Despite this effort. traces of contamination remained visible in the sidewalls of the trench. Note black stains in the area beyond the excavator bucket. Excavations completed by the end of the day had created conditions that required additional earth-moving along the tops of the trench banks to allow for step-backs necessary to protect against sidewall collapse. Such earth-moving is likely to require some hours, and activity within the trench is likely to be postponed until safe conditions can be reestablished. (May 28, 2015)
