Well characteristics

Across the wells Pat Oconnor has drilled, the median depth is 90 ft (middle half 54 ft–139 ft), median tested yield 15 gpm, and median static water level 30 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1980–2023" refers to the earliest and latest well logs attributed to this company in the EGLE database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
