The Arkell Spring Grounds is a high yielding bedrock aquifer that produces numerous fresh water springs along the Eramosa River north-east of the village of Arkell. The City of Guelph began using the springs for municipal water in 1903, and added four high capacity wells in 1963 and 1967. This is the main source of water for the city of Guelph.
