Eco Bailers for Sampling Groundwater

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 4 classes of Eco Bailers:

  • Clear PVC – regular or heavy wall to sink faster
  • Polyethylene – regular or heavy wall to sink faster
  • Hydrocarbon Recovery
  • Double Valve – Groundwater Interval Sampler

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, including the narrow 0.5 inch (12.5 mm)and 0.7 inch (18mm), 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

All Clear PVC 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 one of the 4 types of bailers; 1) Clear PVC, 2) Polyethylene, 3) Hydrocarbon Sampling or 4) Double Valve for Interval Sampling

Make sure the EcoBailer 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.
  • Most popular are Clear PVC 1.5 inch x 3 feet long 1 Litre Eco Bailers
  • Waterra Groundwater Filters work very nicely with the Eco Bailers

Clear PVC EcoBailer - Regular and Thick Wall (Weighted)

The Clear PVC Eco Bailer for sampling groundwater is as heavy (or heavier) than conventional weighted bailers without the addition of bulky and costly weights. A better weight distribution allows the Clear PVC EcoBailer to sink straighter and the efficient valve design makes it the fastest sinking bailer available.

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

Hydrocarbon Recovery EcoBailer

Eco Bailer Hydrocarbon Recovery Bailer carried by Waterra

Captures Only Hydrocarbons

The Clear PVC Hydrocarbon Recovery Eco Bailer is designed to help you remove the LNAPL, floating hydrocarbon product, from your monitoring wells without removing water as well.

This bailer is made from the same durable, rigid PVC as the regular Clear PVC Eco Bailer and so has all the same great qualities. The Hydrocarbon Recovery Bailer uses a specially designed ball which floats in water but sinks in in hydrocarbons.

THESE BAILERS CAN NOT BE BOTTOM EMPTIED

Double Valve Eco Bailers for Interval Sampling

Eco Bailer groundwater sampling - PVC Weighted carried by Waterra

Double Valve Clear PVC Eco Bailers are used to sample a discreet groundwater interval in a well and then isolate the sample from the water column by means of an upper and lower valve system on the bailer. The sample can then be recovered to surface for evaluation.
