Vapor Intrusion
Vapor Intrusion occurs when harmful soil contamination changes phase from liquid to vapor underground and moves upward through geologic layers and building foundations, accumulating within indoor air.

Time Stratigraphic Unit Definition A Time Stratigraphic Unit, or a Chronostratigraphic Unit, is a rock unit that is characterized by geological formations, during a specific period of time. This serves as a reference for all rocks formed during the same time period.

Engineering Geology or Geological Engineering Engineering Geology: Engineering geology is also referred to as “geological engineering,” and is a branch of geology that relates to the study of earth materials and processes, that are juxtaposed to proposed structures such as buildings, retaining walls, dams, roads, pipelines, and more. Whereby geologists assess any potential levels of…

Can You Retest a Methane Test of Soil? Is it worthwhile to get a retest methane test of soil: Generally Not. Sometimes a methane test will show high results of the hazardous soil gas on a property.

Dry Cleaner Soil Contamination Dry cleaner soil contamination issues are no mystery to commercial property owners and investors. Even when landlords trust their dry cleaning tenants to run a clean shop, the process remains stressful. For instance, soil contamination cleanup can cost hundreds of thousands of dollars. Additionally, time and development opportunities may be impacted….

Seismic Risk Definition Seismic risk is the probability that a subject site will be adversely affected by any seismic hazard, such as an earthquake. Seismic risk tends to increase in areas that are more earthquake-prone and vulnerable to damage. And vulnerability refers to the potential impact on people, as well as properties. For instance, places…

Body-Wave Magnitude Body-Wave Magnitude: A method for determining earthquake size from the amplitude of body waves. The body-wave magnitude focuses on P-waves and S-waves, which travel faster through the Earth’s crust and mantle.
