Not going to go into detail however, as someone who has been cleaning up contaminated sites for 20 years...the cost to cleanup contamination such as this will definitely be higher as time goes on. There is no magic potion that will bio-remediate the soils insitu in a timeframe of our lifetime (nor will one be found). Creosote, PAH's and heavy HC's do not break down easily, leaving very little options. One of the saving graces is that they are not as mobile and will not expand much over time. However, regulations and guildlines will get more stringent, thereby increasing volumes. Thinking there is going to some technology improvements that are going to be cheaper is wishful thinking. Best option is most likely source removal and risk assess the residuals.
