Well characteristics

Across the wells Ase Drilling Inc. has drilled, the median depth is 256 ft (middle half 201 ft–317 ft), median tested yield 50 gpm, and median static water level 59 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1975–2013" 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.
