Abstract
An environmental monitoring well housing and protection method. A housing is disposed over the end of an environmental monitoring well pipe and set in concrete along with the well pipe itself so that the space between the housing and the well pipe is filled with concrete below the end of the well pipe. Fins extend outwardly from the housing into the concrete to anchor the housing. The housing has an interior ledge for receiving and supporting a cover. A flexible gasket is placed on the ledge, the cover is placed on the flexible gasket, and the two are fastened down by a pair of bolts that screw into threaded bores in the ledge. The bolts have five-sided heads and a special tool is provided for installing and removing them.
The cover thickness is substantially the same as the distance from the top of the housing down to the ledge, so that where the top of the housing is mounted flush with the ground the top of the cover is also flush with the ground.
The cover includes recesses for the heads of each of the bolts, so that the resultant well head is entirely flush with the surface of the ground. The flexible gasket has an adhesive material on its underside for attachment to the ledge. Apertures in the cover through which the bolts extend are sized to receive a tip of the special tool for use in lifting the cover.
