I use ac, dehumidifier water, and rain water.

most cities get their water from rivers and lakes. just google your local water com. it's all there what's in the water.

human poo is listed on everyone. no poo in the sky?

very few get well water, and well water translates to hard water, soft water, or whatever ferts and pesticides the farmer had run off his tobacco.

acid rain is the reason you test ALL water sources ph and ec. aquafina anyone?

please do not take offence. this is IMHO&exp.
