Long-term River Monitoring
Alton Natural Gas Storage has an ongoing monitoring program that is the most extensive study ever conducted of the Shubenacadie River estuary.
The monitoring, which began in 2008, has resulted in 10 years of scientific study on the water and in the lab by researchers from Dalhousie University's Faculty of Agriculture.
Detailed information has been gathered on the species (types of fish) present in the Shubenacadie River estuary at the Alton Gas site and their numbers with respect to salinity as the tide comes in and goes out. The program also gathers data on physical conditions including salinity, water temperature and oxygen concentration. Importantly, researchers have identified the link between Striped bass spawning in the spring and water temperature.

The monitoring findings to date have helped Alton develop measures to protect the environment and the integrity of the ecosystem now and in the future. These measures include:
- A gabion wall for water intake during cavern construction. The gabion wall will minimize the chance of fish and small organisms passing through
- An observation well behind the gabion wall for additional monitoring
- Ensuring we have the ability to control and immediately stop brining to mitigate any impact to the ecosystem of the Shubenacadie River estuary
- Working with the Department of Fisheries and Oceans and Environment Canada to develop a detailed monitoring system for the operational phases of the project
