Using a Ternary Diagram or Ternary Plot in Geochemistry?
A ternary diagram, also known as a ternary plot or triangle plot, is a three-variable graph used to represent the composition of a mixture or system composed of three components. These ternary diagrams are typically displayed as equilateral triangles, with each apex representing one of the three components. The interior of the triangle represents all possible combinations of these components, and ...

Geotechnical Characterization for Bridge and Tunnel Construction - Case Study
Motivation Two major civil infrastructure projects in the United Kingdom required accurate and precise mapping of subsurface porosity and permeability to ensure that underlying sediment formations were suitable for the intended construction. In the city of Ipswich, a new crossing over the River Orwell faced engineering risks associated with unmapped soft sediments and zones of dissolution in ...

Piper Diagrams in Chemistry Water Analysis
Arthur M. Piper introduced the Piper diagram in 1994. It is used for studying water chemistry and quality. The Piper diagram helps in the segregation of analytical data necessary for determining the sources of the constituents dissolved in water. The applicability of the procedure is possible due to natural water having anions and cations in chemical equilibrium. The most abundant cations in ...

Porosity and permeability values: Filling the gaps with NMR (Nuclear Magnetic Resonance)
Balazs Rigler of Fugro discusses the group’s efforts to improve the efficiency and accuracy of hydrological analyses for nearshore and onshore foundation engineering in soft geology. The hydrological properties of sandy, chalk or clay geology are of interest to designers of foundations, tunnels and other underground structures. Without a robust understanding of porosity and permeability it ...

Assessing the transport and fate of MTBE
Untitled Document Abstract The ether oxygenates MTBE and TAME have been used in petroleum fuel formulations in the UK since the mid-1980s and have led to contamination of major aquifers with these chemicals, including the Chalk aquifer of southern England. An assessment is made of the controls on the fate of MTBE and BTEX compounds at a contaminated site on the Chalk aquifer, ...

Halogenated Volatile Organic Compounds
Sites where halogenated VOCs may be found include burn pits, chemical manufacturing plants or disposal areas, contaminated marine sediments, disposal wells and leach fields, electroplating/metal finishing shops, firefighting training areas, hangars/aircraft maintenance areas, landfills and burial pits, leaking collection and system sanitary lines, leaking storage tanks, radioactive/mixed waste ...

Comparison of Eight Innovative Site Characterization Tools Used to Investigate
Environmental assessment of contaminated sites often requires delineation of the pathways of contaminant migration. Often, the pathways are strongly affected by the subsurface geology. At Vandenberg AFB in California, an accidental release of gasoline containing MTBE occurred at a base gasoline station in 1994. Dissolution of the gasoline into groundwater has created a dissolved MTBE plume at ...

Properties and Behavior of Nonhalogenated VOC`s
An important consideration when evaluating a remedy is whether the compound is nonhalogenated or halogenated. A nonhalogenated compound is one which does not have a halogen (e.g., fluorine, chlorine, bromine, or iodine) attached to it. The vendor of the technology being evaluated must be informed whether the compounds to be treated are nonhalogenated or halogenated. In most instances, the vendor ...

Properties and Behavior of Fuels
Fuel contaminants are generally nonhalogenated. Information presented for nonhalogenated VOCs and nonhalogenated SVOCs may also be appropriate for many of the fuel contaminants presented in this subsection. Contamination by fuel contaminants in the unsaturated zone exists in four phases: vapor in the pore spaces; sorbed to subsurface solids; dissolved in water; or as NAPL. The nature and extent ...

Properties and Behavior of Halogenated VOCs
An important consideration when evaluating a remedy is whether the compound is halogenated or nonhalogenated. A halogenated compound is one onto which a halogen (e.g., fluorine, chlorine, bromine, or iodine) has been attached. The nature of the halogen bond and the halogen itself can significantly affect performance of a technology or require more extensive treatment than for nonhalogenated ...

Properties and Behavior of Halogenated SVOCs
An important consideration when evaluating a remedy is whether the compound is halogenated or nonhalogenated. A halogenated compound is one onto which a halogen ion(e.g., fluorine, chlorine, bromine, or iodine) has been attached. The nature of the halogen bond and the halogen itself can significantly affect performance of a technology or require more extensive treatment than for nonhalogenated ...

Properties and Behavior of Nonhalogenated SVOCs
Subsurface contamination by nonhalogenated SVOCs potentially exists in four phases: Gaseous phase: contaminants present as vapors in saturated zone. Solid phase: contaminants adsorbed or partitioned onto the soil or aquifer material in both saturated and unsaturated zones. Aqueous phase: contaminants dissolved into pore water according to their solubility in both saturated and unsaturated ...
