Due to urbanization, there is a large increase in industries; these industries produce effluent. This effluent will alter the physical and chemical characteristics of the soil and water. A laboratory study was attempted to understand its physiochemical change in soil and water through a column study: it was conducted under the variable head condition for two different soils (in situ and sandy soil) and four different wastewater samples (RO water, treated and untreated municipal water, untreated industrial wastewater) for one cycle. The time taken for sandy soil is 3 h, and for in situ soil, it is around 6 days. The pH, specific gravity, conductivity, permeability and shear strength properties were all studied. There was not much change in the chemical properties of the water upon passing it through the column medium. But the soil contaminated with untreated wastewater shows a reduction in bearing capacity by almost 50%, making it unfit for construction.

工业和城市废水影响下的污染土壤的理化性质。

由于城市化，工业大量增加。这些工业产生废水。该废水将改变土壤和水的物理和化学特性。试图通过专栏研究来了解其在土壤和水中的理化变化的实验室研究：该研究是在可变水头条件下对两种不同的土壤（原位和沙质土壤）和四种不同的废水样本（RO水，处理过的和未经处理的）进行的。市政用水，未经处理的工业废水）进行一个循环。沙质土壤的时间为3小时，而原位土壤的时间为6天左右。研究了pH，比重，电导率，渗透性和剪切强度特性。通过柱介质后，水的化学性质没有太大变化。
