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]
One classification uses two subgenera, Rhus (about 10 spp.) and Lobadium (about 25 spp.), while at the same time Cotinus, Duckera, Malosma, Metopium, Searsia and Toxicodendron segregated to create Rhus s.s.. Other genera that have been segregated include Actinocheita and Baronia. As defined, Rhus s.s. appears monophyletic by molecular phylogeny ...
A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. [1] The results of a percolation test are required to design a septic system properly.
Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [1]
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 .
Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry .
R. aromatica may refer to: Ravensara aromatica , the clove nutmeg, a plant species found in Madagascar Rhus aromatica , the fragrant sumac, a plant species native to Canada and the United States
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.
