Well characteristics
Across the wells Katz Well Drilling Inc. has drilled, the median depth is 102 ft (middle half 76 ft–130 ft), median tested yield 30 gpm, and median static water level 26 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1966–2026" 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.
