Across the wells Haz Tech Drilling Inc. has drilled, the median depth is 20 ft (middle half 19 ft–30 ft), median tested yield 10 gpm, and median static water level 14 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
Original drilling logs
Recent well logs filed by Haz Tech Drilling Inc., straight from the public MBMG record:
"Records span 1990–2026" 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.
