What is Environmental Remediation?
Environmental remediation is cleaning up hazardous substances by removing, treating, and containing pollution or contaminants from environmental media like soil, groundwater, and sediment. This process is crucial for protecting the environment and public health by reducing the presence of harmful substances[1][2][3]. Remediation can involve various methods categorized as ex-situ (excavation and ...

The Impending Phosphorus Crisis
Why is overuse of phosphorus problematic, and how can recycling wastewater help address the problem? The world is rapidly approaching a phosphorus crisis, which would have drastic implications for the global food supply because farmers rely heavily on it to enhance agricultural production. The use of phosphate fertilizers, which allows us to produce twice as much food as we could without it, has ...

Brownfield Site in St. Louis is Transformed Using MonoShield - Case Study
In 2009, the Green Street-led development team entered the site into Missouri’s Brownfield Development Program, a move that provided economic incentives to offset some of the site’s significant restoration costs, which included remediating impacted soil and groundwater and raising the building grounds above the river flood plain. Upon entering the program, site remediation commenced ...

What Is Managed Aquifer Recharge?
Water supply resilience in the face of drought and climate change is a key concern for the UK, as it is indeed for the rest of the world. It can be easy to fall into the trap of thinking that the UK won’t face water stress and scarcity issues, thanks to its famously damp climate, but experts have predicted that changes in weather patterns, rising temperatures, greater variability in ...

Pyrolysis Equipment For Recycling Waste Tires In Mexico
In accordance with reputable sources the United States disposes close to 279 million tires each year. Naturally, that number will not be matched by Mexico, but it provides an indication of methods challenging disposal of the waste tires can be. The issue of landfills becoming overburdened by waste tires can be a serious one. Not simply are appropriate sites for disposal becoming less and less ...

Remediating Soil While Preserving Soil Structure
The importance of soil cannot be overstated. It’s the basis of agriculture, and as a result, is a critical component of sustaining human life. According to the EPA: “Productive soils, a favorable climate, and clean and abundant water resources are all essential for growing crops, raising livestock, and for ecosystems to continue to provide the critical provisioning services that ...

Understanding Sonic drilling
What is sonic drilling? Sonic drilling is a technique that significantly reduces friction on the drill string and drill bit by using energy resonance to affect the soil structure where it contacts the drill string. This combination makes penetrating for a large range of soils much easier. Sonic drilling is most often used when the drilling is difficult and the integrity of the core sample is ...

Monitoring Water Quality in Groundwater Studies
Groundwater derives from fresh water, such as rain or melted snow. It seeps under the Earth’s surface level into the pores between rocks, sand and soil. The water can be stored in these pores for many years or released into a river or the sea when the storage area becomes saturated. Because groundwater can quickly become contaminated, groundwater studies must be carried out. This post will ...
