Claim 0:
1. A radon mitigation system for mitigating radon about a living space comprising:
a sump pump system having a sump pump positioned within a sump pump well pit, a pump discharge conduit, a rigid cover affixed over an upper opening of the sump pump well pit, and a radon ventilation vent in fluid communication between the sump pump well pit and an exterior environment;
a planar, pliable sealing member forming a flexible seal for covering the upper opening, said sealing member being formed of a non-gas diffusive or selectively gas diffusive membrane select from a group consisting of: elastomeric rubber; butyl rubber; EPDM, vinyl rubber; NBR; SBR; and silicone rubber;
a first sealing element that forms a continuous adhesive seal about an outer periphery of said sealing member and encompassing said sump pump well pit;
at least one access orifice formed by said sealing member, said access orifice adapted to allow for the passage of a n egressing structure;
and a second sealing element applied or affixed in a manner to provide an air-tight seal between the membrane at each access orifice and a surface of any egressing structure.
