Contaminated

I am looking for information of companies and techniques in dealing with Soil Remediation for soil contaminated with Cr6+. The project is large in size and would be viewed as a 2 year timeline, with multiple locations which may require transportation of a mobile facility. The Cr6+ is in particle form, and we are looking to hear from individuals or companies that have dealt with such a situation and the method that they feel has worked best in the most effective manner in remediation of the soil, cost. and time.
