(18) “Ground water” means water of underground streams, channels, artesian basins, reservoirs, lakes, and other water under the surface of the earth, whether public or private, natural or artificial, which is contained within, flows through, or borders upon this state or any portion thereof, including those portions of the Atlantic Ocean over which the state has jurisdiction.
(19) “Individual water well” means any well constructed for the purpose of obtaining ground water to supply water appurtenant to a single-family dwelling and intended for domestic use, including, but not limited to, household purposes, farm livestock, or gardens.
(20) “Industrial well” means any well constructed for the purpose of withdrawing 100,000 gallons of ground water or less on any one day for processing or cooling water or for purposes other than drinking water.
(21) “Irrigation well” means any well constructed for the purpose of obtaining ground water to supply irrigation water for agriculture, silviculture, golf courses, fish farms, and land beautification, but excluding single-family irrigation of lawns or gardens.
(22) “Monitoring well” means any well for which the primary purpose is to collect data for hydrologic, geohydrologic, or ground water quality or quantity evaluations.
(23) “Nonpublic water well” means any well constructed as a source of water supply for a water system which provides piped water to the public for human consumption, if such system has less than 15 service connections or regularly serves less than 25 individuals, excluding individual water wells.
(24) “Person” means any individual, partnership, association, trust, firm, corporation, county, municipality, or other entity, including the state and the federal government.
