The third episode involved getting a hydrologist to determine the source of the chemical contamination. So they are going to drill some test wells to determine sub-soil water flow. So... why would you use a core drill intended for testing pavement and poured concrete with a drill depth of less than half a metre for such work? You really need to drill a lot deeper. Must have been what the contractor's rental shop had. Then the generator powering the drill changed from a small less than 2 KW unit to a larger one in the back of pickup. (OK I am a engineer, I do have some idea of how this works)
Then they have some computer plot of the contamination density, and that was got by using only 4 samples??? I need that software..
Then they find the mother load, fuel drums underground, with bad stuff in them.. The hazmat company lifts the full containers onto a truck using a magnetic coupling to the hoist. Lets see, the water content of a fuel drum is about 208 KG, but perhaps more like 175 KG for contents if oil like. add back about 20 KG for the drum, so about 200 KG, If a magnet is used, that means the drum is steel. What does steel do when in the ground... RUSTS!, So they manage to lift a 200 KG drum using a magnet, connected to the thin metal top that would likely deform at best (reducing the magnet coupling strength), and if rusting, would perhaps just pull off or open...
They are thinking it's benzene, the materials safety sheet for that material does not indicate anything about what is manifesting in the exposed girls.
They need some better resource people to check a few facts
