Water is fundamental for sustainable development. Water bodies are basic as supply sources and also serve as stormwater reservoirs for urban communities. The rainwater ends up at local water bodies after its course through roads and sidewalks, collecting suspended solids usually associated with chemical contaminants. These contaminants potentially influence the population’s health by generating toxicity to the genetic, immune, and endocrine systems. This study aims to address the effect of traffic-related pollutants in stormwater contamination in the Las Vegas Metropolitan Area (LVMA) as a starting point for identifying solutions to the problem. Roadside dust samples were collected in different locations along the LVMA using an H2O filtration vacuum. The presence of heavy metals (e.g., iron, copper, and lead) and Total Petroleum Hydrocarbon (TPHs) in these samples were analyzed using Hach methods. In each sample, different concentrations of each heavy metal and TPHs were found suggesting that the residue from the vehicles in areas around the valley will reflect levels of contaminants in roadside dust that possess the potential to enter into stormwater effluents and reach Lake Mead, the main source of drinking water for LVMA.
