The Power of Borehole Flow Meters

Test your bedrock conceptual site model using borehole flow meters.

-Confirm or refine stratigraphy
-Identify fractures that give (or take) water in the borehole
-Measure the flow rate between fractures
-Target meaningful fractures for monitoring

Webinar:  BOREHOLE FLOW METERS for Assessing Bedrock Stratrigraphy and Fracture Hydraulics.
Date:  October 4, 2018 @ 1pm (90 min)

Congratulations to the participants of
Managing the Complexity and Uncertainty of Soil Sequences, Part 2, Field Techniques!  

I realize the course is difficult.  No doubt that the field process for taking the mystery out of the subsurface requires a thoughtful deliberation of soil beyond simply describing it.

Luckily, we are all in this profession together...and with the teaching leadership of Martin Helmke, Tim Kemmis, David Hart, and Katie Aguliar we found ourselves empowered with a refined process to avoid common mistakes, be better prepared for the field, think on our feet, and make pertinent observations that result in soil boring logs that are both accurate and correct.

Not to mention boring logs that truly take the mystery out of the subsurface!

Thank you to all participants -- you made the course special, and meaningful.   Thanks to all for sharing your experiences, tips, and insight!   We truly appreciate getting to know you (or knowing you better building from past courses) during the course.

Take what you learned and teach it to your colleagues.  Field techniques require special mentoring and you are capable of doing it now.   

Special thanks to Parratt-Wolffe, Inc and Cascade Drilling for providing the deep continous soil cores, and the wells for West Chester University!  Wow!  Not only were the soil cores in excellent condition with great recovery for the course, the drilling staff were excellent teachers too.

Thank you BIG TIME to Eileen, Susan and Mary Beth at West Chester University for your professionalism and great facilitation with access and continuing education administration!  You do indeed rock!

Ask yourself these questions before your next aquifer test

Aquifer testing is complex.  Procedures are conceptually simple but the devil is in the details.  Any small problem can waste enormous time and budget.  Without proper training, most staff are unable to troubleshoot field and analysis questions.

Despite understanding the importance of aquifer testing, many hydrogeologists and site managers lack adequate training in test design, execution and data analysis needed to produce reliable, meaningful results.

Test your pumping test preparedness by answering these basic questions:

1. Design Objectives
Does the design meet the objective of the aquifer test?
What information can I expect from the test?
What are some ways to improve efficiency?
What are the risks and benefits associated with different test designs?
2. Construction
How many wells are needed?
How should wells be constructed?
Where do I place observation wells?
3. Field Equipment and Software
How do I select the right equipment and software for reliable results?
How do I recognize a problem?
Can I troubleshoot problems if they arise?
4. Subsurface Variability
What happens in extreme conditions of high and low hydraulic conductivity formations?
What tools and techniques can I use to obtain reliable data?
5. Analysis Strategies
Which strategies are appropriate?
How can I be sure my analysis is correct?

Get answers to these questions and more during our upcoming course: Aquifer Testing for Improved Hydrogeologic Site Characterization: Featuring In-Situ Level TROLL and AQTESOLV on October 16-17, 2018 in Fort Collins, Colorado.

Midwest GeoSciences Group and In-Situ, Inc. have partnered on this popular aquifer testing course for over 10 years and it’s become the go-to training experience for aquifer testing.

Date and Time: October 16 - 17, 2018 (8:00 am - 5:00 pm)
Location: In-Situ Headquarters in Fort Collins, Colorado
Instructors: Jim Butler, PhD, Research Scientist for the Kansas Geological Survey; Glenn M. Duffield, Founder and President of HydroSOLVE, Inc.

The instructors have created a step-wise experience to learn both the basics and advances in aquifer testing. Register today for the course and begin your next expertise in aquifer testing.
