Background Data

Five background air samples were collected over two weeks in October 2016. This background air data-collected before any intrusive, below-ground activities began-was used to quantify the typical existing levels of any dust and volatile organic compounds already in the air. It also will be used by the agencies to adjust action and alert levels in the air monitoring plan. Action levels, which are set above the background levels, define the steps the contractor will take to meet the plan's air requirements.
