A spill containment and remediation system. A reel for a boom is mounted in the upper part of a weatherproof housing. The lower region of the housing is leakproof and can store recovered liquid spill. A boom or dike is mounted on the reel. The housing has an opening which is normally sealed shut by a door. The housing is configured to be mounted on the exterior of a tanker delivery truck. When a spill occurs the door is opened and the boom readily deployed through the opening. After use, the containment boom can be reeled-in and stored over the lower region of the housing.
