In June 1999, Atlantic Canada introduced new guidelines for the management of contaminated sites.  These new guidelines apply a risk based approach to sites. 

The program that these guidelines fall under is referred to as Risked-Based Corrective Action in Atlantic Canada (Atlantic RBCA).  The Atlantic RBCA program was developed out of the American Society for Testing and Materials Standard E-1739-95. As stated in the program documentation, “...the Atlantic RBCA is a tiered approach where increasing site-specific detail can be used to derive remedial criteria that are progressively more specific to the site and less reliant on generic assumptions”.  The program is comprised of three tiers.  A brief description of these three tiers is given below.

Tier I:  Site-specific data are analyzed and compared to generic screening levels established by Atlantic RBCA.

Tier II:  Site-specific standards are developed to assess the need for remedial action.  The site-specific standards are generated by using an analytical model and data collected through intrusive investigations at the site.

Tier III:  Site-specific standards are developed for complex sites to assess the need for remedial action.  The site-specific standards are generated by using complex contaminant fate and transport computer models in order to make an assessment of human health risks and/or ecological risks.

Fundy Engineering has undertaken the necessary training to offer client services in risk assessment.  We are experienced with the Atlantic RBCA guidelines and all of the software required to undertake these site investigations and assessments.
