Right now the science and engineering, as far as I understand it, is looking at the analytical technologies to measure naphthenic acids. As the name implies, naphthenic acids are a group of acids. There's a lot of research going into developing analytical techniques that are sensitive enough to detect low concentrations of naphthenic acids, along with analytical techniques that can actually see the fingerprints of those naphthenic acids. This would allow us to say for sure whether there is seepage or not.
