Why does the water in my well always turn yellow?

Water contains a relatively large amount of iron ions. In the well, because of deep hypoxia, it exists in the form of ferrous ions, which is light green, so you can't see it. After being drawn out, it comes into contact with the outside air in a large area and is oxidized into trivalent iron, namely iron oxide and rust, which turns yellow.

This situation should be analyzed in detail. If yellow is too strong and iron content is too high, it is still not good. You need to consider the filtration of the water purifier. If it's not obvious, it's not a big problem, but it's best to use fresh ones: because iron is absorbed by the human body in the form of ferrous ions, too much absorption is still harmful to trivalent rust.

It is suggested that friends who ask questions can use the fastest correct answer in time when they encounter the correct answer, so as to avoid other friends thinking that there is no correct answer before.

Adopting other people's answers is not only an affirmation of other people's labor achievements, but also an encouragement to respondents, and both questioners and respondents can gain wealth value. As the saying goes, there are many things, so why not?

If you think my answer doesn't completely solve your problem, or you have other questions, you can ask me questions or ask my team for help.
