Well characteristics

Across the wells Hillman Drilling has drilled, the median depth is 80 ft (middle half 50 ft–140 ft), median tested yield 25 gpm, and median static water level 30 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

Original drilling logs

Recent well logs filed by Hillman Drilling, straight from the public MBMG record:

"Records span 1973–2012" 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.
