Sanexen performs this type of study to determine if a site has potentially been exposed to contamination, using the CSA standard protocol to do so. Such a study, essentially documentary, investigates the history of the activities that have occurred on the site and in the immediate surroundings. It highlights the elements or activities which present an environmental risk and defines those that may potentially have significant impact that would justify direct investigation.
