Something occurred to me last spring as I was preparing an "organic as possible" vegetable garden.
The water source is quite far from the garden. I use 2 x 100' hoses to bring water up. I realized that if it isn't safe to DRINK out of garden hoses, it isn't safe to have my veggies full of that water, either...especially 200 feet of it, lying in the sun! I also thought about what kinds of leftovers the hoses are probably made of, and what a variety of unknown poisons could be in them.
So, I went looking for a hose-END filter, and found one (can I mention brand names and web sites on here?) It's advertised to take out all sorts of impurities, including the lead and plastic (which we could smell and taste) and chlorine and its buddies (it's city water.) Sure enough, the difference in smell and taste was night and day. I used it all spring, summer and fall. I plan to get a replacement in a week or two, for this year's garden.
Sorry, being a newbie, if I've posted something everyone already has talked about enough. Just remember that the filter is needed at the END of the hose, just before the sprayer or sprinkler, etc.
