Well characteristics

Across the wells Dupage Pump has drilled, the median depth is 175 ft (middle half 145 ft–205 ft), median tested yield 10 gpm, and median static water level — below ground surface. These summarize the company's own filed logs, not a marketing claim.

Original drilling logs

Recent well logs filed by Dupage Pump, straight from the public ISGS record:

"Records span 1900–1981" refers to the earliest and latest well logs attributed to this company in the ISGS database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
