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.
Drone Sampling with HydraSleeve , March 17, 2020 Golder Associates tested what they call the Matrice-HydraSleeve method of sampling from pit lakes. Used standard Surface Water Adapter (SWA) with a SuperSleeve HydraSleeve mounted on a Matrice 600 drone. Successfully sampled 10 pit lakes in 4 USA states collecting 81 depth-specific samples. |

HydraSleeve testing OAS Pond, September 6, 2019 The Department of the Interior tested the HydraSleeve Drone Cone in a pond in Boise, Idaho. They repeatedly successfully sampled via drone and the new assembly. Since then, the DOI has approved the new Drone Cone assembly for surface water sampling. |

The HydraSleeve...typically produced the best results "The HydraSleeve was substantially less expensive" "The HydraSleeve was simpler to deploy and retrieve, and permits a larger volume of water to be collected."

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