As someone who dealt with government agencies for decades I can echo what others have said: Check with county officials first.
In theory, the TCEQ should be all over an inadequate water treatment system. If it was a refinery or chemical plant, they'd be camped out there tomorrow morning. But I've called them before on some really bad violations, and if they think they're going to have to do a lot of work (like drive out there one day) or that there isn't a potential for giant fines, they'll somehow never get around to it.
