How to Manage and Dispose of Concrete Cutting Slurry Safely on Job Sites

Direct Answer: Concrete cutting wet slurry is a high-pH alkaline waste mixture containing suspended respirable silica dust particles. To manage slurry safely and legally under EPA clean water rules, collect wet slurry at the cut line using a wet vacuum or slurry containment dike. Slurry must never be washed into storm drains or soil. Store slurry in containment drums, use chemical flocculants to separate water from solids, neutralize pH to 6.5–8.5, and dispose of dried filter cake as non-hazardous solid waste.
