Inorganic Compounds . Inorganic compounds can be detected through direct 

 sample collection and characterization techniques. Both field and laboratory 

 analytical techniques-such as in-situ active microwave (including ground 

 penetrating radar), electromagnetic (frequency and time domain), thermal IR, 

 and electromagnetic (high frequency) -are available. 



Buried Objects . Currently available techniques for the detection of buried

electromagnetic (Ferrous), sonar, active seismic, photographic, and 

 multi/hyper spectral. 



Heavy Metal Contamination . A number of techniques are available for direct 

 sample collection and characterization. These techniques include 

 photogrammetry, multi/hyper spectral, and active and passive microwave. 



THEORETICAL STRATEGIES FOR REMEDIATION 



If it is necessary to remediate a hazardous or radioactive waste site, the 

 first step would probably be to retrieve intact waste containers. The 

 Department is developing robotic retrieval techniques for use at its wa^te 

 management site at the Idaho National Engineering Laboratory. Technologies 

 developed and demonstrated there could be applicable to land disposed waste in 

 the Former Soviet Union. These technologies may be modified to address 

 retrieval from shallow bays. A commercially available mini -submarine is
