  • Description: •Pumping wells displayed alternating temperature signals between pump-on and -off.•PITSs were highest in summer and winter but lowest in spring and fall.•Pumping lowered the temperature of produced water in winter but raised it in summer.•Heat transfer velocity was higher for pumping period than that for recovery period.•Thermal analysis reveals that the temperature of pumped water can trace source water. Moving water can transport temperature signals of surface water into groundwater or vice-versa. We analyzed the temperature signals in the atmosphere, river, and pumped water to elucidate source water contributions to the pumping wells from the ambient groundwater and the river. Temperature fluctuations in response to high-frequency intermittent pumping were observed from February 2014 to August 2016 in 14 wells within three shallow unconfined alluvial aquifers along the Ohio River. The groundwater temperature observed in pumping wells displayed two alternating...
