OAR 690-240-0420
Well Protection

(1)

Every monitoring well shall be capped and protected using one of the following methods:

(a)

If the well is cased with metal and completed above the ground surface, a lockable cap with lock shall be attached to the top of the casing;

(b)

If the well is completed above the ground surface, and is not cased with metal, a metal protective casing shall be installed around the well. The protective casing shall extend at least six inches above the top of the well casing and at least two feet into the ground. A cap shall be attached to the top of the well casing and a lockable lid with lock shall be attached to the top of the protective casing; and

(c)

If the well is completed below ground surface, a lockable, watertight cap with lock shall be attached to the top of the casing. A vault or monument, designed to be watertight, level with the ground surface, shall be installed to prevent the inflow of surface water. The cover must be designed to withstand the maximum expected loadings.

(2)

All wells completed above ground shall have a minimum casing height of one foot above finished grade and shall be protected from damage by three metal posts at least three inches in diameter, set in and filled with concrete. The protective posts shall be installed in a triangular array around the casing and at least two feet from it. Each post shall extend at least three feet above and three feet below the ground surface.

(3)

If the well is to be protected by other surface protection methods, the bonded constructor shall obtain special standards from the Department as specified in OAR 690-240-0006 (Special Standards).
