No-Purge Groundwater Sampler
Unlike any other groundwater sampler, the HydraSleeve passive sampler instantaneously "cores" a whole water sample from a defined vertical and horizontal interval (usually within the well screen). HydraSleeve samples do not blend fluid from different vertical zones or pull water in from outside the well screen, but instead sample via ambient and/or diffusive flow of groundwater through the well screen.
The sample is collected without purging and with very little downwell disturbance, providing excellent control of turbidity. This minimizes the time spent on filtration of turbid samples typically collected after purging with a bailer or submersible pump.
Samples can be collected at in-situ pressure with almost no aeration or degassing. This prevents alteration due to loss of volatiles or oxidation of sensitive parameters. Samples can be analyzed for all parameters.
HydraSleeve samplers are inexpensive, disposable, and very quick and easy to use, resulting in significant savings on startup and ongoing costs when compared to other sampling equipment such as bailers or pumps.
HydraSleeve passive ground water sampler is the best available technology for sampling low yield wells. It is suitable for both short and long term groundwater monitoring, and is especially useful in narrow, constricted, or damaged wells. It can also be used to sample discrete intervals from surface water bodies and tanks.
Cost savings of HydraSleeve sampling (typically 50 to 75%) make it an extremely effective option for monitoring UST leaks, dry cleaning plants, and other small-scale point-source contaminant sites. Samples collected with the HydraSleeve correlate well to other sampling methods, and it can even be used for special challenges such as in-well vertical profiling of multilayered contaminant concentrations.
