Amanda, At Fermi we would use gamma spec (1-liter) and count to environmental LLDs. Two further questions you should consider: How will you ensure that you have taken a representative sample (set)? How will you quantify tritium activity? IMHO, the first question is always applicable the second may be optional, depending on specifics of the soil in question. EPA SW846 and MARSSIM can guide you in the creation of a sample plan that will ensure that you have properly surveyed the soil for free-release.
