A fluid sampling apparatus is disclosed for withdrawing samples of groundwater or other fluids from a well or other monitoring site. The apparatus preferably includes pump means, conduit means and a wellhead assembly that are substantially permanently installed at such well or monitoring site and are thereby dedicated thereto in order to avoid or minimize cross-contamination of samples from site to site. The apparatus preferably also includes a removable and portable controller means adapted for easy and convenient transportation and connection to such dedicated fluid sampling components at various wells or monitoring sites.

Toxic and hazardous organic materials are photochemically and thermally changed into innocuous and environmentally acceptable products through the proper application of solar energy. The present invention is especially well-suited for the destruction of polychlorinated biphenyls (PCB's) which are resistant to conventional incineration The method and apparatus described herein are also capable of handling liquids, solids or vapors, with only minor operating modifications.
