSciences Group is motivated by serving professionals with hopes our collaboration achieves not only a mastery in technical work - but becoming the best people we can all be.

As environmental and engineering professionals, our work is important and it demands fearless integrity as much as it does sound technical decision making.
The course participants rose to the occasion.  It's humbling to witness the enthusiasm and positive energy surface during any course, but this advanced aquifer testing course was especially great with so many people who already had a deep mastery of aquifer testing....and those who quickly learned the basics and moved into the expert level. Congratulations to all the participants.  We tip our hat to you!
