As winter melts into spring, environmental field teams gear up for one of the busiest times of the year: the spring sampling season. With snowmelt runoff, rising groundwater levels, and increased mobility in field conditions, spring is a critical window for collecting representative groundwater samples—especially in regions impacted by agricultural runoff or legacy contamination. A recent ...
Consider that before choosing this method. First, a small pair of bladders is rolled into place inside the testing area. The pipe is restrained to keep pressure safe and stable. Air is used to fill the bladder until it has an adequate seal, and then water is pumped in between the bladders to test. ...
After setting-up at a borehole, operators lowered the low-flow bladder pump to the required depth and ran the pump using the multi-parameter Flow Cell until Electrical Conductivity had stabilised. They then took samples. Then they lowered the bladder pump another 2 or 5 metres and took the next samples after the ...
If site technicians detect leaked product with an interface meter they can measure its depth and thickness, grab a sample with a bailer and extract product with a skimmer and bladder pump or product and water with a total fluids pump. While most applications vary a little or sometimes completely, there are solutions for all situations. ...

The monitor wells are outfitted with two types of dedicated pumps which are placed strategically to reduce the need for purging large volumes of water. An electric submersible pump is used to purge water from the well and a compressed-air-driven bladder pump is used to collect water quality samples. The submersible ...

The specific sampling and filtration variables investigated in this study were (1) filtration with 0.45-mm or 5.0- mm pore size filters versus no filtration, (2) sampling device, specifically, bladder pump, submersible-centrifugal pump, and bailer, and (3) sampling pump discharge rate during purging and sample collection using ...
In these studies, two groundwater sampling devices, a bailer and a bladder pump, were used to sample groundwater that was contaminated with either trichloroethylene (TCE), munitions, or pesticides. ...
Consistency in operation is critical to meet accuracy and precision goals. 2) Advantages Disadvantages of Sampling Devices A variety of sampling devices are available for low-flow (minimal drawdown) purging and sampling and include peristaltic pumps, bladder pumps, electrical submersible pumps, and gas-driven ...
The relative recoveries of volatile aromatic hydrocarbons with a peristaltic pump, a positive displacement bladder pump and an inertial lift 'Waterra Pump' were compared when sampling methane gas-charged groundwater. ...
