Here is a report that you might find interesting. You could contact them about your water.
Taste is an interesting thing. When I was younger, my mom felt the same way as you, and so we’d drink a lot of bottled water. I thought tap water tasted bad back then, too. I live in Hawaii and our tap water is some of the cleanest in the world since it is almost entirely groundwater. I exercise a lot, and found myself stopping at public water fountains often. Eventually, I didn’t like throwing away the plastic that the bottled water is packaged in and quit buying it. Now, when I drink bottled water, it tastes terrible to me.
Moral of story: Taste for filtered water can definitely be an acquired thing.
The water in your area is primarily from surface sources which means it is exposed to the environment and doesn’t get filtered naturally through the ground. It is treated extensively to remove bad stuff, and likely heavily chlorinated due to a new EPA rule that took effect at the end of last year. Your water is fluorinated also.
I can understand wanting to remove both the chlorine and fluorine because neither is good for your health. I know activated carbon is an effective means for removing chlorine and any byproducts of it from your water. This is a simple, inexpensive, and popular technology for water filtration. If you are one of those people that believes fluoride in water is good because it helps prevent cavities, then you can stop there.
If you consider fluoridation an unnecessary health hazard, I am not sure that carbon will remove it. Reverse osmosis most certainly would. And as others have pointed out, you can install a system in your home to do this.
White spots on your teeth sounds incredibly strange to me. I’m not sure if you mean the color of your teeth actually change or if you notice some kind of chalky build up on the surface of the enamel. I’d guess it is from minerals in the water? You should contact the water department and ask them about this.
I have no scientific data to back up this claim, but in my experience I feel like water that has been contained in plastic of any kind, particularly if it is exposed to heat/UV/sunlight tastes awful. It would seem that the plastic leaches something into the water that affects the taste. I don’t like the taste of water that has been in plastic at all. All of the storage containers in my kitchen are glass (albeit w/ plastic lids) – no Tupperware – so I understand where you are coming from. Plus, glass is easily recycled and doesn’t emit harmful toxins when heated like plastic does. Plastic is so much worse for the environment in a number of ways.
Most residential water filtration systems use filter cartridges made of plastic. Even if you go to a supermarket to buy filtered water from a machine, the water may have been in contact with plastic within the machine itself.
Besides all of this, it is becoming more and more popular to design indoor plumbing systems using plastic pipes because plastic is so much easier to transport and work with. If you live in a condo that was built recently, it is very possible that the water piping is PEX. Not sure about piping between water treatment facility/reservoirs and the building…maybe someone else on here knows?
If you want to continue buying filtered water from the store, you may just want to compromise and transport it in plastic (it is much lighter and more durable after all), then store it at home in glass…
