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 ...
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 .
A slug test is in contrast to standard aquifer tests, which typically involve pumping a well at a constant flowrate, and monitoring the response of the aquifer in nearby monitoring wells. Often slug tests are performed instead of a constant rate test, because: time constraints (quick results, or results for a large number of wells, are needed),
Most commonly an aquifer test is conducted by pumping water from one well at a steady rate and for at least one day, while carefully measuring the water levels in the monitoring wells. When water is pumped from the pumping well the pressure in the aquifer that feeds that well declines.
