Well characteristics

Across the wells J Field Drilling Co. has drilled, the median depth is 230 ft (middle half 166 ft–303 ft), median tested yield 8 gpm, and median static water level 50 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1975–2010" 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.
