A counterpoint is this
The lab tested for chromium in two ways: one test (ICP) measures all chromium of any kind, and the other measures hexavalent chromium specifically. The ICP test returned a concentration that was an order of magnitude smaller than the hexavalent test. That is to say, the tests contradict each other (because the whole is smaller than the part), and are both at the bottom of range for the tests performed.

If an ICP assay says the total chromium is an order of magnitude less then we can safely ignore the specific hexavalent test, which is a more difficult and less precise measure. I didn’t even look at that.
Everything about this says bad science and motivated reasoning intended to fool people unsophisticated about this type of thing.
Fair comment re hex. Elevated levels of some other elements need to be similarly reviewed.
These types of permits should really need to be discussed in town forums, regardless of the outcome here.
