“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?
