Point Source Bailer: Representative Groundwater Samples Right at the Depth You Need

Capture water from a specific point in the well, reduce mixing bias, and simplify your groundwater monitoring.

Point source sampling is ideal for obtaining high-quality, representative groundwater samples from specific depths. It allows the collection of water that has just flowed into a well at the desired sampling point. This can avoid purging and the disposal of purge water.

The point source bailer can be used to profile a borehole or screened well, collecting samples from various levels or inflow points. Sample bias due to mixing with water from different levels in the well is minimized. For point source sampling, Solinst also manufactures the Model 425 Discrete Interval Sampler, which is pressurized before being lowered into the well.

This prevents water from entering the sampler until the desired depth is reached. (See Model 425 datasheet).
