Explanation

A dry well is an excavated underground structure designed to receive stormwater or drainage by percolation. In Idaho, older commercial and industrial properties may have dry wells that received hazardous wastes — oil, solvents, or industrial chemicals. These can contaminate groundwater and must be disclosed and evaluated. EPA has regulated dry wells that receive hazardous waste.
