About this area's water

Did you know
- Gambier buys 100% of its drinking water from the City of Mount Vernon and only owns the pipes that distribute it, plus its landmark elevated water tower.
- Mount Vernon's own Source Water Assessment rates the shared Buried Valley Aquifer 'HIGH' susceptibility to contamination -- the water table sits less than 15 feet below ground.
- Gambier's stormwater utility charges by rooftop and driveway size rather than water use, and gives credits for rain gardens or detention basins.
- The village was founded by Bishop Philander Chase, who also founded Kenyon College, and incorporated in 1870.
