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. 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 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.

A method for housing and protecting an environmental monitoring well having a well pipe disposed in a well bore with an upper end extending toward the surface of the ground, comprising: (a) placing an enclosure in said well bore around said upper end of said well pipe, said enclosure being of unitary construction and having an upper opening, a lower opening and an inwardly-protruding ledge between said upper opening and said lower opening; (b) placing sealing means in said well bore between the outer surface of said well pipe and the inner surface of said enclosure, said sealing means being a composition distinct from said well pipe and said enclosure and having a characteristic that allows it to flow into the space between the outer surface of said well pipe and the inner surface of said enclosure and assume a stable condition so as to seal off the space therebetween; (c) placing on said ledge a flexible gasket having a shape substantially identical to the shape of the surface of said ledge; (d) placing on said gasket within said enclosure a cover having an upper surface and a peripheral shape substantially identical to the shape of the interior of said enclosure, and (e) attaching said cover to said enclosure so that said upper opening of said enclosure and said upper surface of said cover are substantially flush with the surface of the ground.
