Well characteristics

Across the wells IL State Geological Survey has drilled, the median depth is 177 ft (middle half 24 ft–300 ft), median tested yield 12 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 IL State Geological Survey, straight from the public ISGS record:

"Records span 1974–2018" 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.
