How to Plug and Cap Monitoring Wells
Use Well Plugs
How to Plug and Cap Monitoring Wells is a key element of any groundwater monitoring program. Monitoring wells should always be plugged / capped in order to prevent foreign material from contaminating the well. Blind end caps are available at pipe suppliers and some hardware stores but Waterra carries EcoPlug and Torquer Well Plugs are purpose built and more secure.
Waterra carries Well Plugs that are available in Vented and Non-vented configurations.

- Plastic and rubber sleeve are non-corrosive
- Relatively inexpensive
- Choose a 1, 2 or 4 inch EcoPlug to match your well diameter or
- Choose a 1.5, 3 or 6 inch Torquer well plug
- Insert the Well Plug into the top of the monitoring well
- Push the Well Plug down into monitoring well so that the top plate rests on the lip of the well pipe
