The US Navy's Guide for Transitioning to Passive Sampling

At the following link you will find an interesting guideline published by the US Navy for transitioning from conventional to passive sampling for groundwater.

This short fact sheet gives you the details of designing a desktop reivew of the concept; establishing data quality objectives; designing and implementing a comparative study and the evaluation of methods and acceptance criteria.

Product updates - packaging and discontinued items

First we are discontinuing the smaller rolls of tether to accommodate warehouse space for other HydraSleeve items.  The 500-foot length is no longer available and the 1000-foot length is only available while supplies last.  We will continue to carry the 2000-foot rolls for those customers who like to use our calibrated tether.

Our HS-4-2L (4-inch ~2.5 liter) HydraSleeves will now be packaged in brown-lettered ziploc bags with HS-4 as the part number on the package.  Since we only have one standard 4-inch HydraSleeve available at this time, we made the decision to use this packaging.  Your packing slip will have this notation, so don't be alarmed if the packaging has changed - you will have the correct item (HS-4-2L) inside the ziploc bag.

hs 4

Custom size 4-inch HydraSleeves are still available as well.  They would be packaged in black-lettered ziplocs with no part number listed on the package.

15 Minutes Could Teach You 15 Years of HydraSleeve Experience

2001hydrasleeve From our very first version of the HydraSleeve, back in 2001, until this very day we continue to make groundwater sampling a simple task for you.  The HydraSleeve has gone through some changes as you can see in this photo; all for improving simplicity.  We have also learned some very interesting things along the way.

In this relatively short video you will find some very helpful tips which highlight the top 7 things that every HydraSleeve user will want to understand.  Here's a brief description and location of the topics covered:

1.  Sample Volume (minutes 1-5:12)

>Learn how to negotiate smaller sample volumes with your lab

>Learn the limitations of sample volume for no-purge sampling in specific well diameters

2.  Simplicity (minutes 5:13-6:15)

 

3.  Continuous Pull Fill Rate (minutes 6:16 - 7:36)

lessons-learned

>Learn why HydraSleeves should be sized to fit the well

>Learn what to do if you must use a smaller HydraSleeve in a larger diameter well.

4.  Oscillating the HydraSleeve During Recovery (minutes 7:37 - 10:39)

>Learn why this may be the preferred method of recovery.

5.  Discard the Water off the Top of the Check Valve (minutes 10:40 - 11:22)

>Learn how and why this is the first and most important step in decanting your sample into lab vials

6.  Single Pull Retrieval = Core Sample (minutes 11:23 - 13:00)

>See what happens when you do a single pull recovery

>Learn the best location to puncture the bag for various contaminants

7.  The HydraSleeve displaces minimal amount of water during installation (minutes 13:01 - end)

>Learn about the new SpeedBag

>See the reasons why in/out recovery may be the best for many locations and sampling events.

The most important thing to learn from all of this is:  If you have any questions or are having any problems with your HydraSleeve experience, PLEASE CONTACT US. 

Having worked with HydraSleeves for almost 2 decades and with 10's of 1000's of sleeves sold every year, we ARE the experts and we CAN likely solve your problem.  Most of the time it's just a matter of using the right HydraSleeve and accessories for the job at hand.  We are here to help in every step of the HydraSleeve sampling process.  From choosing the right equipment; to operating instructions and unusual circumstances and set ups; we can help!

As seen and explained in item #3 above:  Like a screwdriver, the HydraSleeve is a simple tool.  However just like trying to use a phillips screwdriver on a flat-head screw; not having the proper tool for the job can make it impossible to efficiently complete the job.

Interesting New Video - See the HydraSleeve Check Valve Working

Last year we created a mechanism that provides visual proof that the HydraSleeve Check Valve closes when the HydraSleeve is full and remains closed as it travels through the water in a 2-inch, schedule 40 tube (faux well).  We call it the HydraSleeve Test Chamber.

Earlier attempts at testing and demonstrating how the check valve works had to be limited to a standing water column of no more than 15 feet for logistical reasons.   Here the water flowing past the stationary HydraSleeve can represent 100's of feet of stagnant water.  Picture a wind tunnel for HydraSleeves.

 This test chamber video answers questions about the HydraSleeve check valve working when the sleeve is used in wells where large amounts of stagnant water lies above the screen zone.  As seen in the video the HydraSleeve check valve closes when the bag is full and it remains closed while it is recovered through the well casing.
