Pall/Gelman Dioxane vs Old City Landfill - dioxane plumes
from Google earth mashup
Both plume sites are about the same distance away from the estimated 10-year groundwater travel time boundaries for the Steere Farms Well Field - Wellhead Protections Zones (yellow) but the old city landfill plume has much lower dioxane levels which have decreased since 1997 and is moving away from Steere Farms while the Pall/Gelman plumes have much higher dioxane levels and are increasing is unexpected areas and have at least one offshoot that is moving southwest or south towards the Steere Farms wellhead protection zone.
