Well characteristics

Across the wells Canepa And Sons Inc. has drilled, the median depth is 420 ft (middle half 300 ft–625 ft), median tested yield 25 gpm, and median static water level 96 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1936–2026" 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.
