The Dulles Corridor Metrorail Project has begun a series of drillings in the Tysons Corner area to explore the condition of soil in future construction areas, including identifying any ground contaminants that might be present.
The drilling machine bores into the ground at predetermined locations along the planned Metrorail route. The Project team collects soil samples at regular depth intervals and sends the samples away to a laboratory for analysis.
This soil sampling is a critical part of preparing for construction, currently scheduled to begin in December 2006.
