Essay About Ground Water Pollution | Writing

Today, human activities are continuously adding commercial, domestic, and agricultural waste at an exponential rate to groundwater reservoirs. Generally, groundwater pollution is permanent That is to say, once it is polluted, it is impossible to recover the aquifer's original water quality. Excessive groundwater mineralization degrades the consistency of the water, creating an unacceptable taste, odor, and excessive hardness.
While the soil mantle through which water passes functions as an adsorbent with its cation exchange capability retaining a significant portion of colloidal and soluble ions, groundwater is not fully free from the danger of chronic contamination.
We have long believed that groundwater in general is quite pure and safe to drink. Therefore, it may be alarming for some people to learn that groundwater in fact may easily be polluted by any one of the following sources. The problem of groundwater pollution can be understood by two examples i.e. Love Canal episode (1976-77) and arsenic poisoning in West Bengal (India).
The consistency of the groundwater is reasonable in most cases and can be safely used without any elaborate treatment since the water undergoes natural filtration during percolation through the soil pores before being deposited in the groundwater reservoir. In addition, groundwater is normally free from suspended impurities and organic matter responsible for disease growth.
The groundwater is, therefore, less likely to be contaminated by bacteria. In some cases depending on the characteristics of the geological formations with which the water comes in contact, the groundwater may contain a large number of dissolved salts, minerals, gases, etc., which may impart different tastes, odors, and certain properties such as hardness, etc., to the water. However, the quality of groundwater may considerably deteriorate if it gets polluted.
