Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.
Exfiltration means any unauthorized release of data from within an information system. This includes copying the data through covert network channels or the copying of data to unauthorized media.
Filtration means a process for removing particulate matter from water by passage through porous media.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Infiltrative surface means designated interface where effluent moves from distribution media or a distribution product into treatment media or original soil. In standard trench or bed systems this will be the interface of the distribution media or product and in-situ soil. Two separate infiltrative surfaces will exist in a mound system and an unlined sand filter, one at the interface of the distribution media and fill sand, the other at the interface of the fill sand and in-situ soil.
Injection means the pressurized placement of septage waste below the surface of soil.
Geothermal fluid means water in any form at temperatures greater than 120
Injection Point means the Electric Interconnection Point.
Infiltration rate means the rate of water entry into the soil expressed as a depth of water per unit of time (e.g., inches per hour).
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Potable means water suitable for drinking by the public.
Plasma arc incinerator means any enclosed device using a high intensity electrical discharge or arc as a source of heat followed by an afterburner using controlled flame combustion and which is not listed as an industrial furnace.
Open type traction battery means a type of battery requiring filling with liquid and generating hydrogen gas that is released to the atmosphere.
Underground injection means the subsurface emplacement of fluids through a bored, drilled or driven well; or through a dug well, where the depth of the dug well is greater than the largest surface dimension. (See also “injection well”.)
Irradiation means the exposure of a living being or matter to ionizing radiation.
Brine means all saline geological formation water resulting from, obtained from, or produced in connection with exploration, drilling, well stimulation, production of oil or gas, or plugging of a well.
Injection tool means a device used for controlled subsurface injection of radioactive tracer material.
borehole means a hole sunk into the earth for the purpose of locating, abstracting or using subterranean water and includes a spring;
Hydraulic fracturing means the fracturing of underground rock formations, including shale and non-shale formations, by manmade fluid-driven techniques for the purpose of stimulating oil, natural gas, or other subsurface hydrocarbon production.
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
PAD means a Preauthorized Debit.
Surface water means all water which is open to the atmosphere and subject to surface runoff.
Uppermost aquifer means the geologic formation nearest the natural ground surface that is an aquifer, as well as lower aquifers that are hydraulically interconnected with this aquifer within the facility's property boundary.
Filter means material placed in the useful beam to preferentially absorb selected radiations.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
