What must be done with hardened and liquid concrete waste?

• A. Can be disposed with ordinary trash.
• B. Hardened and liquid concrete waste must be removed and properly disposed.
• C. Discharged into storm sewer after solidification.
• D. Shaken into the soil as fertilizer.

Answer: (B)

Handling both hardened and liquid concrete waste requires removal from the site and proper disposal. Concrete waste can contaminate water and soil if it isn’t handled correctly, and regulations typically prohibit dumping it with ordinary trash or discharging it to the storm sewer. Liquid concrete waste, if poured or allowed to seep, can solidify and clog drainage systems and release pollutants, so it must be contained, transferred to appropriate containers, and taken to a permitted facility or recycled where allowed. Hardened concrete debris should be disposed of at a construction and demolition waste facility or recycled as aggregate rather than dumped in the trash. It should never be released into the storm sewer or spread on soil as fertilizer due to the potential to disrupt water quality and harm ecosystems.
