Words defined in SDCL
	 34A-2-2 have the same meaning

  saturated permeable material to yield economical quantities of water to wells
  and springs;
(2) "Ambient," the
  constituents or parameters and the concentration or measurements which describe
  water quality prior to a subsurface discharge;
(3) "Board," the South Dakota Board of Water
  Management;
(4) "Compliance
  monitoring point," a well or wells located at the appropriate edge of the
  perimeter of operational pollution which is determined to be the earliest point
  of detection of a violation of a groundwater discharge plan;
(5) "EPA," the United States Environmental
  Protection Agency;
(6)
  "Contaminant," any physical, chemical, biological, or radiological substance or
  matter in water which is potentially harmful to human health;
(7) "Gradient," the change in total head per
  unit of distance;
(8)
  "Groundwater," water below the land surface that is in the zone of
  saturation;
(9) "Groundwater
  table," the upper surface of the zone of saturation of an unconfined
  aquifer;
(10) "Effluent," the
  discharge of partially or completely treated or untreated liquid
  waste;
(11) "Leachate," water that
  has percolated through solid waste or soils containing dissolved soluble
  substances and certain amounts of these substances in solution;
(12) "NPDES," the National Pollutant
  Discharge elimination system;
(13)
  "Owner and operator," person legally responsible for a facility subject to the
  provisions of this chapter;
(14)
  "Parameter," any physical, chemical, biological, or radiological constituent or
  characteristic of the groundwater, such as temperature, pH, and groundwater
  level;
(15) "Permitted allowable
  limit," the maximum groundwater contaminant concentration allowed at the
  compliance monitoring point as specified in the groundwater discharge
  permit;
(16) "Perimeter of
  operational pollution," "POP," a three-dimensional section of geologic
  materials surrounding the point of application of discharge within which
  groundwater quality degradation is permitted to occur;
(17) "Point of application," the outermost
  limit at which effluent or leachate has been stored, applied, disposed of, or
  discharged; for a diked facility, the outermost edge of the dikes;
(18) "Pollutant," dredged spoil, solid waste,
  incinerator residue, sewage, sewage sludge, garbage, trash, chemical waste,
  biological material, radioactive material, heat, wrecked or discarded
  equipment, rock, sand, or any industrial, municipal, or agricultural waste
  discharged into waters of the state;
(19) "Pollution," such contamination or other
  alteration of the physical, chemical, or biological properties of any waters of
  the state that exceeds that permitted by state effluent or water quality
  standards, or both, including change in temperature, taste, color, turbidity,
  or odor of the waters, or such discharge of any liquid, gaseous, solid,
  radioactive, or other substance into any waters of the state as will or is
  likely to create a nuisance or render such waters harmful, detrimental, or
  injurious to public health, safety, or welfare; or to domestic, commercial,
  industrial, agricultural, recreational, or other legitimate beneficial uses; or
  to livestock, wild animals, birds, fish, or other aquatic life;
(20) "Procedurally complete," an application
  for a groundwater discharge plan that contains all information necessary to
  fully address §
									74:54:02:06;
(21) "Radius of influence," the radial
  distance from the center of a well bore to the point where there is no lowering
  of the water table or potentiometric surface because of pumping of the well;
  the edge of the cone of depression;
(22) "Secretary," the secretary of the
  Department of Environment and Natural Resources or a representative designated
  to act for the secretary;
(23)
  "Vadose zone," the zone containing water under pressure less than that of the
  atmosphere, including soil water, intermediate vadose water, and capillary
  water, limited above by the land surface and below by the surface of the zone
  of saturation or the water table;
(24) "Well," an artificial excavation or
  opening in the ground made by digging, boring, drilling, jetting, or another
  artificial method often walled or cased to prevent the sides from caving in,
  whose depth is greater than the largest surface dimension.
