Well characteristics
Across the wells Tatay Pump Services has drilled, the median depth is 105 ft (middle half 80 ft–140 ft), median tested yield 20 gpm, and median static water level 35 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1976–2026" 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.
