What is Concrete Slurry & Wastewater?
Construction sites have long been identified as a large contributor to urban runoff pollution because of our negligence in not regularly performing pollution prevention practices. Materials washed into the storm drain have a direct impact on local waterways and habitat living in that environment. The most common discharge into our storm drains from concrete construction is the residue and contaminants from washing down equipment such as concrete trucks, pumps, mixers, chutes, hand tools and wheelbarrows. Saws and grinders use diamond blades to cut and grind concrete and masonry products. With water being a necessary ingredient to cool the diamond blades, the cutting and grinding process generates a mixture of superfine material or sludge – also called concrete slurry. Concrete Slurry & Wastewater is Caustic: Capable of burning, corroding and destroying living tissues. Concrete contaminated water typically has a high pH value, ranging between 11 and 12 on the pH scale. This type of high
