Use Concrete Washout Containers
Environmental and Human Health Impacts
Concrete washout water (or washwater) is a slurry containing toxic metals. It’s also caustic and corrosive, having a pH near 12. In comparison, Drano liquid drain cleaner has a pH of 13.5. Washwater must be handled with care on site due to its potential to burn human skin.
In terms of the environmental impact, washwater is harmful to the environment. If the washwater is dumped on the ground, it can run off the construction site to adjoining roads and enter roadside storm drains, which discharge to surface waters such as rivers, lakes, or estuaries. In areas where run off is not probable, the washwater can penetrate the ground, impacting the quality of soil, and eventually the water table.
The red arrow in in the photo above points to a ready mixed truck chute that’s being washed out into a roll-off bin, which is NOT watertight. Leaking washwater, shown in the foreground, will likely follow similar paths to nearby surface waters. The second photo shows how ready mixed chutes can “washout” into a specially prepared, portable washout bin resulting in no leakage.
Western Disposal Services in Albuquerque, NM has purchased 30 concrete washout containers for rent in Central New Mexico. Western Disposal is pitching in to protect the environment.
