"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."
