Well characteristics
Across the wells Terracon has drilled, the median depth is 24 ft (middle half 17 ft–30 ft), median tested yield 1 gpm, and median static water level 13 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
Original drilling logs
Recent well logs filed by Terracon, straight from the public MBMG record:
"Records span 1999–2017" refers to the earliest and latest well logs attributed to this company in the MBMG database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
