Current through August 31, 2023
The Idaho Department of Agriculture adopts the definitions set
				forth in Section
				22-3401, Idaho Code, and the
				following definitions: (3-31-22)
01.
Aquifer
. A geological unit of permeable saturated material capable
			 of yielding economically significant quantities of water to wells and springs.
			 (3-31-22)
02.
Beneficial
			 Uses
. Current or future uses of ground water supplies including, but not
			 limited to domestic, industrial, agricultural, aquacultural, and mining.
			 (3-31-22)
03.
Best Management
			 Practice
. A practice or combination of practices determined to be the
			 most effective and practical means of preventing or reducing pesticide
			 contamination to ground water and interconnected surface water from nonpoint
			 and point sources to achieve water quality goals and protect the beneficial
			 uses of the water. (3-31-22)
04.
Constituent
. Any chemical, ion, radionuclide, synthetic organic
			 compound, microorganism, waste or other substance occurring in ground water.
			 (3-31-22)
05.
Contaminant
. Any chemical, ion, radionuclide, synthetic organic
			 compound, microorganism, waste or other substance which does not occur
			 naturally in ground water or which naturally occurs at a lower concentration.
			 (3-31-22)
06.
Contamination
. The direct or indirect introduction into ground
			 water of any contaminant caused in whole or in part by human activities.
			 (3-31-22)
07.
Ground
			 Water
. Any water of the state which occurs beneath the surface of the
			 earth in a saturated geological formation of rock or soil. (3-31-22)
08.
Health Advisory Level
.
			 Guidance for the maximum allowable or acceptable daily concentration of a
			 pesticide in drinking water in the absence of or prior to a MCL being set.
			 (3-31-22)
09.
Maximum
			 Contaminant Level
. Maximum allowable or acceptable daily concentration
			 of a pesticide in drinking water that may be consumed over a lifetime.
			 (3-31-22)
10.
Pesticide
			 Management Standard
. The United States Department of Agriculture Natural
			 Resource Conservation Service Conservation Practice Standard, Idaho Pesticide
			 Management Code 595, or the Idaho Agricultural Pollution Abatement Plan --
			 Pesticide Management Standard Component Practice. (3-31-22)
11.
Pesticide Use
. The mixing,
			 application, handling, transport, storage, display, distribution, and disposal
			 of pesticides and their containers. (3-31-22)
12.
Projected Future Beneficial
			 Uses
. Various uses of ground water, such as drinking water, aquaculture,
			 industrial, mining or agriculture, that are practical and achievable in the
			 future based on hydrogeologic conditions, water quality, future land use
			 activities and social/economic considerations. (3-31-22)
13.
Reference Dose
. Allowable or
			 acceptable dose of a pesticide in terms of mg pesticide/kg body weight that can
			 be ingested in one day (acute reference dose) or on a daily basis over a
			 lifetime (chronic reference dose). (3-31-22)
14.
Reference Point
. Numerical
			 indicators of the toxicity of a substance based on test data and other reliable
			 health effects information. (3-31-22)
15.
Susceptibility
. A method of
			 describing the flow of water to, and through, the ground water resource based
			 on physical factors such as hydraulic conductivity, porosity, hydraulic
			 gradients, recharge, interactions with surface water, and transport through the
			 unsaturated zone without considering specific natural or anthropogenic sources
			 of contamination. (3-31-22)
16.
Vulnerability
. Ground water characterized by a potential for
			 contaminants to enter and be transported within the flow system. Determinations
			 of ground water vulnerability will include consideration of land use practices
			 and aquifer characteristics. (3-31-22)
