Things can be contaminated, and occasionally are, through the manufacturing process. I cannot speak to whether that is a possible venue to spread poisons. Brita filters are made of activated charcoal and pull contaminants out of the water. They will remove chlorine from the water. Really large activated charcoal systems are used to remove organic compounds like TCE and PCE from groundwater sources, so a Brita filter wouldn't likely be used to dispense poison. In terms of potency to make people sick- we moved 40 billion gallons of water a day so the poison would need to be dispersed over the entire system.

What about a water bottling plant? Would it be possible to inject the poison there? That would explain why not everyone got sick from it
Not trying to cling on to the theory but just trying to run through all the options.
Look at this video and you tell me. "https://www.youtube.com/watch?v=_ZybbjLgOuQ". What you don't see are the hundreds of sensors that test for impurities in the water.
