Well characteristics
Across the wells Superior Pump & Drilling Inc. has drilled, the median depth is 140 ft (middle half 105 ft–195 ft), median tested yield 7 gpm, and median static water level 25 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 2004–2026" refers to the earliest and latest well logs attributed to this company in the DWR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
