Hi everyone. I'd just like to make the comment, that rainwater is not immediately of drinking water quality (due to air pollution), and also there are problems during catchment that can make the water polluted and unusable even for nonpotable uses (contamination from collection surfaces).--Ivangiesen (discusscontribs) 14:59, 16 June 2020 (UTC)
