I predict it won't stand.

“We have received reports that some citizens have been hospitalized due to bacteria in the water. This is a serious public health concern that deserves immediate attention. If your water looks discolored, contains sediment, has a strong odor, or you have experienced related health issues, please send us a message. We are gathering information and reporting findings to the state.”

that is pretty solidly "free speech", not defamation, not allegations of anything, not "libel"‡

‡libel noun 1. a published false statement that is damaging to a person's reputation; a written defamation

Example: he was found guilty of a libel on a Liverpool inspector of taxes

-defamation -defamation of character -character assassination

2. (in admiralty and ecclesiastical law) a plaintiff's written declaration

verb 1. defame (someone) by publishing a libel

Example: the jury found that he was libelled by a newspaper

---- But law can be complex and "injustices" happen all the time, so we'll see...
