Well of course there were/are DNAPLS on the east side of the Uniroyal/Lanxess property. How could there not be? Over the course of the sloppiest dumping, spilling and wishful thinking toxic waste disposal possible various waste streams were switched back and forth and rerouted many times. Eventually pretty well everything ended up everywhere. At the last TRAC meeting (June 19/25) there was a map/figure put up on the screen by the Arcadis rep showing chlorobenzene sources. The largest plume encompassed most of the RPE 2,3,4, & 5 pits along Uniroyal Chemical's eastern property line with the Stroh farm. There were of course both the off-site sources just south of Uniroyal (& a little bit west) as well as the west side of the Creek sources from the RPW lagoons.
Speaking now of just the large chlorobenzene plume on the east side of the site I wonder how many local citizens remember one of a number of Mickey Mouse "investigations" that allegedly occurred near there? Three nearby monitoring wells on the west side of RPE 4 & 5 displayed very high chlorobenzene concentrations repeatedly. Now of course these monitoring wells were between these two pits and the Canagagigue Creek without any known containment of any kind. Well OW-40 was at the top (northern) edge of RPE-4 and OW-41 was at the bottom (southern) edge of RPE-4. The third well was OW-42 and was located at the northern edge of RPE-5, all three of course on the west side of those two toxic waste pits.
My records show three test pits in and around OW-42 named TP (test pit) #14, TP #15 and TP #16. There is also a nearby Borehole named BH # 8. Funny to me how quietly the data (soil samples) from those test pits was kept quiet. Clearly there are DNAPLS beneath those two pits that were not excavated and removed when the pits were emptied and put into the Envirodome/Mausoleum in 1993. After all the Envirodome had already accomodated much more toxic waste than originally envisioned. How were they also supposed to dig deeper and remove the DNAPLS?
Then there is also the possibility of a surreptitious Interceptor Trench over on the east side. It kind of makes sense when the Ontario Ministry of Environment bailed out on the hydraulic containment of all aquifers by ignoring the shallow aquifer (UA 1, 2, 3) on the east side. Almost as if they knew what Uniroyal had done surreptitiously in order to save themselves greater costs by having to pump and treat the east side Upper Aquifers..
The DNAPLS intentionally left on the former Uniroyal Chemical site will ensure many more decades (centuries?) of slow leakage affecting both the Elmira Aquifers and the downstream Canagagigue Creek lifeforms. Perhaps unknown to us Lanxess or the MECP are researching methods of speeding up the slow leakage on site in order to restore the property to a more developable state sooner. Of course this will further damage all the downstream and downgradient receptors from benthic lifeforms, fish, wildlife and human beings but these may be viewed as merely collateral damage by sociopaths and psychopaths.
how far did the plume go under the Stroh Farm? percentagewise?
ReplyDeleteWho knows? Generally very little sampling of either soils or groundwater on the Stroh farm. That's how lying, dishonest polluters can claim they are unaware of contamination having travelled where they don't want it to. Simply don't sample for it plus drastically limit the number of parameters (chemicals) you test for. There was one sample of NDMA above criteria in a well along the roadway entering the Stroh farm in a DEEP aquifer. That surprised me because while not upgradient it certainly was cross gradient to groundwater flow.
