Just about any public water supply is not really too fit to drink. Granted, it is relatively safe but there is much you may not know about. Just because it looks clear and clean does not mean that it is. What comes out of the tap is usually heavily treated and it can still be contaminated.
The only way to find out if your drinking water is as good as it could be and the only way to identify any real problems is to have it professionally tested by experts in the field. You can find a water company in md to do this for you. They will test it and then offer practical solutions.
The best thing to do is get a home filtration system. This will be the sort of thing that will cleanly filter all of your home water supply so you have perfectly clean water for drinking and for bathing as well as for watering your gardens. It really makes a big difference in the water you are exposed to.
While you may think that your tap water is perfectly safe and fine for drinking, you may not fully understand the negative effects of the chemicals that are put into your water supply to make it what is considered safe. In reality, it is not that safe at all. Things like fluoride and chlorine can impact health.
For example, exposure to large amounts of fluoride, such as in tap water, can lead to depression of the thyroid gland. This has been scientifically proven time and time again. Fluoride, though it can be good for your teeth, is bad for your body. It can totally wreck your metabolism causing weakness and weight gain.
Aside from this, there are all sorts of microscopic lifeforms that can get into your water. You do not know they hurt you until it is too late.
