Mapped sealed and unsealed pavement and concentrations of metals, polycyclic aromatic hydrocarbons, and radionuclides for soils, pavement dust, and stream sediment for 10 urban watersheds

These data represent a one-time synoptic survey of sampled soils, pavement dust, and stream sediment in 10 urban watersheds in three regions of the United States (Pacific Northwest, northeast, and southeast) to evaluate sources of sediment and two groups of common urban contaminants: polycyclic aromatic hydrocarbons (PAHs) and metals. Analyses of samples from six of the watersheds included fallout radionuclides to facilitate identification of sediment sources to the streams. Scripts used in R to test selected explanatory variables for the urban contaminants using Generalize Additive Models (GAMs) are included. The data release also includes Geographic Information System (GIS) spatial layers that were developed for...

Locations of sediment sampling sites, watersheds, and mapped sealed and unsealed pavement for 10 urban watersheds

These data represent the locations of sediment sampling, the associated watershed boundaries for those sites, and the extents of sealed and unsealed parking lot pavement within 10 urban watersheds. These Geographic Information System (GIS) spatial layers were used to estimate area of sealed and unsealed driveways in residential neighborhoods. The percentage of the watershed that was sealed pavement and the percentage of the sediment sample from pavement dust were used as explanatory variables in statistical models of polycyclic aromatic hydrocarbons (PAH) and metal concentrations in the streams.
