Examples of Pall's Understanding of the Site

In November 2007, Pall issued its "Phase 2 Report, Downgradient Groundwater Investigation of the Unit E Plume"

Included was a cross section analysis map and several cross section diagrams A-A' through F-F'. Focusing in on the overlapping cross sections A-A' and E-E' from MW-79s,d to MW-83s,d...

The two segments reflect the uncertainty of trying to model nature with too little data...

... especially when a gross mistake is made like using the wrong elevation for MW-83s,d being used for the diagram on the right (A-A'). Correcting the elevation and adjusting the supposed aquifer layers makes the results look even more arbitrary...

These examples point out the vast lack of understanding of the hydrogeology of the Pall/Gelman site and the resulting lack of understanding of the fate of all of the dioxane contamination.

Pall doesn't help their case when they have discrepancies in their interpretations of the aquifer/aquitard relationships... often within the same report... and when they show inaccurate well elevations. If this is an example of the due diligence that Pall uses to manage of the cleanup, everyone has reason to worry.

One wonders if the DEQ noticed any of these discrepancies. The 20071102-XsectAA elevation error should have been caught an corrected by Pall before they submitted it... and if not, the DEQ should have noticed it and had Pall correct it.

Some may say this is old news and these 2007 and earlier examples are not a current concern. However, the 20071102 cross sections are the latest ones for that area.
