Tips and Tricks

We have two new accessories to introduce today. Assembled SWA

When HydraSleeves are used for the size well they are intended - for example, when using 2-inch HydraSleeves in 2-inch wells - they fill in a 1:1 ratio.  When retrieving the HydraSleeve through the water column, most of the water is forced into the filling bag because the water is constricted by the diameter of the well screen.  Therefore a 30-inch HydraSleeve will capture a core sample of water from the 30 inch area directly above where the top of the HydraSleeves sits in the well.

If you try to use a 2-inch HydraSleeve in a 4-inch well, a lot of the water can escape around the outside of the filling HydraSleeve - it's not forced in as fast as it would be when used in a 2-inch well.   Previously we have recommended oscillating the HydraSleeve several times before retrieving them so that you can be sure the sleeve filled within the intended zone.  

Now we are introducing a new top attachment that will mimic the mouth of a 4-inch bag.  This 4- to 2-inch Adapter for use with our 2-inch Super/SkinnySleeve will allow you to have the same fill rate as if you were using a 4inch bag in the 4-inch well without repeated oscillation.   The sleeve is threaded between the top reducer and locking ring - follow the instructions for the assembly of the Super/SkinnySleeve PVC Collars.

  As you can imagine, if the fill rate is slower when 2-inch diameter HydraSleeves are used in the constricted environment of a 4-inch well; the same is exponentially true for HydraSleeves being used in a tank, lake, pool or any surface water sampling.

The new SWA (Surface Water Adapter) will get the job done in a 6-inch well or larger.  For the Surface Water Adapter we added an even wider mouth to the top of the smaller adapter seen above in order to accommodate larger diameter wells, surface water and tank sampling.

  Both of these adapters require check valve activation with just one oscillation of the sleeve through the desired sampling zone.  Pull up on the line ~3 feet; allow it to drop back to the starting point; and then recover to the surface.  A HydraClamp will come in handy when removing the sleeve from the top adapter.  Place the clamp on the outside of the bag at the check valve to form a water tight seal.  Then remove the SWA or 4-2" Adapter and decant the sample into your lab's vials by following the instructions in the HydraSleeve Field Manual.

HydraSleeve SpeedBag

We are happy to announce that the US Patent Office has granted a patent on our HydraSleeve SpeedBag. 

Back in 2014 we published the following article on the (NEW) SpeedBag.  Here's the updated general information. 

     
In and out, no waiting.    
speedbag    
The HydraSleeve SpeedBag’s unique design  minimizes in-well mixing and eliminates the wait for well restabilization.  It still offers all the advantages of the standard HydraSleeve sampler.  Drop them down and pull them up. No waiting!    

How is this possible?

The SpeedBag has been streamlined to allow water to smoothly flow by the empty sampler as it is lowered in the well.  The empty 500mls SpeedBag and weight only displace about 50 mls - less than a VOA vial.

See SpeedBag Video here - or on YouTube here

Why use the SpeedBag instead of a HydraSleeve?

  • First deployment at a new site. Deploy and sample the well at the same time. 
  • Comparison studies. SpeedBag and other samples can be collected on single trip. 
  • Less turbid samples.  Eliminates sediment accumulation over time.
  • A single weight can be used for all wells if decontaminated between wells. 

HydraSleeve SpeedBag Specifications

  • No well equilibration period needed in 2” sch. 80 wells and larger.
  • There are 2 sizes of SpeedBag available now - both for 2-inch wells:  500 mls = Sched 80; 900 mls = Sched 40
  • Empty 500 mls SpeedBag displaces about 50mls when deployed.
  • SpeedBag has a tensile strength of about 15 lbs.

What's in your well?

Introducing a simple way to find out - the NEW Cordry Core Sampler. clampedcore

Collecting a continuous, sequential core sample from a long well screen in a 2-inch well is typically a difficult and potentially expensive task. Previously, long HydraSleeves and SuperSleeves that could carry out this job were heavy and unwieldly, and our recommendation was that retrieval should be accomplished with at least two people. Alternatively, discrete interval samples from long well screens could be taken by deploying multiple samples at the various intervals. To provide a simpler and less expensive option, GeoInsight has developed the Cordry Core Sampler.

The Cordry Core Sampler will collect a continuous, sequential core sample to vertically profile a water column. It is a thin sleeve that allows it to be easily deployed and retrieved with minimal strain or effort. Once retrieved, the sample in the sleeve will mirror the column of water in the well. Concentrations from different intervals are not mixed and can be isolated using special clamps applied to the outside of the sleeve.

The Cordry Core will be custom made per application, based on the well specs (2-inch diameter wells only) and customer needs.

The HydraSleeve motto is “Simple by Design”. You will see it all over our packaging and in our literature.

The HydraSleeve was invented to make groundwater sampling a simple job.

The first step in the process of simplifying your groundwater sampling program is making sure you get the correct HydraSleeves and accessories for your job.

Each job or sampling location is different; each well within those locations can be different.

Reviewing the well specs and assigning HydraSleeves to those wells might seem like a daunting task to some. It might look impossible to others. For us, it’s simple. No one knows our products better.

Let us do the work for you….let us make it simple. There are several different ways we can do this for you.

  1. We always review incoming orders to make sure they make sense. If something doesn’t look like it will work together we always bring it to your attention. That being said; you know your wells best – if you think it will work after we have discussed the situation – we will ship what you order.
  2. You can submit smaller jobs and general well information using our well template form – click here. After review and discussion of your job we will offer a quote for the wells listed on the form. The form is limited to 10 wells. Please see suggestion #3 for larger sites.
  3. This email address is being protected from spambots. You need JavaScript enabled to view it.. We will add our suggestion and notes to your documentation. From this, we can work up a quote for any size groundwater sampling program – large or small.

Here’s an example of the information needed as seen in our well template form:

We look forward to hearing from you. It’s our job to make your job…Simple, by Design!
