Wetland Terms – I-J-k
- immiscible: incapable of blending or mixing. In part of the process of converting untreated water into drinkable water, the water must be held undisturbed for a period of time to allow the immiscible pollutants to separate from the water.
- impervious: not capable of being passed through, damaged, or disturbed. (Water is not able to flow through impervious surfaces, such as asphalt roads and concrete sidewalks.)
- incinerator: an apparatus used for burning waste at very high temperatures; a furnace.
- independent variable: a manipulated variable; a factor or condition that changes naturally or is intentionally manipulated by the investigator to observe the effect.
- indicator: any of a variety of substances used to demonstrate the presence, absence, or concentration of a substance.
- industrial: related to the commercial production of goods.
inorganic: compounds derived from non-living things that do not contain carbon.
- interdependent: organisms that need each other for survival.
- invasive species: organisms that spread, encroach upon, and take over the habitat of native species.
- invertebrates: animals that do not have a backbone.
- jackson turbidity unit (JTU): a unit of measure for turbidity (derived from the original "Jackson Tube"). Turbidity is measured by determining the amount of light that is reflected off particles suspended in water.
- japanese honeysuckle: Lonicera japonica; an exotic invasive plant, originally from East Asia, that grows at the wood's edge.
- kudzu: Pueraria thunbergiana; an exotic invasive bean vine, originally from China and Japan.
