HydraSleeve™
A
new, disposable, passive, no-purge, ground-water sampler
for all contaminants
Application:
Short
and long term monitoring
Low
yield wells
UST
applications
Discrete
interval sampling and vertical profiling.
The HydraSleeve™ “cores” a
water sample from a defined interval within the well screen, then
seals itself.
Why use the HydraSleeve?
 HydraSleeve
samplers are inexpensive, disposable, and easy to use.
A discrete,
instantaneous "core" of water is collected
from a precisely defined vertical and horizontal interval.
Samples
are collected with little or no aeration, agitation, degassing,
or displacement.
Samples
can be collected at in-situ pressure and analyzed for all parameters.
HydraSleeve
samples do not blend fluid from different vertical and/or horizontal
zones
Limitations:
Limited
sample volume.
One
shot sample method.
Other uses:
Sample
crooked or damaged wells.
Vertically
define contaminant concentrations in wells.
Collect
samples from discrete intervals in surface water bodies and tanks.

Unlike any other groundwater sampler, the HydraSleeve 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.
Applications
HydraSleeve 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 multi layered contaminant concentrations.
