Idaho Admin. Code r. 02.03.01.010 - DEFINITIONS
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)
