Migration Pathways
Migration pathways include pore spaces (e.g. in sands or gravels), fractures, joints, bedding planes and fault lines. Anthropogenic influences can increase permeability, for example, by activities such as mine grouting, air blast rotary drilling, blasting and mining. All of these can have potentially catastrophic effects on pathways and ground gas movements. In addition, anthropogenic ...

The latest ground Gas monitoring innovations
The latest Ground Gas monitoring innovations The traditional methodology for ground gas monitoring has been ‘spot monitoring’ – taking event readings at various set times to predict the sub surface gas regime on both on Brownfield and Landfill sites. This methodology is in general current practice under both the EU Landfill Directive 1999/31/EC which is supported by ...

Subsurface Gas Monitoring
So, what can be done to mitigate the potential drastic effects? Whether a landowner, developer or regulator the objective is identical; namely to ensure that any existing or proposed development remains or takes place safely. But because of the temporal or seasonal effects on ground gas migration, monitoring has to be undertaken over a potentially wide geographic area, lasting several ...

Points for Attention in Design of Tank Grounding System in Gas Station
Points for Attention in Design of Tank Grounding System in Gas Station: 1. Oil tanks should be lightning-proof grounding, and grounding points should not be less than two. 2. The buried oil tank should be electrically connected with the process pipeline exposed to the ground and it should be grounded. 3. The information system of gas station should be equipped with armoured copper earthing cable ...

Life Among The Heavy Metals
Authors in scientific and applied works interpret the meaning of the concept "heavy metals" in different ways. Today, they include more than 40 chemical elements with an atomic mass of more than 50 atomic units. An important role in the determination of heavy metals is played by the following conditions: their high toxicity in relatively low concentrations, and the ability to bioaccumulation. ...

Corpus Christi, Texas - excavation; open-hole chemical oxidation
When a motorist struck the drop hose of a fuel tanker making a delivery at this Corpus Christi, Texas convenience store, about 250 gallons of gasoline flowed across the surface to a grass area where it soaked into the ground. The sidewalk and a natural gas pipeline prevented local cleanup crews from removing all of the contamination immediately after the spill. Over a period of several weeks, ...

12 things you should know about Benzene
Benzene is a chemical that is a colourless or light yellow liquid at room temperature. Benzene evaporates into the air very quickly. Its vapour is heavier than air and may sink into low-lying areas. Benzene is the simplest aromatic hydrocarbon and distinguished as the first aromatic hydrocarbons with the nature of its bonding first established in the 19th century. Benzene is ...
