Well characteristics
Across the wells Dept OF Transportation has drilled, the median depth is 41 ft (middle half 19 ft–60 ft), median tested yield 25 gpm, and median static water level 9 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
Original drilling logs
Recent well logs filed by Dept OF Transportation, straight from the public MBMG record:
"Records span 1956–2017" 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.
