A couple of easy solutions to not having single use water bottles but not liking tap water:
(1) use multi use water bottles that are returnable with a very hefty deposit,
(2) use 18.9 litre (50 US gal) bottles that are returnable with a very hefty deposit and dispense into multi use water bottles or mugs. This is what I do, given the water in the ground where I live is skanky.
The Lake Superior municipal water (@ p. 6-7) water where I work is very good compared to many other municipalities – the chlorine is barely noticable, but still I’d rather drink the divine rather than the almost imperceptibly tinged. It helps that the source is relatively clean compared to most lakes. More importantly, when in town I do not want to ingest lead even if only in miniscule amounts. Older buildings and the downstream end of municipal delivery often still have lead piping, so although the municipality ph balances the water (acidic water increases corrosivity of lead), I’d rather go with the bottled spring water that leaves its treatment at deionization and reverse osmosis, without sodium hypochlorite (chlorine) and the possibility of lead.
But bottled water comes with its own concerns. In my area there are two wells that sell bottled water. Only one of them has never had a problem (significant bacteria led to the the other being closed down for a while, which led to the a bit of quid pro quo – the closed supplier delivered the open supplier’s bottled water to the closed supplier’s thirsty customers, which was a marketing coup for the open supplier).
There are several non-local brands of bottled water available in chain grocery stores, but up here they are either water from a municipal supply that has been further filtered to remove the trace chlorine, or they are from non-local out-of-basin aquifers that would not be replenished with the same water once it is used, which is a concern for the folks in southwestern Ontario near Elora who’s water is being taken out of basin by Nestle, and is a concern for folks on Superior which is being eyed by Ogallala region (although Superior is huge, it’s flow only only averages 2,100 cms (at the St. Mary’s River discharge); by comparison, the average flow of Niagara Falls is 2,400 cms).
Non-local brands also have a greater environment cost due to the increased pollution incurred through gas/diesel transport, albeit bottle water transport is only a small portion of consumer goods shipped about. All these little things add up.
Assuming that you can find a local producer with a good track records, the final thing to keep in mind is to not use a plastic drinking bottle that contains BPA, BPS or phthalates (some plastic Nalgenes are free of all these). Ironically, the ultra-light and easily crushed disposable plastic water bottles usually do not contain BPA, BPS or phthalates.
So ya pays yer penny and ya takes yer chance. I’d much rather the penny be paid by way of a little more effort (returning bottles) than by way of trashing the environment that we share with all other living things.
