I'm not planning on consuming the hose, but I think I'll drag out my RV drinking water hoses.
I tend to agree with Glenn. The manufacturers of RV drinking water hoses (Camco, Valterra, etc.) manufacture hoses with materials safe for drinking. However, if water does not sit inside a hose where these materials can go into solution its not likely that drinking from a garden hose as many did when we were children is not likely to be all that harmful to one's health. In high school chemistry class back in the day we made "shiny" dimes with mercury. Now, if the smallest amount of mercury is spilled they bring in a suited hazmat team to clean it up. And back then anglers often used their teeth to compress those tiny lead clam-shaped weights onto fishing lines. Older water systems still have leaded joints which are typically replaced by utility crews when discovered during routine maintenance (usually, when the pipes are excavated to repair a leak). And many older homes have copper pipes with lead sweated joints. It's wise to use the appropriate materials when making purchases of items intended to come into contact with consumable products. I personally avoid using glazed pottery made in certain countries sold in chains like Walmart. But a lot of the warnings on products are pure legalese. I'm more concerned with Alzheimer's being a problem than lead poisoning. And there are documented cases of people dying from consuming too much alcoholic beverage and even too much pure water. I would also note that the U.S. EPA (which does have an influence on similar agencies in Canada and elsewhere) is constantly adding to its list of "contaminants of emerging concern." Among these are hormones commonly found in birth control pills and other drugs, notably antibiotics, which are fed to livestock. All these products are excreted and since ALL water is recycled, end up in the water supply. There is virtually no place in the populated parts of Canada or the US where these chemicals cannot be found in the drinking water supply.
