Well characteristics
Across the wells Boland Drilling has drilled, the median depth is 72 ft (middle half 25 ft–250 ft), median tested yield 25 gpm, and median static water level 36 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
Original drilling logs
Recent well logs filed by Boland Drilling, straight from the public MBMG record:
"Records span 1967–2026" 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.
