DECEMBER 2018 LANXESS PROGRESS REPORT

I believe that I have previously posted regarding the extent of off-site pumping in December. It is at historically excellent levels although not remotely close to either double or triple as promised initially in November 2012.

Surface water in the Canagagigue Creek continues to surprise. Conductivity increases from the upstream end of the creek just above Lanxess (Uniroyal) to the downstream end. PH decreases which indicates increasing acidity of the water. None of this is the surprising part. Table C.2 indicates that various chlorophenols and cresols have higher average concentrations in the creek upstream than downstream over the last three years. That is both odd and concerning and may indicate that the Bolender Park Landfill is and has been discharging to the creek. With volatile organics (VOCs) only benzene and toluene have higher concentrations downstream than upstream which is not surprising. Base/Nuetral Extractables (BNAs) are more peculiar however. Aniline, carboxin, NMOR and BEHP all have higher concentrations upstream than downstream. Again I suspect the Bolender Park Landfill.

Figure D.1 should embarass Lanxess and GHD. It purports to show groundwater contours in the Surficial Aquifer (SA) on Lanexess's north-east corner. Unfortunately it fails to indicate the already admitted by them flow of SA groundwater eastwards onto the Stroh property.

Figure D.3 should also be embarassing. It shows ridiculously low head differential (ie. water level difference) between the Upper Aquifer (UA) and the surface of the creek for half of the observation wells. This indicates that hydraulic containment of the UA is marginal at best.

Table F.1 indicates the thickness of LNAPL (light non aqueous phase liquid) floating on the water table in Lanxess's south-west corner. It ranges over several wells from black tar-like blobs present on the probe to half a metre in thickness. This LNAPL was discovered in 1995 and belatedly presented to UPAC many months after being found.It is disgraceful that it has not been removed in over twenty years. Monitoring doesn't cut it and neither do excuses.
