Groundwater pollution is one of the many environment-related severe issues the world is facing right now. The immediate consequence of groundwater pollution is depletion of freshwater for usage by humans. Humans highly depend on groundwater for personal usage and irrigation. Usage of contaminated water gives rise to many health issues. Also, contaminated water used for irrigating the fields has a direct effect on the quality of agricultural produce as well.
The most common causes of groundwater pollution are listed as follows:
Use Of Excessive Fertilizers
The accelerated use of agricultural chemicals or nitrogen-based fertilizers has helped to increase agricultural production in the last 20 years. The nitrogen in the fertilizers mixes with the soil and helps to improve land fertility. However, the excessive use of fertilizers has also contaminated the groundwater at a rapid rate. The nitrogen-based chemicals mix with the groundwater and form a high level of nitrates, a harmful chemical. The nitrate level in the groundwater is at an all-time high, making it unfit for use. Use of such water for irrigation gradually reduces the fertility of the land. People using such water for personal use and the animals consuming such water are prone to many health issues.
Use Of Excessive Pesticides
Pesticides help to save agricultural produce from pests. It then seeps into the ground, mixes with the groundwater, and makes it harmful for any use. Pesticides are highly toxic. Any direct or indirect contact or consumption of these chemicals can result in both chronic and acute health problems. People often use high levels of pesticides to get rid of the pests from their field. They do so to get good agricultural produce. However, unknowingly they are allowing more chemicals to seep into the ground and contaminate groundwater by mixing in it.
Direct disposal of untreated wastes on the ground or in rivers and streams is one of the major reason for groundwater contamination. The untreated wastes release toxic chemicals into the soil which seep into the ground and mix with the groundwater and contaminate it for any further use.
Industrial wastes often include heavy metals which are highly toxic in nature. The direct or indirect consumption of such heavy metals can be life-threatening for humans as well as the animals.
Here are a few ways to treat contaminated groundwater:
Physical treatment involves pumping out the contaminated water for chemical or biological treatment. Treating the polluted water with chemicals breaks the pollutants to make their effect less harmful. Another technique involves blowing air into the ground to bring the contaminants up with the rising bubbles and is gaining popularity for physically cleaning the groundwater. This technique is termed as air sparging. Other physical treatments include vacuum or oil skimming machines for contaminated groundwater treatment.
Introduction of micro-organisms or inoculation is used to treat contaminated groundwater biologically. The micro-organisms degrade the contamination level of the groundwater by increasing the biological activity in the soil and the water. With the help of increased biological activities, the pollutant level is reduced to a great extent. Planting of trees can also help in reducing contamination of water and soil as certain trees can absorb pollutants like arsenic, mercury, and selenium. Natural treatments are more eco-friendly than other treatment methods and also cost comparatively less.
Chemical oxidation is used on a large scale to break the molecules of the pollutants with the help of chemical liquid or gas. With the use of chemical treatments like chemical precipitation, ion exchange or carbon absorption, heavy metals can be easily stripped from the water. These are used to control industrial spills which are loaded with heavy metal contaminants which require immediate control and reduction.
