My RAC Delegation was two pages long and I read it to RAC last Thursday evening and after the meeting was over I e-mailed it to Lisa Schaefer, Support Person, for RAC and TAG. I might add that although there were some fairly strong comments in it, I actually self-edited at least a few gratuitous comments out of it during my reading of it and then immediately prior to e-mailing it off.
Oh heck I'm going to publish my RAC Delegation in its' entirety. Here goes!

MECP
Sediment and Fish monitoring Results
Good evening RAC and TAG members.
The report I am about to comment on is dated September 1, 2022 and
describes monitoring results from two years ago done by the
Environmental Monitoring and Reporting Branch (EMRB) of the MECP. It
is titled “Sediment and forage fish monitoring results from
September 2020 in Canagagigue Creek”.
Over the past 32 years I have read
literally many hundreds of so called “technical” reports from
Uniroyal Chemical, Conestoga Rovers, Morrison & Beatty, RMOW,
Lanxess, GHD, MOE/MECP etc. I am confident in saying that this report
is NOT the absolute worst of the bunch. Various legitimate
scientists, unaffiliated with Elmira, Ontario's biggest polluter,
have referred to some of these reports as junk science and psuedo
science. I prefer to generally think of them as quasi legal documents
being presented to mostly appreciative “fellow travellers” by
friendly defence lawyers. Hence they are often more subjective than
objective which kind of does pervert science if you think about it.
The MECP i.e. Ontario Ministry of
Environment appear to be somewhat urgently selling two narratives in
this report. The first narrative is what I call the real estate
theorem. That would be the well known “Location, Location,
Location” theorem. They are suggesting that most or all contaminant
concentrations are highest at the Uniroyal/Lanxess site and nearby
while decreasing as sampling occurs further downstream all the way to
the Grand River. This narrative appeals to Lanxess because it lowers
their cleanup costs in the Creek as they focus solely on their site
and at most a few hundred metres downstream in a five mile long
creek. It also appeals to busy citizens, uninformed or otherwise, who
find it intuitively logical that just as in groundwater, the highest
concentrations are nearest the source and the contaminant plume
diminishes with distance from the dumping source. We will get back to
this.
The second narrative of the Ministry
of Environment really surprised me. Since my personal discovery of
the Stroh Drain in 2014 running for approximately 125 metres parallel
and only thirty feet away from the Lanxess property line, all
friendly parties to Chemtura/Lanxess have done their best to ignore
it. Absolute refusals to test soils around the 450 metre waterway to
the Canagagigue Creek as well as three to four only sediment sample
locations from the bottom of the Stroh Drain over the course of this
450 metre long waterway diverting groundwater from Uniroyal/Lanxess
onto the Stroh and Martin properties has been blatant behaviour.
Hence my surprise that the MECP have jumped in where angels fear to
tread. They have categorically and repeatedly stated that the Stroh
Drain is NOT a source of contamination to the Creek. Well now!
I'm going back now to the MECP's
narrative about contaminant concentrations being a function of
Location, Location, Location. The simplest explanation as to why this
is wrong is that their own data, Figures and Tables contradict that
story! Yes there are instances in sediments where this does appear to
be so. Unfortunately there are just as many or more where contaminant
concentrations in sediment are HIGHER downstream than either at the
Lanxess site or the next closest downstream sampling location.
I was initially reluctant to give any
credence to the MECP's apparent belief that fish swimming in the
Creek could somehow be indicators of where the contaminants are
highest. A biologist mentioned in a following paragraph suggested
that for certain species, minimal travel could be possible. Also the
MECP clearly believe it to be so based upon their comparison of fish
tissue contaminant residues with location in the Creek. Unfortunately
the only way their bar graphs support this is when they are not
consistent in comparing tissue contaminants upstream and downstream
in the SAME SPECIES! In other words contaminant results for example
of common shiners increase with distance downstream but by putting
creek chub or bluntnose minnows into the sampling mix at the Lanxess
site and just below the Sewage Treatment Plant, the bar graphs appear
to show higher concentrations upstream. This is visually misleading.
I am not quoting specific Figures and Tables here due to a lack of
time allotted to me. Feel free to read and see it for yourselves.
There are other factors at work here
regarding any contaminant pattern in the Creek and the MECP know
perfectly well what they are. These other factors are well known and
understood by biologists and other scientists. Distance can be a
factor but it clearly is NOT either the biggest or only factor.
Particle size distribution as in sediment fines also determines TOC
or Total Organic Carbon. In other words locations with more clay and
silt versus sand and coarse sand will generally have higher TOCS.
Similarly these higher TOC values also correspond with higher organic
chemical contamination in these sediments. The MECP in this report
(pg. 6) blessed us with all of ten lines of text explaining TOC and
somehow they failed to mention its' significance to contaminant
concentrations being of greater importance than distance from the
site.
The second narrative of the MECP
regarding the Stroh Drain is also problematic. The MECP are clearly
backing Lanxess's fear and refusal to honestly sample the Stroh
Drain, Ditch & Berm (SDDB). Indeed technically speaking the Stroh
Drain is Not the “source” of anything. It is a partially man made
pathway and drain however. It is also NOT an “agricultural”
drain. Yes the Stroh property further north grows crops as well as to
the east but the man made drain which joins a natural creek,
sometimes
referred to as Martin's Creek, is well
treed at the north end and does not run through tilled fields on
either property. It is also partially diverted into the Martin's
swimming pond and perhaps the MECP and Lanxess fear liability issues.
The minimal sediment sampling in the Drain has revealed DDD and
dioxins/furans in excess of formal criteria. Dioxins/furans far in
excess of formal sediment criteria. Apparently minimal sediment
sampling at a much shallower depth than where GHD found 24.4 ppt
dioxin/furans, combined with wishful thinking and poor scientific
methodology has informed the MECP's opinion on the Stroh Drain, Ditch
& Berm.
I have also had a University level
biologist advise me that there are several issues with the
methodology in this report. It includes inappropriate bar graphs
versus point graphs, over interpreting of the data, opportunistic
sampling and inconsistencies in comparing contaminant concentrations
to location while using different species of fish simultaneously.
There are many other problems including misstated road names, phantom
creek chub being missing in the text listing species but then
appearing in graphs, references to upstream and downstream locations
in the Stroh Drain when in fact the MECP only sampled in two
downstream locations both beside the Martin pond and likely not more
than 75-100 feet apart and both very close to the Canagagigue Creek.
In hindsight this report is likely on a
par with CRA and GHD past poor reports. I have seen some good reports
from the MECP specifically from Jaimie Connelly, Bob Hillier and
Cynthia Doughty regarding groundwater issues. This MECP report
appears to be unsigned which I understand.
