There's a lot of missing information here. I'm no fan of Tesla and I wouldn't be surprised if they are doing something inappropriate but there's a lot of unanswered questions here.

Why wasn't the sample taken at the outfall? That seems like such an obvious thing to do that there must be a reason it wasn't done. Is the outflow accessible?

What other facilities exist in the area? This is described as a ditch, not a creek or river, which implies to me that it is artificial. Is this an industrial area with other contamination?

> Hexavalent chromium at 0.0104 milligrams per liter, just above the lab’s reporting limit of 0.01 mg/L. Hexavalent chromium is classified as a known human carcinogen by the US National Toxicology Program. It is the substance the Erin Brockovich case was built around.

I'm not sure I am parsing this correctly. To the best of my understanding this means it is just above the noise floor? What was the exposure in the Erin Brockovitch case?
