Watershed Characteristics and Polycyclic Aromatic Hydrocarbons in Urban Lake Sediments EVAN DART

Polycyclic Aromatic Hydrocarbons (PAHs) Compounds produced during carbon combustion processes Several classified as suspected or probable human carcinogens by the U.S. EPA Van Metre et al. 2000

Coal-tar Sealant PAH Contribution to Urban Lake Sediment Van Metre and Mahler, 2010

Coal-Tar Based Sealant Liquid sealant used to protect and beautify pavement Highly concentrated in PAHs (10% by weight) USGS; Van Metre, 2010

Study Determine if certain watershed characteristics affect coal-tar sealant contribution of PAHs in urban lake sediments ◦Twenty lakes selected from study by Mahler and Van Metre, 2010

Analysis Geospatial Data ◦Average Annual Precipitation ◦Average Slope ◦Impervious Fraction ◦Average Slope of Stream Network Statistical Analysis: Spearman’s Rank Correlation ◦Between PAH concentration data from the study and the watershed geospatial data ◦Coal-Tar Sealant PAH Mass Contribution

Data Sources National Elevation Dataset (NED30m) ◦Watershed Delineation ◦Average Hydrologic Slope ◦Stream Network Average Slope USA Mean Rainfall ◦Average Annual Rainfall National Land Cover Dataset (NLCD Impervious) ◦Impervious Fraction Sediment PAH Data (Van Metre and Mahler, 2010)

Geospatial Data Example

Spearman’s Rank Correlation Analysis

Average Annual Precipitation Spearman’s Rank Correlation Coefficient, ρ = 0.041

Average Slope Spearman’s Rank Correlation Coefficient, ρ =

Impervious Fraction Spearman’s Rank Correlation Coefficient, ρ = 0.277

Average Stream Network Slope Spearman’s Rank Correlation Coefficient, ρ =

Conclusions  No strong correlations between geospatial data categories and sediment PAH data  Unexpected trends  Possible Improvements ◦Larger sample size ◦Other geospatial data categories to consider ◦Coal-Tar Sealant Geospatial Data
