I have been able to use Hydrasleeves for the past year doing various well samples in a couple of different locations. The simplicity of the design really appeals to me. It saves me from having to haul and use lots of equipment for slow flow purging, or bladder pumping. I also have fun deploying and retrieving hydrasleeves (except for deep wells) and taking the sample. It is a very creative product that even allows the users to become creative. I am a fan and as long as I can I plan on using a hydrasleeve to do wells sampling. I also got to visit the hydrasleeve headquarters in New Mexico from taking an environmental sampling course. I was very impressed with the presentation of how the hydrasleeve works in a clear plastic pseudo-well. As stated before simple by design but very effective of getting a good water sample.

DBS&A field sampler completing first deployment of new HydraSleeve SkinnySleeves at a work site in New Mexico.
Use of the new HydraSleeve SkinnySleeves has reduced DBS&A's field sampling costs by over 50% than traditional bailing and low flow techniques previously used to sample the groundwater at this site.
DBS&A field sampler uses the new HydraSleeve SkinnySleeve to retrieve a groundwater sample captured from middle of screened water column in a 2-inch schedule 80 well.

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! Posted with
 the permission ofLindsay Daugherty Hatch Mott MacDonald Waynesburg, PA 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. Posted with the permission ofBob Onderko

Although there is no "official" regulatory guidance relating to the use of HydraSleeve samplers in Florida, I can attest to the fact that our FDEP project manager has given us the green light to use them (on a test basis, initially) for ground water quality monitoring (chloride, sulfate and TDS) at a mine site. Results from our first round of HydraSleeve sampling compared quite favorably with those obtained through five rounds of traditional well purging and sampling techniques, and by installing a second set of samplers in the wells after retrieval of the first units, we expect that our time onsite during future rounds of quarterly sampling will be reduced from two long days to approximately six hours. When compared to the costs and logistics associated with traditional sampling techniques, HydraSleeve sampling offers a fast, simple, safe, cost-effective and environmentally friendly alternative that should be proposed and (hopefully) implemented whenever possible. We are definitely looking forward to utilizing and promoting the use of HydraSleeves on future projects here in the Sunshine State!

I have used the hydrasleeves several times on one particular project in Massachusetts over the past few years. Before moving to the sleeves we conducted a test to compare the results with standard low-flow procedures and they were right on target. They have been a big time and money saver without sacrificing data quality at that particular site. Posted with permission of

"We have used the Hydrasleeve samplers in a trial study at the Stringfellow site, and are discussing with stakeholders re: using them for future sampling events. Our 7/30/09 report has been uploaded at our Envirostor site: http://www.envirostor.dtsc.ca.gov/public/final_documents2.asp?global_id=33490001&doc_id=6022324 ." Posted with permission of

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."

"The HydraSleeve was an economical and easy way to collect discrete samples from multiple fracture zones within a borehole. Not only is the HydraSleeve far easier to deploy than downhole packers and pumps, but using the one-time-use (disposable) HydraSleeve minimizes the potential for cross-contamination between discrete samples."

as tying my shoes. Retrieval of a Hydrasleeve is even easier because the hard part of tying the knot was taken care of during deployment. The pure simplicity is beautiful. It screams common sense when you look at the big picture. A Hydrasleeve in a screened section of a well can capture water that is the same as the surrounding aquifer. Low flow sampling will always have some influence on the sample because inserting the pump into the well disturbs stagnant water in upper portions of the well, or at the least by creating a hydraulic gradient through the well screen that is greater than normal groundwater flow. Hydrasleeves are quick and clean. No lugging loads of low-flow equipment all over the place and no need for a vehicle big enough to accommodate all that low flow equipment. There will always be a place in this world for low flow sampling however, I believe the Hydrasleeve no purge samplers are the future and should be because they are twice as fast as low-flow, less expensive, dependable, and as easy to use as tying your shoes.Don't Take Our Word For It!
In study after study the HydraSleeve (U.S. Patent No. 6,481,300; No. 6,837,120; No. 9,726,013; others pending) outperforms other methods of sampling technology. The cases below are truly Independent studies. We had no input whatsoever in administering or financing any of the results you see below.

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. |
