Your tap water will have particular properties determined by where you live, the source of your water, and whether you have some sort of water softener or filtering system.
Softened water has higher levels of salt than plants prefer, and these salts can build up in the soil. My tap water, as an example, is from the public system and is considered ‘hard’ being that it has a high mineral content. Although, rainwater is preferable as it’s missing things like excessive minerals or disinfectant chemicals, as long as you live in an area that ain’t subject to extremely acidic rain. Notice that this can change the chemical properties -such as the pH -of the soil which can affect plant growth, If I use tap water consistently on certain plants, I can see almost white rings of calcium deposits sitting on the soil surface.
Nobody knows what actually was inside the water as long as the contamination from human activities just like car driving and industrial plant releasing exhaust fume from the chimney, in the end, rain water maybe good.

Sweet peas, garden peas and broad beans prefer rain water. Although they still grow when watered with tap water the results you get from watering with rain water are vastly improved. Rain water has a neutral pH. Nevertheless, there’re particles picked up in the atmosphere during a rain which offer nutrients to the soil that tap water does not have. People don’t water long enough to equal the soak of a decent rain, It’s usually softer than tap water and soaks in the ground deeper than a hose watering. Furthermore, chlorine and similar substances in mains water inhibit the uptake of nutrients and thus reduce plant growth and health.
Rain water is far superior.
It ain’t good for plants or us. Rain however is readily absorbed by the soil and contains quite a few more nutrients it gains from the atmosphere. Sahara. Water from our public utilities and even water derived from deep water wells lack many things. The barometric pressure of the soil and atmosphere are lined up perfectly to allow for the rain to be utilized to have best results. Normally, our current water systems do not possess the full nutrient profile it once did. Of course consider the barometric pressure during a rain storm. Our overuse of phosphates have helped to create soil that is out of balance. It’s a well we as a nation been using chemical pesticides since the mid 1940’s and studies have shown that it’s not very much what’s in the water but what actually is now gone from the water.

Rainwater is generally better.
They certainly may harm the beneficial microbes in your soil, that will reduce the benefit you should gain from those microbes. Bleach and such. May not harm your plants in the drinkable amounts, per se. Nonetheless, rainwater is probably pretty much devoid of minerals. I’m sure you heard about this. They required less water and grew better when I filtered the water. That’s right! It may contain chemicals via pollution, however, and your guess is as good as mine as to what those chemicals will do to your plants and soil microbes.
as long as your soil may need those minerals, well water. Has the potential to be better than rainwater, relying on your soil and the composition of the well water. Did you know that the minerals in the water may have come from the abovementioned soil first off, in part. Also, the minerals in the water may have come from those soil primarily, in part. Since your soil may need those minerals, well water.
Has the potential to be better than rainwater, determined by your soil and the composition of the well water.
