In these images  you might not see a water truck however there definitely was one onsite. That truck was unable to keep up with two loaders and hundreds of  trucks a day.There must be an  understanding that the critical progress limiting task in this situation would be water trucks efforts and abilities.  

The loader operator looks healthy and ok with it,  but I wonder what the parents of children swimming in  The Perris Drop Zone Water park  think about the particulate matter. The Clean up of operations that are necessary for the production of clean water have predictable byproducts.  These removed contaminates need proper care of processing and safe removal.
