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.

"We have switched almost exclusively to Hydrasleeves (we also tried PDBs and pumping previously) and are saving our client a large sum of money in labor costs each and every event. Additionally we have found less errors in data collection."

"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."

" 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."

"Deployment of a Hydrasleeve is as easy  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.
I am pleased with everything about this product except one thing. I wish I was the one who developed it."
