What's New In Aquifer Testing?

Thank You to the participants who attended the 2014 Aquifer Testing Course in Fort Collins. On behalf of the instructors and myself, you helped make this year's course one of the most enjoyable and memorable ever!

Thanks to our host, In-Situ, Inc, for sponsoring this powerful course at their headquarters in Fort Collins, Colorado.  In-Situ staff hospitality overflows with their friendly welcome and professional organization of facility tours, a fun evening reception, and a glimpse into the inner sanctum of the world's leading manufacturer of aquifer testing equipment.

2014 Aquifer Testing Course Participants

Jim Butler's and Glenn Duffield's abilites to teach and connect with people coupled with their content provide the core to this 2-day educational experience.  One of the unmentioned benefits of the course besides simply learning and enjoying the experience is gaining accessibility to both of these recognized experts.    

When the course is complete and we have all returned home, sometimes technical questions arise, right?  

The course creates familiarity with the instructors who offer their assistance to professionals beyond the classroom.  Glenn Duffield is the author of AQTESOLV and his door is open to course participants that ask for assistance with data analysis after the course is complete. Plus, In-Situ provides technical assistance of all types, all the time.

We never take course and webinar registrations for granted and we recognize our responsibility to truly help each other on all levels.  Thank you for giving us that opportunity to help you.  -Dan

Solid "H(o) Slug" .....what is it?

Pronounced:  H naught slug

The Solid H(o) Slug™ is a traditional solid slug that is designed to yield a pre-estimated initial displacement during a slug test. 

It's a new item available only through Midwest GeoSciences Group.  The H(o) Slug may ordered in either teflon or PVC.  

Calculated initial displacement is represented by "H(o)*" where H is the calculated distance of instanteous change at time zero (o) in water level created by the the slug.  "H(o)" is the measured initial displacement.  It is important to compare calculated H(o)* with measured H(o) as part of the QA/QC of the slug test for checking the reliability of test data.

The 60-sec video below shows initial displacement occurring within a two-inch diamter well using the H(o) Slug for a one-foot initial displacement.  Note how the water level changes by 1 foot after dropping the slug mimicing the initial displacement during a falling head slug test.

The H(o) Slug is available now at http://www.midwestgeo.com/ for both english and metric units:
12 in, 18 in and 24 in  --or--  30cm, 45cm, 60cm. 

Learn why slug testing with different initial displacements is very important and how normalizing the data can create appreciable data analysis efficiences using the FIELD GUIDE FOR SLUG TESTING AND DATA ANALYSIS.
