1. If we continue to drill wells in an unscientific and unprofessional way, the local water veins will eventually be seriously damaged and the groundwater may be seriously depleted. This is because over-exploitation of groundwater will lead to the decline of groundwater level, affect the natural recharge of groundwater, and may eventually lead to the depletion of groundwater resources.
2. The exhaustion of groundwater may also cause the problem of land subsidence. After groundwater overexploitation, the water in underground pores decreases, which leads to the decrease of ground bearing capacity and may lead to ground subsidence.
3. The depletion of groundwater may also make cultivated land drier and difficult to grow. Groundwater is an important water source for farmland irrigation. If the groundwater is exhausted, it will directly affect farmland irrigation, thus affecting the growth of crops.
Therefore, the harm of drilling wells 100 meters in rural areas is very serious and needs to be paid attention to by the masses. Scientific methods should be adopted when drilling wells, and factors such as local geological conditions, groundwater level, geographical location and water quality should be comprehensively considered. In case of doubt, it is recommended to consult professional geological prospectors or relevant departments.
