  "term": "Infiltration",
  "field": "Environment",
  "definition": "1. The flow of a fluid into a substance through pores or small openings. Commonly used to in hydrology to denote the flow of water into soil material.\n\n2. The gradual flow or movement of water into and through (to percolate or pass through) the pores of the soil.\n\n3. The penetration of water from the soil into sewer or other pipes through defective joints, connections or manhole walls.\n\n4. Unintended air leakage, or infiltration, occurs when outside air enters a house through cracks and openings around doors, windows, and ducts. Properly sealing these cracks and openings in a home can significantly reduce heating and cooling costs, improve building durability, and help prevent pests from entering your home.\n\n5. The process whereby water enters a sewer system and service connections underground through such means as, but not limited to, defective pipes, pipe joints, connections, or manhole walls. Infiltration does not include, and is distinguished from inflow.\n\n6. The movement of water through the ground surface into the unsaturated zone.\n\n7. The penetration of water through the ground surface into sub-surface soil or the penetration of water from the soil into sewer or other pipes through defective joints, connections, or manhole walls.\n\n8. The technique of applying large volumes of waste water to land to penetrate the surface and percolate through the underlying soil.\n\n9. Air leakage through random cracks, interstices, and other unintentional openings in the building envelope.\n\n10. Air leakage inward through cracks and interstices and through ceilings, floors, and walls of a space or building.\n\n11. The flow of a fluid into a substance through pores or small openings. Commonly used in hydrology to denote the flow of water into soil material.\n\n12. Flow of water from the land surface into the subsurface.\n\n13. Movement of water, typically downward, into soil or porous rock.\n\n14. Flow of a fluid into a substance through pores or small openings. Commonly used to in hydrology to denote the flow of water into soil material.\n\n15. The downward movement of water through a soil in response to gravity and capillary suction.\n\n16. The movement of water from the land surface into the soil.",
