Well water is dirty and yellow, and there is a lot of sand. Can I still drink?

My family is from rural Henan. When I was a child, every household had something we called "killing a well". This is a very simple lever principle. After a few presses, the clear spring water will flow out, and a small amount of fine sand will not be pressed into the bucket for precipitation, but sweet water. At that time, we didn't have a drinking fountain or buy mineral water, especially in summer, when the well was getting hotter and hotter, the children were tired and sweaty. They all picked up bowls and drank for a while to quench their thirst. At that time, the water depth was about ten meters, about fifteen years ago. Later, the water became more and more turbid and the sweetness was gone. It is said that groundwater has polluted the villagers' wells, reaching 30 to 40 meters or even deeper. This was about seven or eight years ago, and now the well is still there, but everyone will no longer eat the pressed water. Tap water came to the village, and the "pressure well" will eventually become our memory passed down from generation to generation. ,,,,, for you.
