Well characteristics

Across the wells H-F Drilling, Inc. has drilled, the median depth is 42 ft (middle half 26 ft–71 ft), median tested yield 35 gpm, and median static water level 35 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1988–2001" 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.
