Polyethylene Eco Bailers for Sampling Groundwater

Polyethylene eco bailers for Sampling Groundwater

Waterra carries a large inventory of eco Bailers for sampling groundwater needs. All bailers are PFAS, PFOS & PFOA free.

Bailers are a very simple, inexpensive device used to collect groundwater samples from piezometers and monitoring wells. They are simply a tube with a bottom valve that is attached to a retrieving line or cord and allowed to drop into the water column to the desired depth. When the desired depth is attained, the ball in the tube seats thereby trapping the water in the tube. Recover the bailer and trapped water using the retrieving line or cord.

There are 2 types of Polyethylene eco Bailers:

  • Regular
  • Thick wall – Weighted

Bottom Emptying

These bailers are designed with a special valve and valve seat to provide more positive sealing and less clogging when removing the bailer from the well. All  bailers come with the handy Bottom Emptying Spout. It assists in collecting non-aerated samples from the valve end of the bailer, which is ideal for VOC sample collection. Note the Hydrocarbon Recovery Bailers are not bottom emptying.

Adapts to Disposable Filters

Polyethylene eco Bailers are easily adapted to the Waterra 0.45 micron Groundwater Filters for collection of samples for metals analysis directly from the bailer.

A short length of 1/4″ OD or 1/2” OD LDPE tubing along with the Bottom Emptying Spout can be used to easily connect a Waterra Groundwater Filter to the bailer. This allows the bailed sample to flow by gravity directly through the filter and into a sample container. In many cases, a 1 litre sample can be filtered in under 2 minutes using this method.

Let’s get started...

Choose The length of bailer you would like and then decide Regular versus Weighted

Make sure the eco Bailer diameter is smaller than the inner diameter of the well

Do you need Bailer Cord or Filters for your field work?

Waterra Words of Wisdom

  • Use a smooth hand over hand technique to minimize sample agitation when recovering your sample from the well
  • We don’t recommend tipping over the bailer to decant your sample from the top of the bailer as it aerates the sample and is tricky to handle the bailer. Use the Bottom Emptying Spout.
  • Waterra Groundwater Filters work very nicely with the eco Bailers

Polyethylene eco Bailer - Regular and Weighted

eco Bailer groundwater sampling - Regular and Weighted Polyethylene carried by Waterra

Regular and Weighted Polyethylene eco Bailers – Regular and Weighted -use the same design as the popular Clear PVC eco Bailers. They also feature a thicker tube wall than competing models. As a result, they are less likely to bend when handled. Bent bailers will oscillate when travelling down the well column and they will sink more slowly.
