Well characteristics

Across the wells Macs Pump Service has drilled, the median depth is 140 ft (middle half 110 ft–189 ft), median tested yield 25 gpm, and median static water level 22 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1962–2010" 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.
