Well characteristics
Across the wells Thumb Well Drilling Inc. TO has drilled, the median depth is 120 ft (middle half 100 ft–160 ft), median tested yield 15 gpm, and median static water level 17 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1989–2025" refers to the earliest and latest well logs attributed to this company in the EGLE database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
