Well characteristics

Across the wells Pacific Gas And Electric Company has drilled, the median depth is 140 ft (middle half 87 ft–170 ft), median tested yield , and median static water level 59 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1955–2018" 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.
