Groundwater Remediation Techniques

Water is the earth’s greatest natural resource which should be preserved and purified for various uses. According to the Environmental Protection Agency,

a�?Water is essential for life as it plays a vital role in the proper function of the earth’s ecosystems.a�?

Hence, it becomes imperative to preserve and utilise the wonderful natural resource in a thoughtful manner. Water remediation is the technique of eliminating the water supply of any contaminants. It makes the water suitable for human ue and consumption.

Along with rendering the water safe for humans, this technique of remediation ensures that the eliminated wastes removed from the water is disposed in such a way that it has a least harmful impact on the surrounding environment. Many different ways are employed to handle water pollution and restore the condition of water for usage.

Groundwater Treatment Techniques

Groundwater treatment starts with finding the main source of any possible contaminants. Then, you should find a certified or professionally trained technicians to oversee the remediation process. The remediation techniques depends on the scale and severity of the contamination. Factors like the time period and costs depends on these two factors.

Several remedial process are available according to the local conditions. Some of the different remedial techniques are mentioned below:

  • Pump and Treat Method:

    This method employs pumping the contaminated groundwater to an treatment facility located above the ground. Then, the toxins are eliminated and released near or at the surface. This cleansed water then gradually seeps back into the ground.

  • Hydraulic Treatment:

    This method pumps the water from an aquifer in such a way that perfectly collects impure water from wells that are used for agriculture or drinking purpose.

  • Air Sparging:

    This treatment method forces highly compressed air into the groundwater. This forces the impurities to form a vapor layer. This layer is formed above the groundwater and can be easily removed.

  • Permeable Reactive Barriers:

    These are trenches that are backfilled with filtering agents such as iron fillings or activated carbon. The contaminated groundwater flows through these and the contaminants are filtered out.
