IST is an industry leader in applying innovative approaches to subsurface remediation, and has implemented many successful remediation projects in the United States and Europe. We have applied a wide range of remediation technologies to a variety of sites and contaminants and have successfully brought numerous sites to closure through active remediation. IST has also avoided active remediation at many sites through risk assessment, regulatory negotiations, and analysis of monitored natural attenuation alternatives.

IST has designed, installed, and operated successful remediation systems at:

•  Oil-bulk Storage Terminals
•  Refineries
•  Chemical Plants
•  Wood Products Manufacturing Facilities
•  Former Coal-Gas Plants
•  Grease Plants
•  Landfills
•  Retail Gasoline Facilities

These sites were impacted by a wide range of contaminants:

•  Petroleum
•  Coal Tars
•  Chlorinated and Other Solvents
•  Black Liquor
•  Caustics
•  Metals
•  Pesticides
•  Asbestos

IST has either developed or used most of the remediation technologies in existence, and we have brought several sites to closure by integrating in situ and ex situ technologies from the list on the left of this page. IST personnel have authored numerous textbooks on remediation techniques and principles, published widely in the technical literature, and served as peer reviewers for several respected technical publications.

IST is an internationally recognized leader in bioremediation, with numerous staff publications documenting experience with many in situ and ex situ bioremediation systems that we have installed around the world. Additionally, IST staff have repeatedly chaired international conferences, symposia, and discussion forums in the areas of bioremediation and remediation technology. IST’s remediation experience also includes many demonstrations of natural attenuation and monitored natural attenuation of organic compounds and arsenic.

IST’s remediation philosophy is to help clients achieve site cleanup goals as efficiently and quickly as possible. Well conceived pilot testing, system design and installation, system run time maximization, and system optimization achieve this. Quantifying the progress of cleanup (contaminant mass removal and concentration reduction) provides evidence to petition for site closure. This quantification often paves the way for the approval of natural attenuation tracking or granting a status of no further action at a site.
