Standardized, or systematic, sub-surface testing for Archaeological Impact Assessments (AIAs) has been common practice in CRM methodology since the 1970s, when an increase in land development projects occurred throughout North America. Traditionally, test pits are hand dug with shovels and processed with bipedal screens; however, innovations out of an industry partnership between Colbr Consulting Inc. and the Government of New Brunswick have seen this methodological standard take massive leaps forward in utility, efficiency, accuracy and preference by developers.
Enhanced testing, or mechanical sub-surface testing, methods for AIAs increases many aspects of archaeological survey, including: the number of areas suitable for testing, the depth to which systematic testing can occur, and testing efficacy in wet sites. Furthermore, it replaces monitoring in many cases, reduces the time required to test large scale projects, and reduces technician attrition and fatigue. In addition, it increases the amount of site being sampled as well as the confidence interval, and increases artifact recovery rates per test pit. Lastly, it ensures replicability in every test pit excavated. Mechanical testing for AIAs should be considered an ‘Enhanced Testing’ method as it is more efficient, more evolved, more economical and just as ethical as traditional shovel testing.
