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.

Feldspars Feldspars: In the field of geology, and the branch of mineralogy, feldspars are a mineral group, that is the most common amongst the earth’s crust. In fact, there are two types of feldspars: plagioclase feldspar and orthoclase feldspar.

Diagenesis Diagenesis: In geology, diagenesis refers to the physical and chemical changes of a sedimentary formation when compaction and lithification occur over time.

Environmental Compliance Definition Environmental Compliance: Environmental Compliance is the action and fact by which an individual or business complies with every applicable environmental law, standard, code, policy, and regulation. Environmental Compliance is required for any entity to become a qualifying environmentally sustainable organization and is a priority for public health matters and business ethics. Essentially,…

Permeability “Permeability” in engineering geology and geotechnical engineering refers to the property of a soil sample (or porous rock) which relates to transmitting a fluid within. Permeability measures the relative case of flow under unequal pressure. Permeability is calculated using Darcy’s Law.

Impervious Membrane in Methane Mitigation Impervious Membrane: In accordance with the Los Angeles Department of Building and Safety (LADBS) Methane Code, Ordinance Number 175790, an impervious membrane is a continuous methane gas barrier. It is a crucial part of the methane mitigation process and underlies a building to impede the vapor intrusion of methane soil gas….
