Waterpic, who make water based electic 'flossing machined', also make a machine that used ozone purifided water to wash vegetables.. (for the parinoid!)

and a huge ozone generator is used by NYC to clean water from the croton aquaduct, the city's oldest. the water is run throught sand and diazomized earth, and is perculated with ozone.
that, plus a small shot of clorine is all that is needed- and only now, that the area around the reservoir is getting 'built up'. the new reserviors, (in more remote parts of NY) just need filtering and clorine.
