This article appears to be about the false claim that the water-deluge system (which sprays water to protect the launch pad from heat and to dampen noise) was "industrial wastewater". The headline is pedantically true because environmentalists did say it, but is definitely and intentionally misleading.

The water is being used to cool the launch pad as Starship’s engines fire. While drinking water may be used in the system, after it comes into contact with the rocket exhaust, it contains high levels of dissolved solids and potentially toxic chemicals like zinc and hexavalent chromium, according to the license application submitted by SpaceX to Texas regulators.

There doesn't seem to be any reason to suspect SpaceX's claims about the contamination so it sounds like they're not running afoul of any state regulations. It's worth noting that they did pay a related fine to the EPA but that doesn't appear to be due to their practices: > The subsequent fines levied on SpaceX by TCEQ and the EPA are entirely tied to disagreements over paperwork.

  I looked at the license application that was linked to, and while it contains many tests measuring zinc and hexavalent chromium, none of them are "high levels" (as compared to EPA standards for drinking water).
