What measures to protect water and air help keep people healthy?

Clean water and air are essential for human health, and any human activity can pollute both water and air. Therefore, there are measures that help fight pollution. So, for example, we have water treatment facilities that help purify and disinfect drinking water. This measure helps to reuse water. Also, in various factories, filters are required, which also help in the purification of water and air. There is a special commission that takes samples of water and air, based on the results of which it draws conclusions whether the enterprise is working correctly and according to all standards. And if there are violations on the part of the company or the plant, then they are obliged to eliminate the shortcomings and pay a fine.
