Well characteristics
Across the wells United Drilling & Exploration Co. has drilled, the median depth is 100 ft (middle half 74 ft–147 ft), median tested yield 30 gpm, and median static water level 17 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1954–2005" 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.
