Mobilization

HAB spent the first day of the White Lake project preparing equipment for the application.  This included assembly of the barge’s application boom, programing the barge’s computerized dosing system, launching the barge into the lake, setting up on-shore storage tanks and confirming the delivery plan for the alum and buffer.  A small restricted work area…

Alum Floc
