Abstract:
A method for monitoring levels of soil chemicals following a remediation injection, comprising:providing a groundwater sample to an apparatus comprising a sample injection assembly operatively coupled to a controller, the injection assembly adapted to selectively provide one of at least two predetermined volumes of a fluid sample to a mixing assembly in response to signals received from the controller, the injection assembly including a multiport injection value and at least two sample loops, selecting one of the at least two predetermined volumes of the fluid sample, transferring the selected volume of the fluid sample to the mixing assembly in response to a signal from the controller, transferring a predetermined volume of dilution fluid to the mixing assembly, mixing the predetermined volumes of dilution fluid and fluid sample to create a first diluted fluid sample, performing a concentration measurement on the first diluted sample.
