The New York State Department of Transportation (NYSDOT) is seeking to optimize vehicle/equipment washing practices with respect to: • Compliance with Federal and State requirements for the discharge of wastewater • Environmental and economic sustainability • Corrosion-related vehicle/equipment maintenance costs and vehicle/equipment longevity To further this goal, vehicle washing and housekeeping practices, wash water recycling systems, using rinse/wash water as a brine ingredient, and how different washing methods affect vehicle/equipment corrosion will be examined during the course of this research project.
