Well Water Comes Straight from the Ground. Well water is groundwater that is untreated.
Well drillers drill down to the aquifer, which is an underground layer of permeable rock containing water.
If you happen to live in an area where wells are plentiful, or you even have one in your own backyard, the convenient access to what seems like fresh water could be attractive.
While there are many proponents of raw, untreated water, the benefits may not outweigh the potential risks.
Testing your well water annually for bacteria, nitrates, and pH levels. It’s also possible to install a filtration system.
Because the water hasn’t been treated, there’s a big chance of contamination – particularly from bacterial and parasitic infections like giardia.
While well water used to be the norm, there’s a reason that city water supplies and the regulations surrounding them were put into place – you simply don’t know what you’re getting unless you test or treat the well water yourself.
