How deep is the pollution of chemical plants to groundwater?

The depth of influence on groundwater depends on many factors, as follows:

1, types of pollutants. Different kinds of chemicals have different effects on groundwater. For example, some substances will be adsorbed or decomposed by soil and rocks in groundwater, so the pollution to groundwater is less. However, some substances will go deep into the groundwater layer and pollute the groundwater more deeply.

2. Concentration of pollutants. The higher the concentration of pollutants, the more serious the pollution to groundwater. High concentrations of pollutants may make groundwater unusable or require more complicated and expensive treatment.

3. Depth and velocity of groundwater. The depth and velocity of groundwater will also affect the diffusion and influence of pollutants. If the groundwater layer is shallow and the flow rate is fast, the pollution caused by chemical plants may spread faster and affect the surrounding groundwater.
