When we think about environmental challenges, we tend to think about polluted soil and the need for soil remediation or chemicals in the air and the need to remove these through industrial control. However, one of the other big challenges for an increasingly dirty and polluted world is groundwater contamination. As well as soil remediation there are specialist techniques for groundwater remediation. Let’s take a closer look.
What Is Groundwater Remediation?
Akin to soil remediation, groundwater remediation describes the complex processes used to treat and clean polluted groundwater, either by converting pollutants to safe non-harming products or by removing contaminants entirely.
How Is Groundwater Remediated?
The process is carried out using a three-stage approach: extraction and disposal, pumping and treatment and in-situ treatment.
Is Groundwater Remediation Similar to Soil Remediation?
Companies that deliver soil remediation such as Soilfix will use a similar approach to removing contaminants or making them safe. Both involve a mix of manual extraction processes and some chemical processes for cleaning.
What Are the Challenges with Groundwater Remediation?
One of the biggest challenges for remediation firms is to access the groundwater, extract it and then dispose of contaminants safely. Usually, companies responsible will dig sumps or boreholes. Manual extraction can also involve pumps, and these are very effective.
The biggest challenge after accessing the groundwater is to clean it in an effective, thorough and cost-effective way. Processes such as reverse osmosis are effective, but they can take months and are complex and expensive. The contaminated water elements then need to be safely disposed of through specialist routes and companies that focus on this as a service, but again, there is a high degree of cost and logistical challenge involved.
In conclusion, groundwater remediation is a hugely vital activity in an increasingly polluted world. As with soil remediation, groundwater remediation seeks to restore our environment to its original balance and preserve the ecosystem for it to continue to survive. After all, the world relies on clean water and soil to simply exist, so these vital functions cannot be taken lightly.
