Supply stress
Springboro's entire supply is a single shallow aquifer, and the city's own 2025 CCR says so plainly: the buried valley aquifer it draws from is 'highly susceptible to surface contamination.' Ohio's 2001 source water assessment rated susceptibility high because the aquifer sits less than five feet below ground surface with significant…
