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.
Many health departments require a percolation test ("perc" test) to establish the suitability of drain field soil to receive septic tank effluent. An engineer , soil scientist , or licensed designer may be required to work with the local governing agency to design a system that conforms to these criteria.
Tetrachloroethylene, also known as perchloroethylene [a] or under the systematic name tetrachloroethene, and abbreviations such as perc (or PERC), and PCE, is a chlorocarbon with the formula Cl 2 C=CCl 2. It is a non-flammable, stable, colorless and heavy liquid widely used for dry cleaning of fabrics.
Companies using perc in consumer products, such as stain removers, or in industrial processes have under three years to do away with the chemical, the Washington Post reports. Dry cleaners will ...

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),
