Water gets filtered naturally when it flows back into the earth and recharges underground aquifers. As the water particles travel through the ground, it is naturally “scrubbed” for contaminants and larger particles. The natural process isn’t 100% proof, however, as some chemicals linger residually in the water, which makes it not entirely safe for drinking immediately.
Water is also semi-purified when it evaporates and is taken up by weather systems and is then deposited as rain water. This process filters out larger organic particles, but does not necessarily remove smaller organic particles or pathogens such as bacteria and viruses.
yea underground there is only enough space for water/liquid
to pass through but chemiclas can harm the aquafyer
