Well characteristics
Across the wells J & H Drilling Co. Inc. has drilled, the median depth is 36 ft (middle half 21 ft–55 ft), median tested yield 2 gpm, and median static water level 36 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 2005–2026" 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.
