Following the Sampling Instructions, all samples should be submitted in the proper conditions, accompanied by written instructions on a properly completed Chain of Custody form with the following minimum information:

  • Company name, address, phone number and person receiving the report.
  • Type of samples.
  • Date and time of sampling.
  • Name of sampler.
  • Analyses needed on each sample.
  • Project name or sample site.
