Abstract
Subsurface contaminants are readily and inexpensively detected and measured by means of a test head positioned at the subsurface site and forming a protected test chamber for the liquids to be tested. The head encloses the end faces of fiber optic elements which carry radiation to the liquid sample from a test instrument located at the surface and which return radiation from the sample to the instrumentation. A connector positioned at the surface decouples the head from the instrumentation, so that the same instrumentation can service a larger number of test sites.
