Well characteristics

Across the wells IL State Water Survey has drilled, the median depth is 36 ft (middle half 21 ft–101 ft), median tested yield 102 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 Water Survey, straight from the public ISGS record:

"Records span 1925–2003" 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.
