Well characteristics

Across the wells Seanaco Inc. has drilled, the median depth is 221 ft (middle half 160 ft–304 ft), median tested yield 35 gpm, and median static water level 60 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1982–2005" 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.
