A sampling batch, as defined by the United States Environmental Protection Agency via its SEDD Specification Version 5.2, is a "sampler-defined identifier that is used to link multiple samples collected together. Operationally, this batch associates a field blank with a group of samples." The EPA adds that "this value is currently often not known to the laboratory. It might be merged with laboratory data by a validator."
