Waterra eco Bailers

WaterWater Sampling

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.

Overview

There are 4 classes of eco Bailers:

Clear PVC – regular or heavy wall to sink faster
Polyethylene – regular or weighted 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.
