Alum Application – Day 2

Today the Heart Lake alum application project was completed on schedule! As planned, a dose of over 16,000 gallons of alum and over 8,000 gallons of sodium aluminate was applied in a precise, uniform, and most importantly… safe manner. There is no greater measure of success than safety and Heart Lake marks HAB’s 70th project…

Alum Application – Day 1

HAB had a productive day and applied 8,400 gallons of alum and 4,200 gallons of sodium aluminate to the lake.  HAB’s application equipment is well-suited for the precision required for the Heart Lake project.  Any gaps in coverage would allow for phosphorus from untreated lakebed sediments to leach into the overlying water column and stimulate…

Mobilization Day

HAB spent the first day of the 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. We are excited to get the application started in…
