For the record, because long history of observation has taught me to never trust Tesla or its vendors: there does not appear to have been an independent investigation by environmental authorities. Palo Alto Fire Dept. was present for a bioassay sampling, but that's as close as it gets.

The fullness or emptiness of the cup—and what it ‘means’—is a contingent & unstable social production via a wide range of semiotic (especially linguistic) processes.

I will never forget the time I had to go pick up a bioassay that had been left in a local library book drop. Oh, the sad laugh the librarian and I had. Particularly sad on the grounds that it had worked and the urine had gotten to me.

Eh, your real problem is sensitivity. Short of the bioassay group, no one's gonna notice.
Of course, as a health physicist, if you'd pulled that on me you'd have gotten to drain that toilet, boil the contents, and count the ash. And you'd have been forbidden to pee in the meantime.

In general, ingestion/inhalation (unless it’s something AWFUL) generally just results in bioassay - you pee in a cup so they can figure out an internal dose estimate, but most stuff clears via regular excretion with no intervention needed.
