Point source sampling is ideal for obtaining high quality, representative samples of groundwater 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 disposal of purged water.
The Point Source Bailer can be used to profile an open borehole or screened well, collecting samples from distinct levels or points of inflow. Sample biases due to mixing of the sample 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 lowering into the well. This prevents water from entering the sampler until the desired depth has been reached.
About of Solinst Model 429 Point Source Bailer Groundwater Samplers
The Point Source Bailer is stainless steel and has dual ball valves, top and bottom. This prevents a sample collected at a discrete depth from mixing with water from other depths during retrieval. It is a simple and cost effective device for aquifer profiling, and collecting samples from distinct levels. Purging and disposal of purge water can be avoided. The miniature 0.5″ (12.7 mm) diameter model is ideal for use in narrow tubes and direct-push devices.
