Groundwater Project
This study involves updating our existing well inventory to:
1) add new wells that have been drilled
2) correct some spatial errors
3) put the data into a format that can be used in GIS mapping and analysis.
The well survey data will be incorporated into a Groundwater Vulnerability Assessment of Chebeague Island which will assess the carrying capacity of the island’s aquifer, evaluate potential impacts of continued development and assess the potential impacts of climate change including the risk of saltwater intrusion. The results of this study will be used to inform the development land use practices that take groundwater protection and climate resiliency into account.
1
Well Study
Tell us about your well! Well survey forms were mailed to every homeowner and were available at the town office, library, and online for people to fill out.
2
Well Sampling
This summer the CCAT members and community volunteers are conducting an island wide well sampling program.
3
Water Testing
Wells will be analyzed for specific conductance, bacteria, and sodium chloride to evaluate the impacts of development and saltwater intrusion.
End Result
The results of these surveys and tests will be used to help us assess the vulnerability of Chebeague's groundwater, the capacity of the island's aquifer, and evaluate potential impacts/threats to the water supply. This could include further land development, climate change impacts, etc.
