The town of Cobourg will be installing groundwater monitoring wells on Friday on George Street and Alice Street.
Groundwater Monitoring wells will assist with evaluating the readiness of the Tannery Lands for re-development.
This monitoring has been ongoing for 10 years and older wells are in need of replacement.
Two new ground water wells and soil probes are being installed to further delineate and monitor soil and groundwater trends.
The work is slated to be complete on Friday and the public is advised to obey traffic signage and flag persons on site.
