ELMIRA = DOGPATCH = ASTOUNDING MENTAL GYMNASTICS TO DENY & DEFLECT DNAPL CONTAMINATION OF OUR DRINKING AQUIFERS

 

My renewed DNAPL education continues.  As mentioned yesterday I am somewhat surprised by the large number of factors determining how much free phase DNAPL ends up somewhat captured by filling pore spaces as Residual DNAPL , which can still slowly dissolve into the groundwater, as well as  then how much free phase DNAPL can continue migrating via gravity either vertically downwards or laterally (horizontally). Again this horizontal DNAPL flow depends upon many factors including the slope of the somewhat horizontal surface, the hydraulic head (i.e. ongoing pressure from the source area as DNAPL is continually refreshed from dumping chemical liquid wastes), the size of the pores between clay, silt and sand lenses and so many more.

I have written previously that both DDT and Dioxins and so much more can be mobilized by DNAPL. This is not an opinion but fact determined by geoscientists and other unbiased experts in the field. Furthermore with multiple sites on the Uniroyal property with proven DNAPL presence (M2 at OW88, RPE-3, TPW-2, RPW-5 ) including small quantities of DNAPL having been removed, there simply is no wiggle room left for the guilty parties. 

Eventually over time groundwater will very slowly dissolve dioxins, DDT and other nasties which will end up in detectable concentrations in our groundwater. Despite the low solubility of these compounds nevertheless Dioxins for example have a Solubility concentration in the low parts per trillion (eg. 15-20 parts per trillion  i.e. 15-20 ng/litre). Unfortunately the Ontario Drinking Water Standard for 2,3,7,8 - TCDD  (Dioxin) is only 15 parts per quadrillion  i.e. 15 ppq) .  Parts per quadrillion are a thousand times smaller than a part per thousand which is very close to the solubility concentration of Dioxins in groundwater.

Continued reliance on GHD, the Ontario MECP and Lanxess Canada may be ideal if permanent contamination of our Creek (the "Gig") and our drinking water aquifers is acceptable. If local politicians are willing to stand up and publicly declare that is what they have decided then so be it. But continued lying is no longer a viable option and such an option will continue to deteriorate as we get to the 2028 deadline.
