Age dating of petroleum impacted soil is generally based on a known degradation rate of refined petroleum products.When a tank is removed and a release is discovered (i.e., oil stained soils are observed in the tank excavation, corrosion holes noted in the tank and elevated field screened readings for petroleum are observed) it can be presumed that the release did not just occur. Corrosion of a tank shell to the point of break through can take many years to occur, the rate of corrosion is based on a variety of factors.
On Wednesday July 5 between - GMT we’ll be busy making things better.
You’ll still be able to search, browse and read our articles, but you won’t be able to register, edit your account, purchase content, or activate tokens or eprints during that period.
We specialize in organic and inorganic analyses of soil, water, product, and vapor samples using EPA- and state-approved testing methods.

Each isotope you choose needs two different colors of beads associated with it and the total of number of beads per bag will be 100 (this creates the simplest math, but you could use less beads and have them calculate percentages if necessary).
For instance, if you choose Carbon-14 as your isotope, you will need 2 different colors (like red will be Carbon-14 and blue is Nitrogen-14).
Ideally, you would have 4 bags per lab group, but depending on the limiting number of supplies you have, you can just make a minimum of 4 bags and rotate them between groups.
Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for carbon-14 measurements.
F&B offers passive diffusion bags to clients looking to minimize field labor costs associated with quarterly monitoring.
