Plutonic Rock (Igneous) Definition The term “Plutonic” in the field of geology refers to an igneous rock, wherein the magma had originally cooled, solidified, and crystalized underground. A plutonic rock is generally coarsely crystalline (phaneritic) and is formed during a massive geologic intrusion of magma. In fact, outcropping (or daylighting) plutonic rocks are geologic features…

Total Petroleum Hydrocarbons (TPH) Total Petroleum Hydrocarbons (TPH): The term “Total Petroleum Hydrocarbons” represents the complete carbon chain of hydrocarbon compounds that originate from petroleum. In general there are three ranges of TPH: Gasoline Range Total Petroleum Hydrocarbons (TPH-g); Diesel Range Total Petroleum Hydrocarbons (TPH-d); and Oil Range Total Petroleum Hydrocarbons (TPH-o). Gasoline range TPH represents the…

Consistency The term “Consistency” in the fields of engineering geology and geotechnical engineering means the degree of adhesion between soil particles within a sample, that are observed to resist deformation or rupture.

Hydraulic Head Hydrualic Head: In the field of hydrogeology, hydrualic Head is a measure of the potential energy of a fluid at any given point in a hydraulic system. It explains the potential energy driving fluid flow by summing the elevation of the fluid and the pressure it exerts.

Bowser Underground Gasoline Storage Tank & Storage Outfit Sylvanus Freelove (S.F.) Bowser is credited with inventing the first gasoline pump and storage tank combination in 1885. Originally, he invented the pump to dispense kerosene, but as the popularity of gasoline increased with the rise of the automobile, so too did the application of the Bowser…

Environmental Questionnaire Sample & Example An environmental questionnaire is a preliminary task in the environmental due diligence process by lenders and other information-seekers. The questionnaire screens the environmental hazards of a property undergoing any transaction. It consolidates the known facts of a property upfront, for a basic level of contamination and health risk presumption. Typically,…
