Well characteristics
Across the wells Cal Prime Pump Sales has drilled, the median depth is 75 ft (middle half 51 ft–120 ft), median tested yield 10 gpm, and median static water level 14 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1992–2025" 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.
