Well characteristics
Across the wells Pioneer Technical Services Inc. has drilled, the median depth is 18 ft (middle half 15 ft–22 ft), median tested yield 20 gpm, and median static water level 7 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
Original drilling logs
Recent well logs filed by Pioneer Technical Services Inc., straight from the public MBMG record:
"Records span 1969–2026" 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.
