Apparently Lindane and Aniline groundwater concentrations are slightly decreasing over time on the former Uniroyal Chemical site. Or at least they are somewhat decreasing in the areas tested which consist of the MISA (Municipal Industrial Strategy for Abatement) outlets into the Canagagigue Creek. The ongoing and likely forever legacy of this site are all the other toxic chemicals on site which will always leach/dissolve into flowing groundwater and migrate either off-site or into pumping wells (when they are running properly) where some treatment occurs before they are discharged into the Canagagigue Creek.
SOME of these other chemicals include the following as listed in this Progress Report as groundwater concentrations.

As a sidenote the concentrations plus incredible numbers of different compounds certainly indicate the presence of both LNAPLS and DNAPLS (free phase) whether or not Lanxess/MECP and other fellow travellors will confirm or not. Also [ug/l=ppb] =parts per billion hence all concentrations are parts per billion.
