USAID contractors continue building the containment structure. The wall now stands at 7.3 meters in the southeast corner (see photos above and below).
Contractors are installing a very strong, thick plastic liner on the bottom of the structure to prevent any water from draining out or entering the treatment system once operational.
USAID contractors completed construction of the drying pad (see photo below). The drying pad is being used to safely dry and store wet soil and sediment until it is ready to be loaded into the pile containment structure. To date, approximately 3,200m3 of contaminated sediment from the southeastern wetland has been placed in the drying pad for dewatering before it is moved to the treatment pile. All drainage water from the drying pad is collected and tested prior to being discharged.
