A few months ago we heard it through the grapevine that a new HydraSleeve study was being conducted by the United States Geological Survey and that we would we pleased with the results. Well, the report has been released and, we are very pleased with the results.
The USGS compared 3 no-purge sampling devices. Our HydraSleeve (U.S. Patent No. 6,481,300; No. 6,837,120; others pending) called a tubular grab sampler in this report, rigid porous polyethylene diffusion samplers and regenerated-cellulose membrane diffusion samplers. The report evaluates the results of these no-purge samplers for monitoring concentrations of explosive compounds in groundwater, including perchlorate, when compared to pumped samples. The results confirm that no-purge sampling can be a useful alternative to pumped sampling.
We have included links to the new study on our Independent Studies page or you can view the report through the USGS website.
This is the latest independent report to confirm that HydraSleeves provide comparable data to low-flow pumping - this time for explosive contaminants. One of the reasons we are so excited about this study is that the HydraSleeves were used alongside other no-purge samplers. According to the study, the 1-liter Hydrasleeve and 2-liter SuperSleeve provided the largest sample volume of the no-purge devices that were tested, and took the least amount of effort to assemble and install in the field.
