3 Types of Environmental Remediation

Pollution from various sources such as manufacturing, farming and mining can lead to environmental degradation. Ways to remedy this problem include three types of environmental remediation Boston MA. In general, these methods remove contaminants and pollution from the soil and water for the sake of human health, safety and the ecosystem.

Soil Remediation

Soil contamination poses a risk to humans and animals through direct contact and the introduction of contaminants to crops in the food supply chain. Methods to alleviate this include air sparging, encapsulation, or simply replacing the polluted soil with new soil. In addition, reagents can be added to the contaminated soil to render the soil more chemically stable. Soil remediation occurs in many different settings, including urban environments, quarries, mines and wetlands.

Surface Water Remediation

Stagnant surface water is most at risk for propagating bacteria and other harmful substances. Usually easier to deal with than groundwater pollution, the accessible nature of surface water still poses a great risk to humans and animals when contaminated. Surface water remediation is achieved using many of the same methods used for groundwater, including pumping and in situ treatments using chemical reagents.

Groundwater Remediation

As with surface water, groundwater can be contaminated through the surrounding land or through water tables located above and below. The land surrounding the groundwater could contain dumpsites and landfills that leach contaminants into the water, as well as farmland producing pesticide runoff. Groundwater pollution can often cause the most long-term and serious issues to the environment and people, one being harboring the E. coli bacteria. A common method of removing groundwater pollution is to use a submersible pump to pump out the contaminated water.

Healthy, clean soil and water are essential to a safe and healthy ecosystem. Fortunately, there are many ways to reverse contamination to these sources.
