Disposable water samplers, also known as bailers, are devices used for groundwater sampling in piezometers, monitoring wells and environmental monitoring programs. They provide a practical and cost-effective solution for hydrogeological investigations, contaminated site assessments and remediation projects.
The Envirotecnics range of bailers and slow-discharge devices includes models manufactured from high-quality polyethylene (PE) and transparent PVC. Their design allows representative groundwater samples to be collected while minimizing the risk of cross-contamination between monitoring points and simplifying field operations.
Weighted models provide a faster sinking rate, reducing the time required for sample collection. Transparent PVC bailers also allow visual inspection of the sample during retrieval.
The range is completed by polyethylene (PE) slow-discharge devices specifically designed for volatile organic compound (VOC) sampling. These devices enable low-turbulence sample transfer, helping to minimize volatilization and preserve sample integrity during vial filling.
Available in a variety of capacities and diameters, Envirotecnics bailers are suitable for a wide range of piezometers, monitoring wells and environmental applications.
All bailers and slow-discharge devices in the range are manufactured using PFAS-free materials, helping to minimize the risk of contamination during environmental monitoring programs and groundwater sampling activities.

Disposable bailers are lowered into the well or piezometer using a suspension cord. Once the desired depth is reached, groundwater enters the bailer through the bottom check valve, allowing a representative sample to be collected.
Polyethylene (PE) slow-discharge devices enable controlled, low-turbulence sample transfer, helping to minimize the loss of volatile organic compounds (VOCs) during bottle and vial filling.

What is a bailer or disposable water sampler?
-
What is the difference between a bailer and a sampling pump?
Bailer Sampling Pump Lower cost Higher initial investment No power supply required Requires power supply or battery Easy to transport and deploy More complex equipment Ideal for spot sampling Ideal for low-flow sampling Quick installation More preparation required Limited flow control Precise flow-rate control Bailers are commonly used for routine environmental monitoring programs and spot groundwater sampling, while sampling pumps are generally preferred when low-flow sampling procedures are required or when greater hydrochemical representativeness of the sample is needed.
The choice between a bailer and a sampling pump depends on the sampling objectives, groundwater conditions and project requirements.
-
Which is better: a PE bailer or a transparent PVC bailer?
Neither option is universally better; the choice depends on the sampling objectives.
Polyethylene (PE) bailers are the standard choice for most groundwater sampling and environmental monitoring programs because they are lightweight, durable and cost-effective.
Transparent PVC bailers provide the additional advantage of allowing visual inspection of the sample during retrieval, making it easier to identify turbidity, sediment or separate phases.
Feature PE Bailer Transparent PVC Bailer Durability High High Cost Lower Higher Visual sample inspection No Yes Typical use Routine groundwater monitoring Sampling requiring visual inspection Weight Lightweight Lightweight Both materials are suitable for groundwater sampling. The best option depends on whether visual inspection of the sample is required during the sampling process.
-
What is a slow-discharge device used for?
Slow-discharge devices are specifically designed for volatile organic compound (VOC) sampling. They allow low-turbulence sample transfer, helping to minimize volatilization and preserve sample integrity during bottle and vial filling.
-
How do I choose the correct bailer diameter?
The bailer diameter should be selected according to the internal diameter of the monitoring well or piezometer to ensure safe deployment and retrieval.
-
Are disposable bailers suitable for groundwater sampling?
Yes. Disposable bailers are widely used for groundwater sampling in environmental monitoring programs, hydrogeological investigations, contaminated site assessments and remediation projects.
-
Are PFAS-free models available?
Yes. Please contact Envirotecnics regarding the availability of PFAS-free configurations for projects with specific environmental monitoring and sampling requirements.
-
What are the main applications of bailers?
Bailers are commonly used for groundwater sampling, environmental monitoring, hydrogeological investigations, contaminated site assessment, groundwater quality monitoring and environmental remediation projects.
They are also widely used for collecting samples from piezometers and monitoring wells during environmental investigation and long-term monitoring programs.
-
Do the samplers contain PFAS?
No. The disposable samplers and slow emptiers from Envirotecnics are made with PFAS-free materials, which helps reduce the risk of contamination during groundwater sampling and environmental monitoring programs.
- More biodegradable: All Geobailers are more biodegradable than traditional plastics. A special additive breaks down the plastic more quickly. The additive makes the plastic an attractive food source for certain soil microbes, helping the plastic to be rapidly consumed once discarded.
- Laboratory Certified: Geobailers are batch certified by the NELAC laboratory to be free of contaminants and suitable for environmental sampling.
- Manufactured under strict clean conditions: Made with FDA-approved high-density polyethylene resin. The polyethylene used contains no additives or plasticizers.
- Improved design: Geotech's "Orbit Flux" design fills 33% faster than other bailers.
- V-space for knot allows seamless attachment of the rope.
- Optional double check valve: isolates the sample, thereby sealing the bailer as it is removed from the well at specific depths.
- Pressurized disposable bailer: This disposable Geobailer conveniently allows the use of dispos-a-filters™ inline in the field, even when no pumps are available. By using a hand pneumatic pump, you can filter your samples directly from the bailer, thus saving time while maintaining sample integrity.
