I haven't done site cleanup work for almost 30 years. I was involved in some of the very earliest work in that area; I was on the state technical review team for the work at Occidental Chemical in Lathrop, CA, which, along with Aerojet General in Rancho Cordova and Fairchild Semiconductor in south San Jose, were the first big remediation projects in California. About that time, while I was still working for the CA Health Department, I adapted the hollow stem auger split barrel sampling technique for doing subsurface investigations. For a long time that because the standard approach for sampling.My ex-brother in law invented the equipment used to remove contaminated soil out of the ground. I wonder if you know Chuck J ?

Most of the sites I was involved with we tried to not remove soil unless it was highly contaminated. In most cases, you create more hazards by bringing the materials to the surface and either managing them on the ground surface or putting them in trucks and hauling the material on the road.
