Obtaining representative groundwater samples from the formations of concern is a critical goal of any groundwater sampling effort. Appropriately trained and qualified field personnel are necessary to properly collect groundwater samples in conjunction with a well planned sampling protocol. The sampling protocol should define the procedures used to accurately make field measurements, to purge and withdraw samples from the well, fill sample containers and collect blank and replicate samples. The scope of this guidance document is to provide general guidelines to follow when preparing site specific sampling plans for groundwater sampling. Sampling plans are made after a monitoring scheme has been carefully designed and wells have been installed and properly developed.
The following are a summary of recommended sampling procedures to consider when planning a sampling event:
