Abstract

A well head for landfills or other sites at which waste has been disposed provides an enlarged chamber at the top of a well pipe holding hose and cable terminations on the walls of the chamber positioned out of the access path of the well pipe. A cover unattached to the hoses and cables can be removed for access without interference from the terminations. An extraction port in the cover defines a clear channel into the well pipe for sampling and monitoring equipment.
