And the mercury value of 0.133ug/l is the detection limit of the test. So what the rapport is saying is that there is no detectable mercury in the water.

SpaceX have since published a second statement confirming that there was a typo in the report, and stating that the mercury concentration is below detectable levels in most cases: https://x.com/SpaceX/status/1823378186836889699

Expand for tweet contents:

CNBC updated its story yesterday with additional factually inaccurate information.

While there may be a typo in one table of the initial TCEQ's public version of the permit application, the rest of the application and the lab reports clearly states that levels of Mercury found in non-stormwater discharge associated with the water deluge system are well below state and federal water quality criteria (of no higher than 2.1 micrograms per liter for acute aquatic toxicity), and are, in most instances, non-detectable.

The initial application was updated within 30 days to correct the typo and TCEQ is updating the application to reflect the correction.

So, pretty much what you surmised.
