The HydraSleeve “No-Purge” Groundwater Sampler

The HydraSleeve makes groundwater sampling a simple, three-step operation that is more effective than pumping or bailing, and can cut field sampling cost and your carbon footprint by 50 to 80%.

The low-cost, disposable HydraSleeve captures a "core" of water from any discrete interval in the screened portion of the well with no change in water level and minimal disturbance to the water column.

The HydraSleeve is sealed except during sample collection, then re-seals itself, assuring that a formation quality sample is recovered.

The low-profile HydraSleeve can be fabricated in various sizes to match well and sampling requirements.

The Department of Energy's Office of Environmental Management uses the HydraSleeve to sample 230 wells at their Savannah River Site.

  • EM expects to save over $2.5 million over the life of the site's groundwater sampling program.
  • Saves time over traditional purge methods of sampling.
  • Complicated equipment is unnecessary.

"The Hydrasleeve...allows remediation engineers to monitor for contaminants...without purging, a time-consuming practice of removing water that often must be disposed as hazardous or radioactive waste."

Concentration Comparison of Selected Constituents between Groundwater Samples Collected within the Missouri River Alluvial Aquifer using Purge and Pump and Grab-Sampling Methods, near the City of Independence, Missouri, 2013

This study includes agricultural nutrients sampled with the HydraSleeve as well as numerous other parameters.  The takeaway is that HydraSleeve can work to replace the current sampling method (volume purging) except for sample volume needed for duplicates samples.  The wells are all 2-inch diameter with 5-foot screen intervals, limiting sample volume available for no-purge sampling.  The laboratory required 2-liters of sample for duplicate analysis. The investigators are planning to either reduce the number of parameters analyzed or reduce the analytical volume requirements for duplicate samples during the next phase of the study.

Praise for HydraSleeve

The time and cost savings with Hydrasleeves is phenomenal. You have to remember you are eliminating the cost of purge water disposal and all the hassle that entails. The advantage in time and effort versus bailing tens of gallons from a 200 feet deep well doesn't need explaining. The fact that more and more regulatory agencies are accepting this technique is a clear indicator that this is actually a superior sampling method to the antiquated bailing method and at least as good as if not better than low flow sampling.

We have completed the project and were very happy with the HydraSleeve sampler. It was very easy to deploy and retrieve samples and the sample volume was adequate to analyze for SVOCs and Metals. The sampler cut sampling time by about 80% (about 15 minutes per sample.

The comparison of the analytical results between analytical results of our Hydrasleeve samples and low-flow samples were comparable.

HydraSleeves have helped our client save thousands! We were renting lots of equipment every quarter to pump wells that were 300’ or deeper costing time, money, and man power to collect a sample. Before, we had 3-4 people, 2 trucks, a generator, 2 pumps, and lots of wiring, tubing, and hours devoted to each well not to mention the decontamination procedures after each sample was collected. Now, we drive to a site with a 2 man crew and can grab a sample in a matter of minutes. We can get all of our wells sampled in one day as opposed to 4 or 5!
