Well characteristics

Across the wells Harris A J Co. has drilled, the median depth is 220 ft (middle half 158 ft–302 ft), median tested yield 16 gpm, and median static water level 70 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1973–1979" 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.
