Additional file 7: Supplementary Figure 1. Approval from the MBTA. We received the letter of approval from MBTA, by way of the General Manager’s Office, to carry out the study and confirmed the detailed sampling plans with the MBTA prior to any public work. Their assistance and input were invaluable both for study design and for safe execution of sample collection, and the letter includes the initial information from Evan Rowe approving the work.
