The only way water after being distilled by the sun to pure H2O can be contaminated with these chemicals is if the chemicals are in the air. To my knowledge, we have zero regulations on what airplanes are allowed to spray into the atmosphere. Scientists at https://www.geoengineeringwatch.org/ and https://climateviewer.com/ have tested the aerosols and other chemicals being sprayed and found them to include a number of harmful chemicals. If enough people were aware of what is going on, we could demand some transparency and accountability.
