Preventing Acid Mine Drainage: Role of Digital Temperature Sensors
Acid mine drainage (AMD), also known as acid rock drainage (ARD), is a significant environmental concern arising from the exposure of sulfide minerals in mining waste to air and water. This chemical reaction, driven by the oxidation of sulfides, leads to the generation of highly acidic waters and the release of toxic heavy metals, wreaking havoc on ecosystems and water quality. AMD’s ...

Optimizing Temperature Monitoring for Artificial Ground Freezing Projects with Digital Thermistor Strings
What is artificial ground freezing? Artificial ground freezing is an engineering technique that is commonly used for groundwater control and/or excavation support for shafts and tunneling projects, and mine sites1. It involves drilling closely-spaced pipes into the ground and then running coolants, such as chilled brine between -25 °C and -35 °C, through them to extract heat from the ...

What Are Phosphate Magnetic Particles?
Phosphonates or phosphonic acids are organic compounds containing C–PO(OH)2 or C–PO(OR)2 groups (where R = alkyl, aryl). Most phosphonates are highly water-soluble, while phosphonic acids are only sparingly soluble. Phosphonates are not volatile and are poorly soluble in organic solvents. Normally they are more efficient FRs than phosphates, but raw materials for phosphonates are more ...

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 ...

Vinyl Chloride Bioremediation In Central Ohio - Case Study
Site Summary: CL-Out® bioremediation removed vinyl chloride and other chlorinated solvents found in ground water at a former automobile repair shop. The solvents were thought to have been released from an underground storage tank (UST). After the UST and associated contaminated soil were removed, CL-Out bioremediation was implemented to reduce the levels of contamination to site-specific ...

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 ...

NMR Investigations in Coastal Ecosystems by Darya Morozov
Coastal ecosystems play an important role in interfacing between marine and terrestrial environments. These systems host complex dynamic processes associated with strong physical gradients between freshwater and saltwater, ground water and surface water, and between high and low permeability soils. Therefore, the structure and stability of coastal environments have a critical impact on ...

Outfall Tunnel Ground Freezing - Case Study
The shafts for an outfall tunnel in New York required shoring for excavation support and groundwater control. Since there was limited room at site, ground freezing was selected to provide the shoring, instead of a diaphragm wall. Ground temperature monitoring was a critical component, to allow for modeling of the freeze bulbs and to verify when it was safe to begin excavation of the shaft. ...
