About Disposable Polyethylene Bailer Unweighted 1.5'' OD

A bailer in hydrogeology is a hollow tube used to retrieve groundwater samples from monitoring wells. Groundwater monitoring wells are drilled in areas where there are underground storage tanks or where there is environmental remediation occurring. The wells are typically built out of PVC casing which is slotted to allow groundwater to flow freely through the well. Bailers are tied to a piece of rope (usually made from nylon or polypropylene) or a piece of wire (composed of Teflon or stainless steel) and lowered into the water column. Once lowered, the bailer uses a simple ball check valve to seal at the bottom in order to pull up a sample of the groundwater table. Bailers can be disposable or reusable, and they are made out of polyethylene, PVC, FEP or stainless steel.
