Remediation is the word environmental cleanup companies often use. Essentially just removing the top ten or fifteen feet of soil and saying "all clean". Interestingly, all a company needs to do to demonstrate that an area is clean is provide x number of groundwater samples that show clean. What officials ignore is that there might be forty or fifty not-clean samples that are ignored in favour of the, say, five clear samples required. Dirty stuff.
