Interstitial water definition
Interstitial water means water contained in the inter- stices or voids of soil or rock in the dredged material.
Interstitial water means water in spaces between solid earth particles; and
Sediment means solid material, mineral or organic, that is in suspension, is being transported, or has been moved from its site of origin by air, water or gravity as a product of erosion.
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.
Sedimentation means a process for removal of solids before filtration by gravity or separation.
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.
