The Nova Scotia Groundwater Observation Well Network was established in 1965. It currently includes 38 active observation wells located across the province. The locations of the wells are shown in Map 1 (PDF: 663k). The network is used to:
- monitor groundwater levels
- monitor groundwater quality
- evaluate the impact of human activities on groundwater
- evaluate long-term trends associated with issues such as climate change.
The observation well network is equipped with electronic dataloggers and telemetric units that record water levels every hour and transmit the data to a central computer. The wells are visited approximately every six months for field verification and water samples are collected periodically to test groundwater chemistry.
Results are also available for inactive wells that are no longer being monitored.
