In yesterday's post I expressed my skepticism based upon memory of claims that GHD made in their Introduction to their latest report titled "Revised East Side Groundwater Report". I've now looked at more of the data and I was correct hence my strongly worded title above. Thirty-two years plus of unadulterated bullsh.t from both CRA and GHD and one begins (Ha!) to lose one's patience. Indeed as I surmised NDMA is present above drinking water standards in a deep aquifer 240 metres east of the Lanxess/Stroh property line. Yes the most "consistent" NDMA exceedances are in shallow groundwater right on and along the border between the properties. Another GHD "error" in the Introduction is claiming that 2,4 dichlorophenol does not exceed its' drinking water standard (ODWS). In fact in well OW36-5(R) it does and interestingly the standard for 2,4 dichlorophenol is 900 parts per billion (ug/l) whereas the standard for NDMA is only .009 parts per billion (ug/l). Bluntly put NDMA while very toxic is only a very tiny amount of the toxic solvents and chemicals in Elmira's (and Stroh's) groundwater. .................................................................................................. Interestingly and surely by coincidence only the most relevant data in Table 6.3 is right at the very back of this one hundred page report. That is the data from both shallow and deep monitoring wells on the Stroh property, 240 metres east of the Lanxess property line. Indeed both NDMA AND 2,4 dichlorophenol are detected in these wells both shallow and deep aquifers i.e. 22, 24, 26, & 29 metres below ground surface. That is stunning information. Yes NDMA with its' very, very low ODWS (.009 ug/l) has concentrations exceeding it whereas 2,4 dichlorophenol with its' very high ODWS (900 ug/l) does not exceed its' ODWS. .................................................... There are many other contaminants above their drinking water standards along the Lanxess/Stroh property line that magically, once again disappear from further consideration. These include benzene which far exceeds its' ODWS of 5 ppb or ug/l. Other contaminants are in high concentrations but allegedly have no criteria to exceed such as acetone among others. There are a few high Method Detection Limits which understate detections encountered albeit no where close to as many as in earlier reports. As stated in the title it's all about the polluter/successor minimizing the extent of contamination especially off-site to reduce cleanup costs as well as public disgust with them.
