72 hour pump testing - Mill Bay, Shawnigan Lake area
We have been doing extensive 72 hour pump testing in the Mill Bay, Shawnigan Lake area, these well tests are are used to determine the availability of a adequate water source for a proposed development. We pump these wells at a flow rate determined by a Professional Groundwater Hydrologist for 72 hours measuring the water level as the water level drops, these measuements are recorded on a data sheet the plots this drawdown and will tell the Hydrologist the safe pumping rate and long term yield of the well.
After the 72 hours of pumping the pump is shut down and we then measure the water coming back up the well bore, this is called recovery. These tests are valuable in protecting our groundwater resource which is being threatened with over use.
