Rhus aromatica, commonly known as fragrant sumac, aromatic sumac, lemon sumac, polecat bush, polecat sumac, or simply sumac, [1] [2] is a deciduous shrub in the family Anacardiaceae native to North America. [3] It is native to southern and eastern Canada, most of the contiguous United States, and Mexico. [2] [4]
Sumac or sumach [a] (/ ˈ s uː m æ k, ˈ ʃ uː-/ S(H)OO-mak, UK also / ˈ sj uː-/)—not to be confused with poison sumac—is any of the roughly 35 species of flowering plants in the genus Rhus (and related genera) of the cashew and mango tree family, Anacardiaceae.
Rhus trilobata closely resembles other members of the genus that have leaves with three "leaflets" ("trifoliate" leaves). These include Rhus aromatica, native to eastern North America, and western poison-oak. The shape of the leaflets and the habit of the shrub make this species, like some other Rhus, resemble small-leafed oaks .
Wetlands help maintain the level of the water table and exert control on the hydraulic head. [ 5 ] [ 6 ] This provides force for groundwater recharge and discharge to other waters as well. The extent of groundwater recharge by a wetland is dependent upon soil , vegetation , site, perimeter to volume ratio, and water table gradient.
Groundwater models are used in various water management plans for urban areas. As the computations in mathematical groundwater models are based on groundwater flow equations , which are differential equations that can often be solved only by approximate methods using a numerical analysis , these models are also called mathematical, numerical ...
Arsenic contamination of ground water is found in many countries throughout the world, including the US. [2] The World Health Organization recommends limiting arsenic concentrations in water to 10 μg/L, although this is often an unattainable goal for many problem areas due to the difficult nature of removing arsenic from water sources.

Soil vapor extraction (SVE) is a physical treatment process for in situ remediation of volatile contaminants in vadose zone (unsaturated) soils (EPA, 2012). SVE (also referred to as in situ soil venting or vacuum extraction) is based on mass transfer of contaminant from the solid (sorbed) and liquid (aqueous or non-aqueous) phases into the gas phase, with subsequent collection of the gas phase ...
