  "definition": "1. The supply of fresh water found beneath the Earth's surface, usually in aquifers, which supply wells and springs. Because ground water is a major source of drinking water, there is growing concern over contamination from leaching agricultural or industrial pollutants or leaking underground storage tanks.\n\n2. Water found below the surface of the land, usually in porous rock formations. Ground water is the source of water found in wells and springs and is used frequently for drinking.\n\n3. The water that systems pump and treat from aquifers (natural reservoirs below the earth's surface).\n\n4. The water under the surface of the earth that is found within the pore spaces and cracks between the particles of soil, sand, gravel and bedrock.\n\n5. CERCLA and the NCP define ground water as \"water in a saturated zone or stratum beneath the surface or land or water\".\n\n6. The supply of fresh water found beneath the earth's surface, usually in aquifers, which supply wells and springs. Because ground water is a major source of drinking water, there is growing concern over contamination from leaching agricultural or industrial pollutants and leaking underground storage tanks.\n\n7. The supply of fresh water found beneath the Earth's surface usually in aquifers which is often used for supplying wells and springs. Because ground water is a major source of drinking water there is growing concern over areas where leaching agricultural or industrial pollutants or substances from leaking underground storage tanks are contaminating ground water.\n\n8. Water that occurs below the surface of the Earth, where it occupies spaces in soil or layers of rock. When rain falls to the ground, some of it sinks into the ground and becomes ground water.\n\n9. The supply of fresh water found beneath the Earth's surface, usually in aquifers, which supply wells and springs.\n\n10. The supply of fresh water found beneath the Earth's surface, usually in aquifers, which supply wells and springs. It provides a major source of drinking water.\n\n11. The supply of fresh water found beneath the earth's surface, usually in aquifers, which supply wells and springs. Because groundwater is a major source of drinking water, there is growing concern over contamination from leaching agricultural or industrial pollutants and leaking underground storage tanks.\n\n12. Water that flows or seeps downward and saturates soil or rock, supplying springs and wells. The upper surface of the saturate zone is called the water table.\n\n13. Water stored underground in rock crevices and in the pores of geologic materials that make up the Earth's crust.\n\n14. In hydrologic terms, water within the earth that supplies wells and springs; water in the zone of saturation where all openings in rocks and soil are filled, the upper surface of which forms the water table.\n\n15. Water below the land surface in the saturated zone.\n\n16. Water below the land surface in a zone of saturation. [40 CFR 258.2 (CFR 2013)] [40 CFR 260.10 (CFR 2013)][40 CFR 270.2 (CFR 2018)][40 CFR 191.12 (CFR 2018)][40 CFR 146.3 (CFR 2018)][40 CFR 144.3 (CFR 2018)]\n\n17. As defined by section 101(12) of CERCLA, means water in a saturated zone or stratum beneath the surface of land or water.\n\n18. Water that is stored under the earth's surface, in the cracks and spaces between particles of soil, sand and rock.\n\n19. The water contained in the pore spaces of saturated geologic media.\n\n20. Water that is below the land surface and in a saturated zone.\n\n21. Ground Water is the supply of freshwater found beneath the Earth’s surface, usually in aquifers, which supply wells and springs for drinking water. When the groundwater table intersects the Earth's surface, groundwater supplies source water for rivers, streams, and lakes.",
