I work for a large municipality water treatment facility, and we are putting lithium in your water

We started using a new formula in mid-2021. Just out of the blue a new supplier arrives one day and there was some training and process management and nobody asked any serious questions. It was in the midst of the vaccine rollout and the company actually terminated one of our techs who had spoken out against the vaccines. So nobody was willing to stick their neck out. Just go with the flow.

A couple months ago, one of my coworkers, a chemical engineer, told me he took a sample to a lab run by one of his buddies who works for a contractor for the Navy. They ran a full panel chemical analysis, and he says that the main difference is the addition of lithium carbonate.

There are several known side effects to include heart arrhythmia and psychosis. Could explain some of the things going on these days, such as SADS.
