“Quick Look” Trajectory Assessment of Phase 1 Battelle PMF Sources at Lye Brook Wilderness IMPROVE Site P. Wishinski & R. Poirot, VT DEC ° 9 PMF Sources From Phase 1 Battelle SA Study ° ATAD Trajectories (4/day, 5 days back) from NPS ° Daily Source Contributions Normalized by x 1/mean ° Source Compositions summarized graphically, 2 ways ° “High” Source contributions defined as > 2.5 x mean (= about highest 10% of Source days (out of 671 days) ° Incremental Probability = high day probability minus every (sample) day probability (blues= low prob.; reds = high prob.)

Notes: -Sources 1 & 6 are very consistent with concepts of “Primary” & “Secondary” MW Coal identified by VT & Clarkson at both Underhill & Brigantine. - Source 3 has strong crustal component, but also high OC & S, and a very high Ca:Al ratio. Possibly from local calcarious soil, (or road dust from) or a relatively nearby cement plant / lime kiln. Absence of Al might be related to analytical artifact? - Source 4 is similar to unknown EC/Pb/Zn source at Brigantine. - Source 5 is similar to a wood smoke source at Underhill, with Canadian forest fire influence in summer. Local wood burning may not show up in winter at high elevation LYBR site. - Source 7 looks like windblown dust, but high Al & no Ca may indicate influence from Al analytical artifact. - Source 8 is very consistent with Residual Oil Source identified by VT & Clarkson at both Underhill & Brigantine, centered around greater NYC area. - Source 9, with elevated NA, Mg, K & Br, from Hudson’s Bay & SE Coast looks like sea salt, but also has relatively high crustal elements – Al & Si?
