INTERCEPTOR TRENCH REFRESHER COURSE

 Slurry walls, interceptor trenches, the Waterloo Wall etc. are all variations of a type of remediation for contaminated groundwater. Some of these "walls" may have iron filings for example which interact with various chemical contaminants in groundwater. Hence the groundwater is in a sense filtered by the chemical interactions as it works its way through the wall. Some slurry walls may actually be for the purpose of stopping groundwater flow or even funneling or changing its' direction. Interceptor trenches can be for the purpose of redirecting contaminated groundwater possibly for treatment or discharge elsewhere. Interceptor trenches can also have chemically reactive components in them to effect treatment of passing contaminated groundwater.

Google Earth maps, satellite photos as well as simple aerial photographs have exposed some weird sh.t on the surface of the former Uniroyal Chemical site. Basically it is a series of straight lines running from north to south over on the east side of the Uniroyal/Lanxess site.  They then run south-east over to the Stroh property due north of where the steel conduit protrudes from several feet below grade and discharges into the extreme north end of the Stroh Drain, Ditch & Berm. (SDDB). 

Logically and practically it makes sense for Uniroyal Chemical to have constructed this bypass if you will. Shallow groundwater flowing westwards downhill from the east side waste ponds (RPE 1-5) towards the Canagagigue Creek appears to have been intercepted and via gravity flow redirected south and east to the Stroh property. To date any "explanations" from either the MECP or Chemtura/Lanxess have at best been pathetic and at worse patronizing bullsh.t.   

Further lending credence to the likelihood of this being a form of Interceptor Trench are drawings submitted to the Environmental Appeal Board by Uniroyal Chemical suggesting that the east side waste pits didn't need to be excavated as their contaminated migrating groundwater could be contained via these trenches presumably for later treatment. Hmmm???  

A serious *Responsible Care company would have fully answered these questions eight years ago versus still not yet.
